Migrating Hybrid Public Folders to Office 365

So, tonight I started the last phase of one of my longest-running projects since joining Microsoft–an Exchange Online migration for a school district that I began nearly a year and a half ago.  40,000 mailboxes down and 13,000 public folders remaining. One of the things that we recommend for Hybrid Public Folders is that you…

AAD Connect Error CD-8235 Exporting to AD Connector

This afternoon, I ran into a customer with a very interesting configuration–a 300-user department with 15 domain controllers spread among 6 sites. Which, given our guidance in the past didn’t seem that out of line (redundant domain controllers at each site to process logons). What made it really interesting was that each site (including the…

Testing AD FS for Office 365 without Directory Synchronization

Let’s say you’re in one of the following scenarios: You need to set up AD FS for a shared hosting environment and won’t have any identities synchronized from the forest where AD FS will be deployed and want to verify that the AD FS infrastructure is working. You need to stage AD FS before you’re…

Troubleshooting Mailbox Migration Error “You can’t use the domain because it’s not an accepted domain for your organization.”

While migrating users via MRS between organizations (especially to Exchange Online), a pretty common error that I run across is: You can’t use the domain because it’s not an accepted domain for your organization. This error is generated because the MailUser object of the user you’re attempting to migrate has a proxy address attached to…

Removing Proxy Addresses from Exchange Recipients

I saw a request come through the other day for a method to remove unwanted proxy addresses for contacts.  I’d had some code sitting around from a project a few years back and decided to freshen it up, and maybe add some newer tricks. So, the original idea was to select a bunch of users…

Today’s tool fulfills all of those…

Export and Import Calendar Processing Information

During my current project, it became necessary to capture additional calendar processing parameters that are not preserved during a normal hybrid move–such as booking policies. Some of the challenges that I faced with this tool: Blank or unpopulated attributes Conversion of sAMAccountName values to PrimarySmtpAddress Multiline attributes with special characters Attributes that were set for…

Checking for an elevated PowerShell prompt

I just built a tool for a team of consultants to use, and some of the commands require elevation.  Rather than relying on telling them it needs to be elevated, I wanted to be able to exit immediately if the session wasn’t so precious time wasn’t wasted. First, we need to figure out who the…

Mailbox Delivery Settings

From time to time, I run into environments where things are configured in “non-standard” ways.  Granted, we don’t have a lot of specificity or documentation around some attribute configurations because the default configuration has been tested by the people who created the software and works in almost every conceivable situation.  However, we do run into…
