To find the mailbox causing this error you can use the following Exchange Management Shell command:
Get-MailboxStatistics | where { $_.MailboxGuid -eq ‘1d8768d9-cd02-4746-9c16-d6a212b4e5ea’ } |ft displayname,mailboxguid
Change the GUID in the command to match the code you get in the error.
I love PowerShell!

  1. Or you could use Get-Mailbox -Identity GUID.

    In our case:

    Get-Mailbox -Identity 1d8768d9-cd02-4746-9c16-d6a212b4e5ea
