Since the most recent update (7.2.36465.0) MS Exchange will not connect. The account settings have not changed, and the Gmail account works as before.
So that version has not officially been released and it appears that those who downloaded it are experiencing some issues.
The solution is to downgrade eM Client to the previous version, 7.2.35595.0, where it was working. To do that uninstall eM Client making sure NOT to delete the database, then download and install the previous version from the Release History
Ok, thanks, I will do that. I had a Win 10 notification come up about the update, which is why I updated.
