We have upgraded to Exchange 2013 from 2010. This morning an All User e-mail was sent and it didn't go to everybody. Looking at the All User dynamic distribution group, under Membership I'm receiving the following error message.
Current Filter:
(&(!cn=SystemMailbox{*})(& (mailnickname=*) (| (&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*))) )))
Error message:
This dynamic distribution group is corrupted or was created in an earlier version of Exchange. Use the Exchange Management Shell to change the filter.
How do I change this is the correct setting?
