I’ve been successfully utilising the Microsoft Email Service via the Emailer transformer for sometime - I noticed last week that all emails scheduled to run via FME flow stopped working, and when I opened the workspaces to reauthorise Microsoft, I was met with the following error:

 

“Unable to retrieve access token

Request to update access token failed. HTTP Error: HTTP/1.1 401 Unauthorized”

 

My IT department can see on their end that the logins have been successful via FME Emailer Enterprise Application on Azure.

 

 

A 401 response indicates that the authentication portion of the request failed - https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401

 

Are your credentials correct?

I would suggest that you probably need to watch all the calls and responses with something like fiddler, to understand where in the multiple calls it is actually failing. Especially, if IT department says that one of the calls is authenticating.

Yes they are, it fails post multi authentication

for clarification, it's failing during Microsoft connection login, before any calls take place

Yes, its those calls to the Microsoft connection login that I think you should be looking at (the ones that you don’t see in any log file in FME)
