I upgraded from CU7 to CU8 and now my public folders are gone.

The Public Folder Mailbox is still here but nothing is listed under Public Folders.

Any suggestions?

If I try to create a new public folder I get an error:

Cannot open mailbox /o=Astrodomain/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=SMG-EXCHANGE/cn=Microsoft System Attendant.

Figured it out <g class="gr_ gr_4 gr-alert gr_gramm Grammar multiReplace" data-gr-id="4" id="4">myself</g>, ran the following command and it repaired the issue:

Get-MailboxStatistics -Database Database name | ForEach { Update-StoreMailboxState -Database $_.Database -Identity $_.MailboxGuid -Confirm:$false }
