Exchange 2013CU22
Dynamic distriubtion Groups which where migrate from Exchange 2010 works. But all new dynamic Distribution Groups dont send any email to member of Group. I create all new Groups over PowerShell i filter member by City i can Show memebers of dynamic Distribution Group over PowerShell i see the members.
But when i send a E-Mail to the dynamic Distribution Group. As Sender it look everything ok. you dont get any error.
But fact ist that no one of members become E-Mail.
I compare the Settings between Groups which which were created in exchane 2010 and now in 2013. But i cannot find any differences.
Any ideea? what could be the failure?
