I'm unable to integrate office 365 with Service Desk Plus Cloud.

In setup, Channels, Email, Email Integration, Office 365, configure.

I login to office 365, then I get this error

"{"error":"Error while adding account : Unable to get SMTP email"}

We have verified that the UPN and email have the same address. We have verified that SMTP is enabled. In any case we have deactivated it and tested it again. Also, we have had this error since Wednesday. The day before it was working correctly. It has also been verified that the password is correct, is there any solution to this?
