iPad 'Cannot verify server identity' error

Hello Bulletvaldez,

I have the same issue, happened to me in the last 2 days, I did a lot of troubleshooting but no success.

finally, I did solve the error.

just I delete my account from my device then I get access to my account from the browser of the same device and reinstall the account again in the mail outlook...

The error is solved.

You have to delete the account and add again clicking in outlook account instead of other. For example, I have msn account and always clicked “other” to add the msn. I had to delete and click in outlook to add my msn email.

A common "cheat" when you play games like Candy Crush (a screen pops up saying you have to wait some time before you can play again) is to go into settings and move the date one day forward. A similar cheat is to move the date one day forward (or backward) over and over again to receive endless "bonus boosts" which are supposed to be awarded one-per-day. When I do that, I often get the "cannot verify server" message. The solution is always to simply go back into settings and reset the date-time to "automatic". Of course, I can then go back to using the cheats over and over until it pops up again.

This has just started out of nowhere on my wifes iPad with a mail3@gridhost message via wifi (though it also has a cellular connection) but both accounts on the iPad were gMail ones, so it looks like a saved e mail was trying to respond to a source email?

Just deleted both accounts from the iPad and issue resolved, but why it suddenly appeared, that is the big question that no one yet seems to have found an answer for?

Try deleting and re-adding you Microsoft email account. That seems to help.

I deleted my Hotmail and outlook mail accounts from my iPhone 11 and then added them again. This seemed to have cleared the error.

YES!!! YES YES YES YES.

Noticed that hotmail account now is listed as OUTLOOK account.

Deleted the old "hotmail account" on the list of accounts.

I was able to resolve this quickly

settings->mail->accounts->hotmail-> click account name

change imap-mail.outlook.com

to pop3-mail.outlook.com

save and done

Yes, by deleting and then setting up the email again fixed the issue. Apple IOS 14.1 caused the issue for thousands of users, along with the frustration it caused. Programmer ERROR in coding.

This may not be the answer to your problem but I was working on a student's iPad and I finally figured out his date and time was off and was not set to auto update.

This appears to be a Microsoft problem and they are aware and are working to resolve.

Most people just disabled Notifications for Outlook until issues resolved.

Go to settings, mail, accounts and delete any e mail accounts.

switch off and restart to clear the memory and re I still them

Seems like after 11 pages some fix it and some are not. Maybe let me highlight some key takeaways:

1st situation - when you have hotmail or Microsoft mail account in your devices

Solution (1): Goto Setting > Mail > Accounts > Your hotmail or whatever Microsoft accounts > Delete and then reinstall

(note: choose outlook.com when reinstall)

Solution (2): Change the incoming server from smtp to pop

(note: your mails in device may disappear as it is what pop differs from smtp)

Solution (3): Make your hotmail inactive / disable the notification

(personally I doubt if this is a fix)

2nd situation - when you don’t have any hotmail account in your devices

Solution (1): Setting > General > Reset > Reset Network Settings > Reboot

(note: this solution is suggested by Apple help desk)

Solution (2): Goto Setting > Mail > Accounts > Your gmail or whatever mail accounts > Delete and then reinstall

Solution (3): Create a hotmail/outlook.com mail account, add it to your device and let your device update the certificate accordingly. You can remove the mail account afterwards.

Solution (4): Goto iCloud, logout and login again (some says it works but I don’t know the mechanisms)

Lastly, the issue is obviously caused by verification protocol between Apple and Microsoft, thus a permanent fix count on these two parties. Anyway I have filed a bug report via beta program. Let’s see.

Having the same issue, and seems it appeared around the same time as others. Seems to be tied to my "hotmail" account....what a pain! I deleted that mail account, and it has not popped up again, and then tried reinstalling that mail account, which started the "popups" again....ugh

I think I found a fix. I have an iPhone 11 Pro also, and this just started happening today. You can identify which mail account is causing this error message. Mine was an old hotmail account. I deleted the account from my phone, and then I added it back in. That seems to have taken care of the problem, fingers crossed. But so far so good.
