    Same 2400 error when running Outlook. Began yesterday after installing updates and rebooting, An office update shows in control panel / programs. Account is an @outlook.com, retail office 2016. Been trying everything I've found online short of uninstalling, nothing working.

    Hi,

    I am receiving the same error code while trying to open outlook.

    But the difference is, i am using outlook app on my laptop (not web) and if i click to my company mail inbox, outlook is working normal (still hotmail not works).

    If i try to connect with hotmail account on web outlook, i can connect. (i can receive hotmail mails from mobile app).

    I am using my personal laptop for business and IT stated that they can not support.

    Below are some screenshot's for my issue.

    I had the same issue, but I managed to fix it.

    On Outlook application, go to File > Office Account, check whether your affected email address is signed in under Account (on the left side).

    If it is not, then try click Switch account and check whether your affected email address account is there.

    Most likely it is not, just add and sign in and it should be fixed.

    You can switch back to your original account after you added the affected email address account.

    Thanks a lot, this worked.

    I have the same problem.

    I have two accounts, but switching back and forth did not help me.
