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 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 also have the same issue...but across my Mac OSX, iPhone, and iPads!  Clearly, a Microsoft problem to address.

    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.

    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.

    I am having the same issue.  A co-worker of mine is getting that message on their iPhone.  On a Laptop, I used Edge to navigate to outlook.office365.com and the page will not load.  The Security icon for the site (looks like a padlock when secure in the box to the left of the url address textbox) keeps on alternating between the globe icon and this padlock.  The page will not load eventually.  I tried the same thing with outlook.office.com.  When I cancel the load after a few minutes, I get a page can not be loaded message on the browser with the following details:
