You can just type get-tip in the Exchange Management Shell, but if you want a specific one type get-tip 8 and you wil get #8.  Anyway here is the current list and the commands so you can list it yourself! 😉

[PS] C:\>for ($i=1; $i -lt 81; $i++) {get-tip $i}

– OR -

[PS] C:\>1..80 | foreach { get-tip $_ }

Tip of the day #1:
To return all scripts that are found in your path, type:

 Get-Command -Type ExternalScript

And for a useful shortcut, assign it in your profile as:

 Function Get-Scripts { -Command -Type ExternalScript }

Tip of the day #2:
Are you tired of typing a long command every time that you want to do something?
Alias it! Type:

 Set-Alias GetSg Get-StorageGroup

For all the current aliases, type:


Tip of the day #3:
The Exchange Management Shell is a calculator too! Try it directly in the command line:

 1.2343+3123 or (23/435)*2

Tip of the day #4:
Command line 911! Do you need help? Type:

 Help <cmdlet-name>  or  <cmdlet-name> -?

You can also perform wildcard character searches and partial name matches:

 Help *UM*

And you can get more details about a cmdlet by using:

 Get-Command <cmdlet-name>

Tip of the day #5:
A quick shortcut to get all the parameters for a cmdlet is:

 Get-Command <cmdlet-name> | format-list Definition

or abbreviated:

 Gcm <cmdlet-name> | fl Def*

Tip of the day #6:
The tilde character (~) should be familiar to Unix users. It represents the shortcut to your root directory. To see what it's evaluated to by default, type:

 Dir ~

You can use it as a useful shortcut:

 Cp SomeFile "~\My Documents"

Tip of the day #7:
Do you want to move mailboxes? Type:


You can move all users from server SRV1 to server SRV2 as follows:

 Get-Mailbox -Server SRV1 | Move-Mailbox -Target SRV2

Tip of the day #8:
CTRL+C is the equivalent of the hard-break command in the Exchange Management Shell. If a command is taking too long to run or you want to cancel an operation quickly, press CTRL+C to stop execution.

Tip of the day #9:
Pushd and Popd work the same way in the Exchange Management Shell as they do in cmd.exe. Type:

 Pushd <location>

Tip of the day #10:
XML over everything! The Exchange Management Shell treats XML as a native type, so that you can do interesting things like:

 $Sample = [XML](Get-Content SomeXMLFile.xml)

This command assigns $Sample to the actual XML object. To see it, type:


To navigate it, type:

No need for text parsing when you want to load XML data!

Tip of the day #11:
Identity is your friend. Identity is a powerful construct that lets you view, modify, or remove a particular Exchange object or configuration set by referring to it by a friendly name. Additionally, you can even specify server name as part of the identity. For example: the following command will try to find "First Storage Group" on the localhost because no server was specified:

 Get-StorageGroup "First Storage Group"

If you know exactly where "First Storage Group" is, you can use:

 Get-StorageGroup "Server1\First Storage Group"

This same pattern can be applied to all Active Directory-based configurations.

Tip of the day #12:
Cmdlets that end in "Config" manage singleton configuration, either one per server or organization. For these tasks, you don't have to specify an identity because there is only one instance of the configuration. You may have to specify the Server parameter if the configuration is per server.

Tip of the day #13:
To get a list of all users on an Exchange 2007 server who are not Unified Messaging-enabled type, use:

 Get-UmMailbox | ForEach { If($_.UmEnabled -Eq $False){$_.Name}}

Tip of the day #14:
To get a list of all users on an Exchange 2007 server who are Unified Messaging-
enabled type, use:

 Get-UmMailbox | ForEach { If($_.UmEnabled -Eq $True){$_.Name}}

Tip of the day #15:
To display the user's alias formatted in a table together with the user's Exchange 2007 server name and telephone extension, type:

 Get-UmMailbox | Format-Table ServerName,@{e={$_.SamAccountName};Label="User Alias"},@{Expression="Extensions";Label="Telephone numbers"}

Tip of the day #16:
To display the list of UM IP gateway server names that are disabled for outbound calling and hunt groups that are associated with a UM IP gateway server, use:

 Get-UmIpGateway | ForEach {If($_.OutCallsAllowed -Eq $False){ "Gateway Name = " +$_.Name;ForEach ($HuntGroup In $_.Huntgroups){"Huntgroups " + $Huntgroup

Tip of the day #17:
If you want to test all IP Block List providers, you just have to pipe the Get-IpBlockListProvider cmdlet to the Test-IpBlockListProvider cmdlet:

 Get-IpBlockListProvider | Test-IpBlockListProvider -IpAddress

Tip of the day #18:
Before you remove an object by using the Remove verb, use the WhatIf parameter to verify the results are what you expect.

