I have configured DAG such that i have 1 mailbox server (MB01) in Primary location and 1 mailbox (MB02) server in secondary location. Both have each other's database copies and are mounted and healthy. Witness server is at another location.
For now i haven't made the virtual directories on both servers same. They are mb01.domainname/owa and mb02.domainname/owa etc
(We don't require internet connectivity so using only internal urls)
I have a third Exchange 2010 (nhq-mg01) server from where the user's will be migrated to the Exchange 2016 server. I have tested a few users by migraying them and they work fine in new 2016 server. But the problem is with my Outlook configuration.
When i access my 2010 server via its web link it points to mb02 server. It should point to my primary server i.e mb01. I don't understand from where this setting is coming from.
Then, in my outlook, under account information the web url that is being showed is correct i.e mb01
But if i go to Exchange proxy settings (under the account settings) the url of mb02 server is shown. Although i haven't configured any outlook settings.
Moreover, if i test dag by disconnecting my primary server (making it offline), the mb02 server works fine but only on the web.
My outlook gets disconnected and even after primary is back online it tries to connect to mb02 sometimes and gives error that certificate name doesnt match and sometimes connects to mb01 correctly.
Any help will be greatly appreciated.
