iPad 'Cannot verify server identity' error

I was excited to see that my setting was what you stated and I made the change. I made the change but it keeps changing back.

Did you first delete your account and insert the host name when you set it up?

Had issue since October 25th. iPhone 7 and iPad Pro. Deleted and reinstalled offending Outlook email account 3 times. Checked Date and Time. Reset all settings on iPhone. Went away for periods as long as 12 hours, but it keeps coming back.

The problem must not be Outlook. I don’t have Outlook on my phone! I spent all last weekend on phone with Apple support. They have no idea, but the pop up message did stop... until today. It started again this day- same message about Outlook server identity and certificate.

This worked for me (at least so far!). It’s misleading because the prompt references outlook so I thought that was my offending account. But I looked under each of my email accounts as you note above and it was my msn account. I made the change. The system changed it back. I made it again and it kept it. I then turned the phone on and off snd checked and it has kept the change and no messages so far. Hopefully that sticks! Such an annoying message. Thank you!

Ive been having the same issue. There r days where message is persistent then i wont see it for days. Like today its been reoccurring. I restart phone. Email functions just fine. So ur saying i should log out of email and delete email app?

I am having the same issue - but I don't use Outlook (only Gmail and Google calendar), and I have never reset the date on my iPhone (it's on "set automatically"). I don't know if it matters, but I don't have access to a Wifi network during the day (my work network is quite locked down, and requires a 64-digit password!), so I mostly use LTE. I can't force the message to appear - it seems like it shows up randomly.

Has this been caused from one of the recent updates to iOS? I've only had the issue for the last month or so . . .

This is happening on on my husband’s iPhone 8- it just started happening a couple days ago. His messages are for his Yahoo email AND today is gave him the same certificate message for the OFFER UP App.

I get it whether I am on Wifi or using LTE. I have tried deleting my Gmail account and reinstalling it, and I still get the messages. I have never changed the date on my iPhone, and it is still set to "set automatically." so that is not the issue. I have attached images of the messages below:

How do I turn it off.?

sadly, ever since the 14 ridiculous update one of my devices (my main phone) shows ... it can’t identify... email addresses, websites, everything.

I know it’s about authentication but can’t find anywhere to resolve it.

it does it several hours a day. When it’s doing it, it’s every second or 2, rotating round and round. And stops all other action.

I can’t even figure out a pattern. I have tried apple support- no longer taking calls and could only chat with people that had zero idea how to fix it.

I’m sure it’s this phone because my other phone & devices don’t do it.

if anyone can help I would be greatfull.

This is what happens when people who don't understand POP tell you to delete your account.

Don’t use the suggestion. I did, and now I’ve lost all other folders, only have inbox, and can’t go back.

Finally on page 13 someone has the same issue as me (almost). I don't use Outlook, I use gmail on my iPhone 7+. I too have been getting the same annoying pop ups but they are saying imap.gmail.com and when hitting the detail button I get the same Nokia portal crap as the other user. I too have no clue what Nokia has to do with this nor have I ever had any Nokia product or account. This is across the board and not tied to just Microsoft mail.

Same thing is happening to me. I'm getting the imap.gmail.com pop up over & over and when hitting 'detail' I get the same Nokia portal message you are. So this is really perplexing as the other 14 pages on here are regarding Outlook. Since it's across the board does that relegate the problem to Apple?

This is absolutely maddening! I've been having this problem for a few months and no matter what I do it always returns. I've deleted my email accounts and re-added them several times and disabled all mail notifications, I don't know what to do. When it's happening it makes my phone unusable. I'm still on an iPhone 7 and am looking to upgrade, but I can't justify spending $1,000+ on a device that I can't use because Apple refuses to resolve this problem. Sorry for the rant, I'm just really annoyed.

A number of posts their mail server are not ' Outlook' , mine is one of them.

Obviously contacting Microsoft will not solve ALL the problems.

I deleted the mail account in Setting & recreated it as suggested by a member here, but about 2 weeks later the same error popped up again. Amazed why it was ok for a while.

This error prompt is very disruptive as I am active in Apple Mail app. Don't have this problem before ios 14. Hope that Apple Support experts can give their advice here.
