iPad 'Cannot verify server identity' error

How do I fix this extremely annoying error message? Sending and receiving mail does not seem to be affected, but starting yesterday for no reason this message keepspopping up. I’ve rebooted to no avail.

As ridiculous as this sounds, the only real fix I have found to work is to delete the offending email account from your iPhone and the add it back. That seems to clear it.


You need your username and password to add your account, so be sure you have it before you delete it!


When you are adding the account, there will be a list of accounts, including Gmail, AOL and Outlook.


Even if your email account is an @live.com email address, instead of @outlook.com, choose Outlook.com.


After 30 minutes the message had not shown up again.


If I am correct, the account settings are changed from an imap to pop3. It doesn't matter to me HOW I get my emails, as long as I get them securely!


Good luck!

I’ve been so annoyed by this problem the last few days like everyone else here. I wanted to respond to you because I too am technically challenged ;) Hopefully this will work for everyone. I did the turn off/turn on again and nothing. After reading some of these answers about deleting the email account (which I was afraid to do) I was successful with the following:

go to Settings, then Notifications, then Outlook (that was my message), go to Notification Grouping and turn “off”. It’s been a while and so far so good.

Hope this helps. Good luck everyone!

While it doesn’t fix the root cause you can at least get the error to pop up less often by changing the push settings for the affected mail accounts. If you change it to push email once an hour you only ge the error every hour. If you set it to fetch you only get it when you manually refresh the inbox’s.

this will not fix the issue but removes the annoying pop up for the most part

Don’t forget to also submit this feedback to Microsoft. They need to either issue a new certificate or renew the expired one.


I took a screenshot of the expired certificate (when the error popped up, I clicked Details). Then, I opened my Outlook app, clicked on my pic to open the left menu options area then went to the Settings icon at the bottom. Clicked on the Help and Feedback and loaded my screenshot and a message asking them to help.


Maybe if enough of us complain they will do their jobs. Users nor Apple can update or issue Microsoft’s security certificate BUT I am disappointed in Apple if they haven’t contacted Microsoft on our behalf to push them to do something about this.

Ok so in settings under mail I deleted hotmail account. Then in the browser Google hotmail then log in and log out. Then back in settings go to Mail add account enter your details then select add. It’ll give a message can’t verify server identity. Select details, hit trust then it checks off your information. I also selected the notes option in there as well.

Not really. I haven’t tried deleting the account & adding it back in yet, but that will be my next step. There have been some helpful comments here. With such an apparently widespread problem, I’m surprised there is no confirmed protocol to fix it.

I opened a ticket with Microsoft however they still haven’t figured out I’m using an ipad (though it was stated in the ticket) so will doubtless I’ll get no help there for awhile, if ever. I actually dont think it’s their problem since we all have no problem sending and receiving mail.

I was having this same issue as others, and I saw that some resolved this issue by deleting and reinstalling their email accounts on their Iphones/Ipads. I have fixed similar issues in the past just by changing my settings first. So I tried that first and so far it seems to have worked, and I haven't received any pop ups since. I turned off and on again 2 different mail settings (so I'm not sure which one resolved the issue). Here is the what I did:

Go to Settings> Mail> Accounts> Hotmail (mine was my hotmail account) > Mail (turn off and then on again). Second (on the same tab) I clicked on Account (under IMAP) and then SMTP (under Outgoing Mail Server) and turned off and on again smtp-mail.outlook.com (under Primary Server). I hope this helps!

Problem was resolved for me by following this info below in italics.


Copied and pasted from FaKre's post:

In my case the problem was, that the new certificate was only issued for outlook.com but I had „imap-mail.outlook.com“ set as incoming mail server.


Go to Settings > Mail > Accounts

select your Microsoft email Account.

then check Account > Host Name

unter INCOMING MAIL SERVER

and change it to outlook.com and save the change.



(On my phone it actually was "Go to Settings > Passwords & Accounts > Mail",... it worked great!)

On iphone, hotmail account would receive but not send out after the latest crap mandatory iphone update to ios 14.1. Everything got hung up in the Outbox.

I changed the settings (in phone's Settings/ Mail section for the hotmail account) to:

Incoming Mail Server Host Name: imap-mail.outlook.com

Outgoing Mail Server: I selected SMTP and entered: "smtp-mail.outlook.com"

So far so good. I hope this helps someone.

When manually changed to Outlook.com, lost outbound email capability. Deleted and reinstalled Outlook as Microsoft Exchange email account and it populated server with “eas.Outlook.com”.


I have tried deleting and installing as Outlook.com email account, same issue.


Waiting for Apple and Microsoft to fix. For now have turned off Outlook notifications but that is not ideal, to me it’s like disabling warning light for your car.

This same “Cannot Verify Server Identity” issue has started happening for me since at least November 20, but the error popping up is for “google.calendar.com” instead of Microsoft. When I click on Details, it cites “captive portal.Nokia.com” as being “Not Trusted.” Are others now experiencing this regarding Google accounts? I’m also confused about what role Nokia plays here because I have no Nokia accounts. Any insight would be very appreciated. Many thanks.

When this happens to me, I know that my automatic date/time settings in settings is unchecked/unactivated. One of the games I play in my iphone gives me one booster item once every 24 hours. I figured out that if I went into settings/general/date & time, unchecked "set automatically" and then moved the day of the month back one day repeatedly, I could then go back to my game and it would have reset that daily feature so I could get another bonus booster piece without having to wait 24 hours. And I could keep going back to that date/time setting over and over again and stockpile a new booster pieces endlessly. But at some point while turning back the date, I would start getting the "identity of "imap . . . " message. This was easily fixed by simply going back into the same settings and re-activating the "set [date/time] automatically" command. If I wished, I could then uncheck it again and resume gathering game booster pieces until it started showing up again. Works every time.
