We just swapped out a new router, and changed from a class C to a class B subnet range. All of our outlook clients are able to connect to exchange, but the performance is really slow. When a user hits send, they have to wait about 30 seconds
before the email actually goes. It sits there and a message pops up saying Outlook is requesting data from the server. I've added in the new IP Range into the receive connector in the server configuration hub transport, but there is still quite
a delay. Also, the OWA is slow when you compose a new email. Any assistance would be appreciated. Thank you.
