How to fix

It is important to follow these instructions in order. Test the Mail app between steps to see if the issue is resolved.

As the error message indicates, there may be some security certificate (SSL) issues with your e-mail provider’s mail server. Another possibility is that your email provider may have made system changes recently and this change is causing this problem.

1. Check with your email service provider (Gmail, Hotmail, Yahoo, AOL, or your Exchange / IT admin) to see if there’s a service outage. Furthermore, check with your service provider to find out if you are using the correct settings.

6. Delete and add your account again. Please note that deleting your account may remove previously downloaded emails. You may want to log in to the email provider’s website if your email provider offers web-based service. If you see all the emails there, then your mails will be redownloaded again when you re-add the account.

Doing so may fix your problem as your current settings may not be correct and corrupt. Here is how:

  • On your iPhone or iPad, tap Settings > Passwords & Accounts.
  • Tap the email account that is problematic (that we will delete).
  • Tap Delete Account.

Now your account is deleted, let’s add your account again. There are two ways to add an email account:

  1. Automatic.
  2. Manual.

What you can do is to try the automatic option first since it is easier and then test your problem if you are still having the problem, and then delete the account and add your account again manually.

Here is how you can add automatically:

  • On your device, tap Settings > Passwords & Accounts.
  • Tap Add Account.
  • Tap your email account (iCloud, Microsoft Exchange, Google, Yahoo, AOL, Outlook, etc).
  • Then follow the onscreen instructions.

And here is you can add your email account manually:

  • Tap Settings > Passwords & Accounts.
  • Tap Add Account.
  • Tap Other.
  • Tap Add Mail Account.
  • And follow the onscreen instructions. Make sure that you enter the email account details correctly. If you are not sure about the details, again you may want to contact your email service provider.

  1. I have this issue since June. I have been battling with Apple top engineers but done everything you have suggested and more. Nothing works. It fixes it for about 10 days and it comes back. I have addressed this with my provider as this started in June after one month of a new modem and NBN being connected thinking maybe the router causing an issue but they say all ok. I am going crazy over this. Only happens when I am at home on WI-FI to my ipad, iphone and on occasions my husbands only. My desktop on ethernet is fine with hotmail just ios devices. No other ios devices that visits my home on a regular basis using my wifi has this issue.

    • *this. like me, you’re probably with Aussie Broadband. I even had to provide their support with the solution. Which works for a month or two… and then it is back again. 🙁

  2. You are amazing! Tried so many sites with supposed remedies after 2 hours on phone with ISP who insisted all was fine. So frustrating.
