@Sanjeev, I have configured mail integration by following that howto. However, it didn't work. Maybe the reason is my Office 365 is enterprise, not home. So I'm realising the problem is on the Office side, and I need to double check Office configuration. Thanks for your support.

I'm getting the following error after issuing "php bin/console uvdesk:refresh-mailbox":

PHP Fatal error: Uncaught ErrorException: Notice: Unknown: Can't open mailbox outlook.office365.com: no such mailbox (errflg=2) in Unknown:0

The account is working, because I have tested it on IMAP client, and I can send mail by issuing "php bin/console swiftmailersend"

UVdesk version is 1.0.12, and PHP version is 7.4 (Ubuntu 20.04).

Have anyone faced it? How can I solve it?
