Hi There,
 
Very strange but D365 App for outlook throwing an error when clicked on it.
 
Interesting part is when users are within office then issue does not come, but when users are outside of the office Authentication issue comes from outlook desktop.
 
Second interesting part is that when outlook is browse though web browser then D365 App for outlook works.
 
Can anyone guide me what can be the glitch here.
