SUMMARY STEPS TO REPRODUCE 1. Create a new EWS account to open a Microsoft Exchange Configuration window. 2. Note that the OK button is disabled, and becomes enabled when you enter a username and password. Delete the username and password so the OK button becomes disabled again. 3. Select OAuth2 radio button. Notice that the username and password fields are disabled, and so is the OK button. The OK button will stay this way even after you enter all other necessary settings. OBSERVED RESULT You can't OK the configuration. Workaround is to switch the radio button, put something in a username and password (which defeats the purpose of OAuth2 if you use your actual username and password) then switch it back to OAuth2. The content stays in the fields even though they are disabled. EXPECTED RESULT OK button enabled if OAuth2 selected.
