Distribution list missing from Exchange 2007 server, wasn't delete, can't re-add, says name is in use
Posted on 2013-12-04
Users complained the couldn't email a security group that'd been mail enabled. They saw the following:
The recipient's e-mail address was not found in the recipient's e-mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try resending this message, or provide the following diagnostic text to your system administrator.
I checked AD and the group is still there, but it's missing from Exchange and no one's deleted it. I tried to create a new one with the same one and got this:
Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:00:00
The value "______" of property "SamAccountName" is used by another recipient object "domain/domains Groups/Group name". Please specify another value.
Exchange Management Shell command attempted:
new-DistributionGroup -Name 'International Group' -Type 'Security' -OrganizationalUnit 'domain/Users' -SamAccountName 'International Group' -Alias 'InternationalGroup'
Elapsed Time: 00:00:00
So somehow it's missing from exchange while still being in AD and it won't let me re-create it. Using a different name is problematic. Any ideas? THanks.
