Public Folder Migration Fail #2

Another day, another Public Folder migration failure. This time, on testing your Public Folder migration to Office 365, they appear to be unavailable and are not visible in the Outlook client.

I always follow the wonderful guide provided by Microsoft on how to migrate your Public Folders from Exchange > Office 365 (I’m not being sarcastic, it is actually a good guide) available here: https://technet.microsoft.com/en-GB/library/dn874017(v=exchg.150).aspx

The last two times I have run through this process, I have attempted to test the PF Migration on a single user prior to going live for all users. Microsoft suggest the following command for doing this:

Set-Mailbox -Identity <Test User> -DefaultPublicFolderMailbox <Public Folder Mailbox Identity>

However since the Exchange 2016 wave of Office 365 has gone live, this command no longer appears to have the desired effect. What seems to happen is that because the -IsExcludedFromServingHierarchy parameter is set to $true, the command does not fully enable the Public Folders for that user.

In both situations, I have taken the plunge and enabled Office 365 Public Folders for all users by running:

Get-Mailbox -PublicFolder | Set-Mailbox -PublicFolder -IsExcludedFromServingHierarchy $false

The end result (after a little patience) is that Public Folders become available for all users. I’m not sure if this is a general bug or a result of the Exchange 2016 backend of Office 365, but I’d be interested to hear your experiences!
