Cannot Verify Server Identity. The identity of @outlook.office365.com@ cannot be verified.

I have this message appearing on my iPad every 20 seconds or so.  I use an Office365 exchange account to sync email, contacts and calendar onto the iPad and also use Onedrive for storage along with Word, Excel, Powerpoint etc.

I have had periods of tim when this error message appears, but usually only for 24 hours max.  If it is for a prolonged period, I found that deleting the Exchange account from the iPad and setting it up again often cured the problem.

This time it has been going on for weeks, with no let-up.  I have deleted and set the account up again twice, to no avail.  Please help it's driving me bonkers.

    I belive I found the solution to this.

    On IOS, under Mail > Accounts go to your outlook account settings.

    change outlook.office365.com to just outlook.com

    Then reboot your device.  This worked for me.  I also changed the smtp server to outlook.com

    The issue seems to be that the certificate name is different than the server name we are trying to access.

    I see this on iPhone and iPad, both running MSFT's own Outlook app, not the browser.  Both on my home internet (>100Mbps) and at the office (>50Mbps fiber).

    Notice the other commenter here is seeing it on Windows.

    One might conclude this problem is not explained by the OS, browser or connectivity.  It's a software problem.  I realize intermittently exhibiting software bugs are very hard to fix, but that's what this appears to be.

    Hi Cheyenne_99

    Good day to you.

    From your description, you first can change the network environment to check the result. As far as I know, the unstable network would lead to the verifying failure. Besides, you can also try to disable SSL feature to check if it is workable (Access to Settings> Password&Account> Select the exchange account> Advance>turn off SSL on iPad). Furthermore, you can re-start iPad to check if it works.

    If the issue persists, to provide further assistance, we’d like to know what you use mail app, such as Outlook, Mail, etc. In addition, does the issue appears when you sign your account in other devices?

    Looking forward to your update.

    Regards,

    Joey

    I am receiving the same issue across iOS devices.  I concur that this is a Microsoft issue - nothing else has been changed or modified on my iOS devices.

    I have the same problem. I can change the SLL, but it won’t let me hit ‘done’ to confirm the change. I get a “Cant get to mail, Logins are disabled” error.
