Connect to two different exchange servers in two different domains from outlook 2016.
We have old domain running exchange 2013, on olddomain.local. We have exchange 2016 running on newdomain.local. All computers are joined to olddomain and have email boxes that are email@example.com. User names on the old domain are 123.
On the new domain we have domain users named abc, and email addresses that are firstname.lastname@example.org.
The user names 123 and abc are the same person, they have one ID on the old domain and a different one on the new domain....don't ask me why it is a battle I fought and lost.
Currently the way things are configured is if you send a mail to email@example.com it will go to 123's mailbox. If you sent a mail to abc@public it will go to the correct mail box. You can access abc's email via the OWA client. If you log into a machine that is on the newdomain.local domain you will get outlook mail that goes to abc's user.....all that is working correctly.
What I would like is for the users on the olddomain to have access to their email on the new domain via outlook and not the web client.
I have checked this case:
And for some reason I can't get it to take the user ID or password for the new account....the same issue the OP had in the 3rd post...but can't get it to take the user name/password.
My setup I think is the same as his....two different domains, two different exchange servers, mine are a 2013 and a 2016.
I am working on several issues with this email box so I will likely be posting a few questions on this in a few threads.
