Full hierarchy sync fails with Microsoft.Mapi.MapiExceptionMaxSubmissionExceeded

Original KB number:   3068989


A full hierarchy sync to a public folder mailbox fails with a Microsoft.Mapi.MapiExceptionMaxSubmissionExceeded error.


The sync state of the public folder hierarchy exceeds the maximum message size.


Increase the value of the MaxSendSize and the MaxReceiveSize parameters for all public folder mailboxes. To do this, run the Set-Mailbox cmdlet.

Set-Mailbox -Public <PFMailboxName> -MaxSendSize 30MB -MaxReceiveSize 30MB
