I am attempting to use zoho mail as an imap client to add my outlook.com m365 account.  In the m365 exchange admin center i have made sure the imap is enabled.

In zoho mail i go to settings, mail accounts, add account, add imap account, i select "outlook", i enter my email address, click authenticate, i get the microsoft oauth popup, authenticate my account, and then the oauth popup sits there for a few moments, and eventually closes.  Sometimes in the zoh omail app i get a warning "Error while performing operation : 0"

I found some old posts that said you need to have "Authenticated SMTP" enabled, however this is a depreciated feature and not available in my m365 instance.
