My iPhone “Cannot Verify Server Identity”! Here’s The Real Fix.

You want to send an email to your friend, but you’re receiving a strange notification. The pop-up says that the Mail app cannot verify the identity of the mail server you’re trying to connect to. In this article, I’ll explain why your iPhone “cannot verify server identity” and show you how to fix this problem for good!

What To Do When Your iPhone “Cannot Verify Server Identity”

  1. Restart Your iPhone

    If you receive an alert saying that your iPhone “cannot verify server identity”, the first thing to do is restart your iPhone. This simple step can occasionally fix a minor software glitch that could be causing this error.

    To restart your iPhone, press and hold the power button until you see slide to power off appear near the top of your iPhone’s display. Use a finger to swipe the red power icon from left to right to turn off your iPhone.

    Wait around a minute, then press and hold the power button again to turn it back on. You can release the button once the Apple logo appears at the center of the display on your iPhone.

  2. Close The Mail App, Then Reopen It

    When the mail app isn’t working properly, try closing out of the app and reopening it. This can occasionally resolve minor problems if the app’s software crashed while you were using it.

    To close out of the Mail app, double-click the Home button, which will open up the App Switcher. Use a finger to swipe up on the Mail app until it no longer appears in the App Switcher.

    close out of mail app

  3. Delete Your Email Account, Then Add The Email Account Again

    Deleting and reentering your email account information resets your email’s server identity certificates, which allow your email account to be verified by the Mail app.  Don’t worry — deleting an email account on your iPhone will not delete your actual email account.

    To delete an email account on your iPhone, open the Settings app and tap Accounts & Passwords. Then, under Accounts, look for the email account you want to delete and tap it. Finally, tap the red Delete Account button at the bottom of the screen, then tap Delete Account again when the confirmation alert appears on your iPhone’s display.

    Next, reenter the account information by opening the Settings app and tapping Accounts & Passwords -> Add Account. Then, select your mail service and enter the information.

    set up your email account again

  4. Reset All Settings

    When you reset all settings, all of the data from the Settings app on your iPhone will be erased. Software issues can be difficult to track down, so we’ll reset all settings to make sure we erase the problem.

    To reset all settings, open up the Settings app, then tap General -> Reset -> Reset All Settings. If you have a passcode or a Restrictions passcode, you’ll be prompted to enter them. Once you do, tap Reset All Settings when the confirmation alert appears at the bottom of your iPhone’s display.

I have had this issue now for three months done all you suggest, have Apple Tech on it but can not fix it and it is driving me nuts. Happens 1 – 3 times a week. Only happens at home but then I do not go out much. I also get Account Errors can not connect to server but then it reverts back almost in seconds and email is fine. I have to do a hard restart several times a week, I have done network resets, forget this wifi, deactivated Apple mail many times since June. This is happening on… Read more »

Hi, I am having the Cannot Verify Server Identity constantly on both my iphone and ipad since June this year. My ipad in the past week has done this almost every day but my iphone twice in 14 days. I have done everything except to reset ALL settings or Factory reset. I have an Apple Technician who wants to now escalate this to engineering but it can not be escalated until I can give them a screen shot of when it happens and get in contact with them within a 12 hour time span. This has been hard because it… Read more »

I find that I simply turn off WiFi, wait a second or two, then turn it back on solves this issue every time.

I believe Apple does this on purpose in updates to get people to upgrade! Did they not get caught once already. Always when new phones come out we see all these glitches in older phones.

I totally agree! Apple tries to force everyone to update. This mail setting changed on its own. Everything was fine a couple days ago, but then the setting changed – and I did NOT do it.

I am unwilling to reset my phone. There has to be a better way. I understand if you call Google 24/7 you can get help.

Simply going into the account settings and turning SSL off fixed the problem for me. I will add that the account was working with SSL until a recent iOS update 😛

I can’t believe Apple hasn’t fixed this, yet. It’s been a problem for years.

I have done wifi resets, hard restarts and deactivated account etc etc the only thing I have not done is a FACTORY RESET as Apple advised not too. I have to try and catch the next message Cannot Verify pop up as I just did a hard restart so when the next one pops up I am to take a screen shot and contact my Apple Case Manager. The only issue is if it happens on a Saturday it is too late by Monday for her to take a log. So it needs to happen in a 12hour or less… Read more »

P.S. As someone else suggested, I would advise people to record or take a screenshot of their account settings before deleting the account because this information can be hard to find.

Thank you! It worked just beautifully. Fortunately I didn’t have to do the last step and reset all of the phone’s settings to see the problem resolved.

You forgot to tell us to take a screen-shot of the existing account before deleting it – now I have to figure out the SMTP settings from first principles.

Got it! And its working again! First try options 1 & 2. If that doesnt work… do not delete your email or reset all your settings… cause that simply sucks. Go into your email account settings and turn on SSL in both your incoming and outgoing mail protocols. Go to Settings, and select Accounts & Passwords. Select your email account, and then scroll down to your OUTGOING MAIL SERVER and click on SMTP. On the next screen, click on the server identified directly below where it says PRIMARY SERVER. A bunch of settings will appear. Turn on the button that… Read more »
