IMAP is not working correctly on Outlook Office365. Error: "User is authenticated but not connected"

Hello

Since a couple of weeks I get the problem that IMAP services are not working correctly.

Problem:

I have a GMail client on an Android phone, and a Thunderbird client. Both using IMAP to reach my emails.

From time to time the IMAP service responds with the error "User is authenticated but not connected" and denies the synchronization of the emails, for around 15-30 minutes. In this time I can not access nor answer my emails from the clients.

I have tried from mobilenet and from fix wifi, but I get the same results. So it is independent from the connection.

I have found some hints that this is due to the "chatty client policy" of the cloud.

However this is not an excuse. I need my two clients for work, and I have a business package.

How can I overcome this problem?

Thank you in advance.

    Hello Galamobs,

    Based on my experience, the white/black lists or rules will not affect it. Under this circumstance, it is recommended to remove the affected account and re-add it to Thunderbird so that the affected account will re-connect to the IMAP server. Note: Remember to backup the data to prevent data loss.

    Regards,

    Rick

    Hello Rick,

    I am using a provided service of Office365 which is the IMAP interface. I am using this interface because it suits my needs the best, across platforms and operating systems.

    As we already seen the test accounts are working fine. So the client can handle the IMAP protocol correctly.

    My account was working fine at the beginning, and never encountered this problem.

    However since the Offce365 blackout it behaves this way. (this is correlation and might not causality)

    Because the client side settings did not changed, and are the same as they are on the test accounts, the only place for difference is the cloud.

    Are there any differences between handling accounts?

    Some kind of white lists, black lists, different rule sets for different account?

    Anything that can be different?

    Regards,

    Robert