Tip of the day #19:
Sometimes it's useful to convert a cmdlet's output to a string to interoperate with native cmdlets. For example, type:

 Get-Command | Out-String | Findstr "command"

Tip of the day #20:
Do you want to find a specific string in the output of a cmdlet? Match-String is a grep clone that is useful for matching output with strings. Try it out:

 Dir | Match-String "somename"

Tip of the day #21:
Get all Win32 WMI information, such as perfmon counters and local computer configurations. For example, type:

 Get-WMIObject Win32_PerfRawData_PerfOS_Memory

Tip of the day #22:
Tired of spam? Who isn't? You can configure real-time block list (RBL) providers with the Exchange Management Shell by running the following two commands:

 Set-IPBlockListProvidersConfig -Enabled $True -InternetEnabled $True

and then

 Add-IPBlockListProvider -Name <Name of RBL Provider> -LookupDomain <FQDN of RBL Provider> -ResultType Any

Tip of the day #23:
Access the event log from the Exchange Management Shell. To retrieve the whole event log, run:

 Get-EventLog | Format-List

To retrieve all Exchange-related events, run:

 Get-EventLog Application | Where ($_.Source -Ilike "*Exchange*")

Tip of the day #24:
You can arrange the output of most cmdlets in a more readable manner by piping the output of the cmdlet to Format-List or Format-Table. For example, type:

 Get-EventLog Application | Format-List

Tip of the day #25:
One benefit of the Exchange Management Shell is that cmdlets can emit objects to the console. You can then manipulate this output and organize it in interesting ways. For example, to get a quick view in tabular format, use Format-Table:

 Get-Mailbox | Format-Table FirstName,LastName,ServerName

Tip of the day #26:
Did you forget a property name? Not a problem because you can use wildcard characters to retrieve all properties that match the part of the name that you specify:

 Get-Mailbox | Format-Table First*,SMTP*

Tip of the day #27:
Do you want to work with data that is contained in a CSV file? Use Import-CSV to assign the data to an object. For example, type:

 $MyCSV = Import-CSV TestFile.CSV

You can then manipulate the data easily in the Exchange Management Shell. For example, if there is a column called Mailboxes in the CSV data, you can use the following commands to sort or group the data by the Mailboxes column:

To sort: $MyCSV | Sort Mailboxes
To group: $MyCSV | Group Mailboxes

Tip of the day #28:
This command spins through all your mailbox servers and reconnects all the uniquely identified but disconnected mailboxes in any one of the mailbox stores:

 Get-ExchangeServer | `
  Where { $_.IsMailboxServer -Eq '$True' } `
  | ForEach { Get-MailboxStatistics -Server $_.Name `
  | Where { $_.DisconnectedDate -NotLike '' } `
  | ForEach { $Var | Connect-Mailbox -Identity `
    $_.MailboxDisplayName } }

Tip of the day #29:
Tab completion reduces the number of keystrokes that are required to complete a cmdlet. Just press the TAB key to complete the cmdlet you are typing. Tab completion kicks in whenever there is hyphen (-) in the input. For example:


should complete to Get-SendConnector. You can even use regular expressions, such as:


Pressing the TAB key when you enter this command cycles through all cmdlets that  match the expression, such as the Unified Messaging Mailbox policy cmdlets.

Tip of the day #30:
Do you want to create a group of test users in your lab? Use this command:

 1..100 | ForEach { Net User "User$_" MyPassword=01 /ADD /Domain; Enable-Mailbox "User$_" -Database "<Mailbox Database>" }

Tip of the day #31:

Tip of the day #33:
Do you want to set the properties on all or some Outlook Web Access virtual directories? Pipe the output of Get-OwaVirtualDirectory to the Set-OwaVirtualDirectory cmdlet. For example, the following command sets the Gzip level for all Outlook Web Access virtual directories:

 Get-OwaVirtualDirectory | Set-OwaVirtualDirectory -GzipLevel High

Tip of the day #34:
Do you want to remove an ActiveSync device from a user's device list? Type:


This cmdlet can be helpful for troubleshooting devices that do not synchronize successfully with the server.

