Thunderbird-For 2 days now I don't receive new mail.
Using IMAP to outlook.office365.com and I've stopped getting new mail. I can send mail but not receive. It just times out after a couple of minutes. Any help is appreciated. Settings match microsoft's server names etc. Steve

Do you have the authentication set to OAuth2?

State your antivirus if it's not Windows Security, and VPN if you have one.
Hi. Authentication is set to normal password. Just Windows Security and VPN on or off doesn't change anything.
Change it to OAuth2 for incoming and outgoing (as in the link in my last reply), restart TB, enter the account password in the OAuth window. Disable the VPN if it blocks connections.
Thanks sfhowes. That did it. I guess I missed the announcement of the change with TB, but I heard MS wasn't making the change till Aug. Oh well. Thanks.
Forgot to ask. Can I remove the old imap password entry in TB or will that cause problems?
Yes, the imap and smtp entries can be deleted, leaving the single oauth token.
