Manage Permissions result in 500 Unexpected Error (Public Folders Exchange 2013)

Although you can manage permissions in Exchange Management Shell, in ecp when you click on Manage Permissions on specific folder the following page is shown:

500 Unexpected Error

500 Unexpected Error

To resolve this issue:

1. Use PowerShell to check Public Folder Client Permissions:
PS > Get-PublicFolderClientPermission \FolderName |Format-List

2. Check if any user has a SID instead of a username

3. Remove users with SID if any:
PS > Remove-PublicFolderClientPermission -Identity \FolderName -User NT:S-1-1-11-11111111-1111111111111-1111

4. Check if you can manage Public Folder permissions via ecp

    What if I’m not finding any rogue SID with the first power shell command?

    Only thing I see that might be out of place is some user named Anonymous that shouldn’t be there that I can’t delete.

      This solved the problem in my specific situation. If you have found another solution, I would appreciate if you would share it.

    I ran Get-PublicFolderClientPermission \FolderName |Format-List and it returned it couldn’t find a process with the name \foldername – I hate powershell so very deeply.