Has one of your users asked you to recover their mobile device synchronization password? To return the user's password, type:

 Get-MobileDeviceStatistics -ShowRecoveryPassword

Tip of the day #38:
Do you want to move the storage group path to another location? Type:

 Move-StorageGroupPath -EdbFilePath DestFileName

To change only the path setting without moving data, use this command together with the ConfigurationOnly parameter. This command is especially useful for disaster recovery. Caution: Misuse of this cmdlet will cause data loss.

Tip of the day #39:
Do you want to move your database path to another location? Type:

 Move-DatabasePath -LogFolderPath DestFolderName

To change the file path setting without moving data, use this command together with the ConfigurationOnly parameter. This command is especially useful for disaster recovery. Caution: Misuse of this cmdlet will cause data loss.

Tip of the day #40:
Not all parameters of a task are viewable through Get-Command. To get a dynamicparameter, type:

 Get-DynamicParameters <Cmdlet>

Tip of the day #41:
To set the dial restrictions on a specific Unified Messaging dial plan, type:

 $Dp = Get-UmDialPlan -Identity <Your_DialPlan_Identity>
 $Dp.OutsideLineAccessCode = 9
 $Dp | Set-UmDialPlan

Tip of the day #42:
Do you want to reconnect a large number of disconnected mailboxes? Type:

 Get-MailboxStatistics | Where {$_.DisconnectDate -ne $Null} | Connect-Mailbox -Database <MailboxDatabase>

Tip of the day #43:
Do you need an easy way to add a new primary SMTP address to a group of mailboxes? The following command creates a new e-mail address policy that assigns the domain to the primary SMTP address of all mailboxes with Contoso in the company field:

 New-EmailAddressPolicy -Name Contoso -RecipientFilter {Company -Eq "Contoso"} -EnabledPrimarySMTPAddressTemplate ""

Tip of the day #44:
Do you want to retrieve a group of objects that have similar identities? You can use wildcard characters with the Identity parameter to match multiple objects. Type:

 Get-Mailbox *John*
 Get-ReceiveConnector *
 Get-JournalRule *discovery*

Tip of the day #45:
Do you want to configure a group of objects that have similar identities? You can use a wildcard characters with the Identity parameter when you use a Get cmdlet and pipe the output to a Set cmdlet. Type:

 Get-Mailbox *John* | Set-Mailbox -ProhibitSendQuota 100MB

This command matches all mailboxes with the name "John" in the mailbox's identity and set the ProhibitSendQuota parameter to 100MB.

Tip of the day #46:
Most cmdlets let you pass the output of one noun to another noun in order to view or modify related objects. For example, you might want to set the mailbox limit on all mailboxes that reside in a specific mailbox database on a server. You can do this by using this command:

 Get-MailboxDatabase "Executives" | Get-Mailbox | Set-Mailbox -ProhibitSendQuota 300MB

This command retrieves all the mailboxes that reside in the "Executives" mailbox  database and sends their ProhibitSendQuota value to 300MB.

Tip of the day #47:

 Set-Mailbox -Prohibit*<tab>

Tip of the day #48:
Say goodbye to ping. Say hello to Test-MapiConnectivity! Use Test-MapiConnectivity to troubleshoot connectivity problems between your users and your servers. Combine Test-MapiConnectivity with a variety of cmdlets to target your specific issue without having to manually dig for the information:

Mailboxes: Get-Mailbox <Mailbox Name> | Test-MapiConnectivity
Mailbox databases: Get-MailboxDatabase <Database Name> | Test-MapiConnectivity
Servers: Get-MailboxServer <Server Name> | Test-MapiConnectivity

Tip of the day #49:
Do you want to add an alias to multiple distribution groups that have a similarname? Type:

 Get-DistributionGroup *Exchange* | Add-DistributionGroupMember -Member kim

This command adds the alias "kim" to all distribution groups that contain the word "Exchange".

