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.

    This has been happening on my iPhone for the past several days, too.  My email is actually working, but this error message keeps popping up. When I click on the DETAILS buttons I see the certificate for outlook.com Issued by DigiCert Cloud Services CA-1 is "Not Trusted" "Expires 10/7/21 6:00am". Under "More Details" the validity period is 10/6/2020 6pm through 10/7/2021 6am.  Lots more information there...someone please tell me what bits are needed.

    This is exactly what I am getting.  Definitely system wide on the Microsoft side.

    I finished up on the phone with Microsoft.  What they had me do was remove the account from the iPhone in Settings >> Passwords and Accounts >> that email account.  I selected to delete the account, it spun for a few minutes and then I decided to reboot the phone.  I went back to the same settings page.  The account was still there.  I disabled the "Mail" item for that account which is located right about "Notes".  This has stopped the pop up messages so far.  I think the error might be related to the built in mail app and not necessarily the Outlook iPhone app.  Since I use the Outlook app for mail and calendar, this is good enough for me so far.

    With respect, I beg to differ with those suggesting this is a “Microsoft problem.” I am suddenly seeing this message on both iOS and OS X devices. I do connect with an Outlook server for a paid management email account service on Microsoft’s Exchange platform. My email address is related to a domain I own and DNS is set up to direct mail for my own account on this domain to the Exchange server. I also had problems related to another email account (entered into the internet account settings on my iOS and OS X devices (in system preferences) which sits on mail servers provided by another hosting service (NetworkSolutions) for another personal, though unrelated, domain I own. NetworkSolutions warned me and issued instructions to deal with “trust” problems with the certificate for their server, related to protocols instituted and managed by Apple with regard to such certificate trust matters. I am not technical, but in layman’s terms, I understand the problem to be one of Apple tightening the security screws another turn or two... I lay the blame on them.

    Good luck getting them to correct it. Incidentally, following NetworkSolution’s protocol for dealing with this, which involved manually installing the certificate from them directly into the repository for such files accessible through the Mac OS X Keychain Access utility.

    I only hope that Microsoft will be faster to respond than I expect Apple to do so, to straighten this true pain in the **** out with a workaround.
