iPad 'Cannot verify server identity' error

I have the same problem getting the same message just started today on November 1 I was just wondering if this is a bug or something I have an iPhone 6 plus and I have not even done the new update 14 as of yet. Thanks for the info on how to fix it I really appreciate it

Go to Settings > Scroll down until you see > ( MAIL ) than ( Accounts )

Look for ( Hotmail ) - was my email - (Make sure you know your password before deleting) = Delete It

After it's deleted go back and at the bottom Add Account - (Email address & Password)

Solved my annoying message from returning. Hope this helps.

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!

When I look at the cert in question, it references outlook.com instead of office365.com so I changed my smtp server settings in mail and outlook to outlook.com from outlook.office365.com and it resolves, passes mail, no cert issue. I imagine it would work for imap users who manually configured their servers. Change from imap server imap.office365.com to outlook.com. Looks like Apple maybe requiring a match now.

Hi. I am getting this exact error message. I had outlook in native email app and outlook app. I have since deleted both email accounts and deleted outlook app and I still get this error. This is so annoying. I cannot find anywhere to delete the certificate or anything on my phone related to outlook.

I’m having the same issue on my iPhone 7plus. Just updated to SW ver 14.1 never happened prior to software update. I have tried changing the server settings it may stop the error for a day or so but it will come back again citing the new server setting as the issue. Mail doesn’t seem to be a problem at all. I will open Safari and the error will come up multiple times. Highly doubt it’s a Microsoft issue. It’s extremely annoying.

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.

This is happening to me and my boyfriend as well. Super annoying. Seems like a glitch in an uodate. Hopefully Apple or someone figures this out soon to fix this issue apparently happening to many different people

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

I tried that, along with several other things, and it still won't stop.

Some have suggested turning off the SSL option in the problem email, but I've noticed that said problem email (an Outlook account) doesn't have that option while amy other do. This is ridiculous.

It won’t delete your email permanently. You can always reinstall it on your iPhone or iPad, just make sure you know your username and password for your outlook account.

you can also go to the website www.outlook.com in your internet browser and then put in your username and password and access your email that way, instead of through an app.

I just sought Apple help via “Apple Support” today, the guy studied my issue and suggested the following way:

General > Reset > Reset Network Settings

After reset, reboot your iPhone and send test email to yourself.

it seems working for me. Such prompt not reappear so far.

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.

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.

Like everybody else I have also been having this issue but I think I found the fix. I went into settings, mail, accounts, Hotmail, then turned the toggle off for mail.

So far the problem has not come back