Tip of the day #50:
Do you want to record exactly what happens when you're using the Exchange Management Shell? Use the Start-Transcript cmdlet. Anything that you do after you run this cmdlet will be recorded to a text file that you specify. To stop recording your session, use the Stop-Transcript cmdlet. Notice that the Start-Transcript cmdlet overwrites the destination text file by default. If you want to append your session to an existing file, use the Append parameter:

 Start-Transcript c:\MySession.txt -Append

Tip of the day #51:
Here's a handy tip for repeating a command a given number of times. Instead of writing a For loop, use the following syntax:

 1..10 | ForEach { "do something here" }

For example, the following command creates 10 new storage groups that have the names sg1 through sg10 on the server TestServer:

 1..10 | ForEach { New-StorageGroup -Name "sg$_" -server TestServer }

Tip of the day #52:
Do you want to know when your mailbox databases were backed up last? Type:

 Get-ExchangeServer | Get-MailboxDatabase -Status | Format-Table Name, *Back*

Tip of the day #53:
Do you want to move all the mailboxes from one mailbox database to another? You can do this easily by using the following command:

 Get-MailboxDatabase <Source Mailbox Database> | Get-Mailbox | Move-Mailbox -TargetDatabase <Destination Mailbox Database>

You can even use wildcard characters with the Get-MailboxDatabase cmdlet to consolidate mailboxes from multiple source mailbox databases into a single destination mailbox database.

Tip of the day #54:
Do you have a user who has network access but maintains an external mail account outside your Exchange organization? With Exchange Server 2007, you can now create mail-enabled users that are regular Active Directory accounts, but also behave like mail-enabled contacts. By using the Enable-MailUser cmdlet, you can add e-mail contact attributes to any existing Active Directory user who does not already have a mailbox on an Exchange server. Users in your Exchange organization will then be able to send e-mail messages to that user's external mail account. Type:

 Enable-MailUser -Identity <Active Directory Alias> -ExternalEmailAddress <Destination SMTP Address>

Tip of the day #55:
Do you want to change the default prohibit send quota for a mailbox database? Type:

 Set-MailboxDatabase <Mailbox Database Name> -ProhibitSendQuota <New Quota Size>

You can specify a bytes qualifier when you use the ProhibitSendQuota parameter.
For example, if you want to set the prohibit send quota to 200 megabytes, type:

ProhibitSendQuota 200MB

You can also configure the IssueWarningQuota parameter and the ProhibitSendReceiveQuota parameter in the same way.

Tip of the day #56:
Do you want to know what version of Exchange Server each of your servers is running? Type:

 Get-ExchangeServer | Format-Table Name, Version

Tip of the day #57:
Do you want to know which Exchange 2007 servers have not yet been configured with a valid product key and whether their trial period has expired? Type:

 Get-ExchangeServer | Where { $_.IsExchange12TrialEdition -Eq $true } | Format-Table Name, *Trial*

Tip of the day #58:
Do you want to determine whether a server is running Exchange Server 2007 Standard or Exchange Server 2007 Enterprise? Type:

 Get-ExchangeServer <Server Name> | Format-Table Name, Edition

If you want to view which edition all your Exchange servers are running, omit the <Server Name> parameter.

Tip of the day #59:
Do you want to create a new resource mailbox that can be used to book a meetingroom? Type:

 New-Mailbox -Name <Conference Room Name> -UserPrincipalName <Alias or SMTP Address> -Database <Mailbox Database> -OrganizationalUnit <Organizational Unit> -ResourceType Room

This command creates a disabled Active Directory user with a mailbox that accepts meeting requests from users.

Tip of the day #60:
Do you want to add a disclaimer to all outbound e-mail messages? Type:

 $Condition = Get-TransportRulePredicate FromScope
 $Condition.Scope = "Internal"
 $Condition2 = Get-TransportRulePredicate SentToScope
 $Condition2.Scope = "External"
 $Action = Get-TransportRuleAction ApplyDisclaimer
 $Action.Text = "Sample disclaimer text"
 New-TransportRule -Name "Sample disclaimer" -Condition @($Condition, $Condition2) -Action @($Action)

Tip of the day #61:
Do you want to control the properties of e-mail messages sent to a specific domain? Use the RemoteDomain cmdlets. Create a new remote domain by using the New-RemoteDomain cmdlet. Type:

 New-RemoteDomain -Name " Configuration" -DomainName
