Microsoft Exchange server error "User is authenticated but not connected."

AntonioC7 Dear Antonio. I have spent the last 4 hours online with MSFT support.
The first guy who covered the call was clueless, trying to follow a script,.. a bad version of Chat Gpt ...
I then asked to be moved to his supervisor, who was clearly a lot more technical and knowledgeable, but could not offer me a reason as to why hotmail/outlook account emails do not function today apart from suggesting that it could also have something to do with eM Client backend servers.  (although I did mention to him multiple times that all of my other accounts ie_gmails, other pro accounts, etc...) did work perfectly in eM client at the moment.
The only thing that this supervisor suggested to me that perhaps could make sense or offer a solution to our problems, was to move from an IMAP settings (which I currently have for my hotmail in eM Client) to an EXCHANGE SERVER settings (which I believe are different settings altogether).
Although I have had three diff conversations with the support team at eM Client today (and every time, it was the same answer, ie, it is MSFT servers f8ck-up and not their fault) I will take it back to them tomorrow suggesting what MSFT mentioned.

PS: here the link I found about the exchange set up:  https://www.emclient.com/em-with-microsoft-exchange
also as for me , my outlook app is working correctly on my android (ie i'm getting all my incoming HOTMAIL emails) however I m using the MSFT Outlook mobile app for that.
