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 figured out why I was getting this same message. The offending email was my old hotmail.com address. Either delete it or switch it to inactive on your iPhone or iPad and the message will go away. If you still use that email, delete it from your device then re-add it. The correct server settings should download when you reinstall that email account, resolving the server error using either POP3 or IMAP protocol.


If you use multiple devices to access the same email account, select IMAP so the messages are left on the host server and are accessible by all your devices. If you only use one device, I recommend using POP3, as it downloads all emails off the host server and the messages only exist on your device after checking for new email.


Please let me know if this fixes your issue!

  1. Go to mail settings
  2. Select your outlook, gmail, hotmail or live email address.
  3. Slide the button to the left to make it inactive, if you don’t have that button, select delete account.
  4. Reinstall the mail settings.

This seems to have worked for me.

How did you figure it out?


Although on my phone (12.4.1) I went like this

Go to Settings > Passwords & Accounts > Mail

select your Microsoft email Account.

then check Account > Host Name

unter INCOMING MAIL SERVER

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

What FaKre posted earlier I pasted here below

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.

Alright so far this has worked. It seems to only be my hotmail account I get this error with.

This is what I did and the annoying pop up had been gone a few hours now. Was getting it about every 30 seconds.. Delete your hotmail account and then add it again as an outlook from the default choices. Still type it in as @hotmail. Just use the default outlook. Hope that helps.

As mentioned by a couple in these comments...the annoying message is, so far just that...an annoying message that can be eliminated by SIMPLY TURNING OFF NOTIFICATIONS for the offending email account. I did that last night on my hotmail account and the message has been gone. Everything works, but no annoying message. PS, it’s not tied to most recent IOS update because I haven’t taken any update for months. It has to be some Microsoft/Apple conflict that will eventually be addressed.

I have noticed that this pop up happens much more frequently when I am on my home wifi. If I turn off my wifi, forcing my iphone 12 Pro to the Verizon network, the errors stop. Last night I manually updated the firmware on my Orbi router and both Orbi satellites (the auto update returned that there was no updated available). I have not had the problem since. Fingers crossed.

Not necessary.... try this....

Ok so I think I figured this out. Was so frustrating. Go to your email information in settings. (Where you can change your password etc) setting-mail-accounts-then pick your email provider and continue on to where you can change your account info. 

I found that my Host name was changed to imap-mail.outlook.com. So I changed it to what it’s supposed to be for my Hotmail. Which was smtp.live.com. 

if you don’t know what your host name is supposed to be then just Google it. That’s how I found out my Hotmail host name. It stopped for now. Hope it stays that way. Good luck!!
