Connector SE for Exchange OAuth integration


Historically, ACRM has been synchronizing user’s email, contacts, and appointments with Microsoft Exchange using a custom connector and authenticates using Basic Authentication.


Microsoft has announced that in the second half of 2021, basic authentication will be discontinued.

Hence, to keep the synchronize function working, the basic Authentication using Microsoft exchange is replaced by OAuth Authentication with application permissions.
