Outlook has a problem with logging in to a domain that is different to your local domain. So, this happens if your server is hosted outside of your local network.
To fix this problem open up your registry. (Start>Run or Search for Regedit)
The navigate to
Then modify the value of:
lmcompatibilitylevel to 2
If it doesn’t exist add a new “String Value“, call it “lmcompatibilitylevel” and modify the value to 2
This should allow outlook to open without prompting to login.
