Hi all,

I'm not sure if this is intended behaviour or not, but any distribution group we create in Exchange ECP does not update in Active Directory Users and Computers. Any particular reason why?

For example, we have a user group called "Managers" and we've recently created a new group called Area Managers.

Hi Zach,

How many DCs \ Sites do you have.

Please check if active directory replication is fine. Normally it might take upto 60mins - 3hrs depending upon the environment.

For future reference, we'll manually choose an OU rather than accepting default settings! Thanks everyone for the help a
