Exchange 2013 Default Domain Change - Do new Outlook Profiles need to be created for all users?
Posted on 2016-09-13
I need to set a new accepted default domain for mail in Exchange 2013.
Once I officially set the new domain as a default and apply the email policies, will the users be able to send mail from the new domains using their existing Outlook profiles and will they have the new From address?
I know that if I create a new profile, the new address appears after setup and everything works but I would like to use the existing profiles. Some of the users have large OST files so I am not keen to create new profiles with new OST's.
Currently I find that users logging into Outlook use existing profiles, and the From address does not change to any other other (even though the default reply address has been changed in Exchange for that user).
Thanks in advance,
