Hi
We have multiple physical sites and only 1 active directory site. Email environment is pure on-premises exchange 2013. Each physical site has CAS/Mailbox servers. There are not IP restrictions between these physical sites. Everything is outlook anywhere obviously.
I would like to introduce NEW AD sites for each of these physical locations.
Do you see any major issues that I need to be aware of?
Can this be done in the middle of the day?
Will there be pop ups in outlooks and disconnects?
I appreciate your help.
