O365: Exchange and AD – How msExchRecipientDisplayType and msExchangeRecipientTypeDetails Relate to Your On-Premises

Often, in O365, there's a reference field we use to specify what a recipient type is, as far as on-premises AD/Exchange is concerned. If you weren't already aware, this is how the attributes relate:

Recipient Display Type = msExchRecipientDisplayType
Recipient Type Details = msExchRecipientTypeDetails

Like many other Active Directory Attributes, these are represented by Integer Values in Active Directory. One important item to note here is that you do not want to arbitrarily change these values: the Recipient Display Type is something that should only be set by Exchange. Changing it via any other method is not supported.

Here is how the Recipient Display Type Breaks down:

Display Type Value

DynamicDistributionGroup 3

    Hi,Many thanks for this info.
    I would also be extremly interested in having detailed information about the MsExchRemoteRecipientType attribut.

  2. UnderCoverGuy says:

    AWESOME – looked all over for this type of detail for this info.

    Thanks a lot

    Great info that SHOULD be on msdn. Thanks!

  5. Joe F. says:

    Excellent info John. Can you post the values for msExchRemoteRecipientType? That would be very helpful! Thank you.

  6. HA says:

    Is the value for msExchRecipientDisplayType editable? and how? or what decides that value? where does it come from?

  7. Andy Martin says:

    I believe there is a mistake – for SecurityDistributionGroup the value is listed as "1043741833" but I believe this should be "1073741833" based on my lookups from our On-Prem Exchange.

      You have setup a hybrid between on-premises Microsoft Exchange and Office 365 (Exchange Online

  9. Dustin Dortch says:

    for msExchRemoteRecipientType, I know of two values:

    1 – ProvisionMailbox
    4 – Migrated

    It would stand to reason that there is at least also some appropriate values for 3 and 4, if not 0 or 5 and beyond.

    When you execute Enable-RemoteMailbox, the AD user object has msExchRemoteRecipientType set 1 which will tell the Service to provision a new mailbox for the user when it is next synchronized. A value of 4 means that the mailbox was migrated from On-Premise
    to Online.

    How can my Azure app get these properties from Azure AD? I didn’t find them in Graph API.

  11. Gilford Grijt says:

    msExchRecipientTypeDetails 34359738368 (36th bit on) is RemoteSharedMailbox

    Hi, How to get values for msExchRecipientTypeDetails for particular users

    1. Marci says:

      Run the following script to pull all AD attribute values for individuals:
      Get-ADUser username -Properties * | Select * | out-file c:\users\\desktop\username.txt

      Use this script for just the msExchRecipientDisplayType and msExchRecipientTypeDetails values:
      Get-ADUser username -Properties * | fl Name,SamAccountName,msExchRecipientDisplayType,msExchRecipientTypeDetails | out-file c:\users\\desktop\ExchRecipValues.txt

      Run this script to pull those 2 values for all users in your domain.

      Get-ADUser -SearchBase “OU=All Users,DC=X,DC=Y,DC=Z,DC=com” -Filter {Enabled -eq $true} -Properties * | fl Name,SamAccountName,msExchRecipientDisplayType,msExchRecipientTypeDetails,DistinguishedName | out-file c:\users\\desktop\ExchRecipValues.txt

      You can import this into an excel file and modify it to make it pretty. ūüôā (Macros help with large amounts of data/users)

    Hi John,

    This article has helped me alot to resolve multiple issues with mailboxes. Thank you

    However i fail to understand the difference between ACLableMailboxUser with value 1073741824 and a Mailboxuser with value 0

    Considering a single AD forest, when i enable a mailbox why does it associate teh user with ACLablemailboxuser and y doesnt it have a 0 i.e. a mailbox user

    If ACl is refereed to Inheritance permission, then i can do that via AD under security tab as well.

    Any thought would be much appreciated

  15. Ryan F. says:

    I can confirm these values on Exchange 2016 for Recipient Type Details although they should be good for older versions as well.

    Great Advice John! Very Helpful!

  17. This list is missing 549755813888 which is for Health Monitoring Mailboxes. With that said I can’t seem to find a definitive list on Technet library that lists all recipient types. Does this not exist? It took a lot of searching just to find this blog.

  18. thommck says:

    In my hybrid environment the Exchange recipient type is actually listed under CloudExchangeRecipientDisplayType
