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.

    Glad you found a solution that worked for you!  By chance, would you have any thoughts about what to do on the OSX platform?  My settings are already set to outlook.com (I don't use Office 365).  Thanks, and I understand if you don't know as you/other are likely on a PC/Windows platform.

    I have two different email accounts.  One "@msn.com" and the other "@outlook.com".  I am having the same issue all are reporting on both OSX and iOS platforms with Apple Mail.  But since my @msn.com has never been affected by this issue, I have to assume this is a Microsoft settings issue.

    Others have removed the SSL setting.  I am not very tech savvy with mail applications.  But in doing so, doesn't that diminish email security?

    Jeff IS THE MAN! Did the above and it worked with no issues! My main Office 365 account is nos configured and working on my iPhone. Now trying to figure out the IMAP settings for shared/alias inboxes as those are not working with the same settings.

    Yes, this may help some users. Unfortunately, I have to have the shared/alias boxes working, and they were a pain to set up, so I still need a Microsoft fix/solution ASAP.
