Cannot verify server identity *.edna.ru - how do I get rid of this?

What happens when you click the "Details" on the error popup message (See the Pic below)

Best would be to Delete and Add the email account that is creating the issue.

You may also try changing SSL settings

Settings > Password & Accounts > [Select the Mail account} > [Tape on Account with the email ID} > Advanced > SSL Settings > [Disable]

Click <Account (in Blue)

Click on DONE (in Blue) when exiting in the previous screen

I’m getting the same certificate warning. I was able to grab a screenshot of it.

This exact same message is showing up on my wife's iphone. The details section says: Country or Region RU, State/Providence: Moscow, Organization: GlobalSign nv-sa. Anyway to delete this?
