Invalid SSL Certificate

[Garyp]

After being idle for a short while, sync with the exchange server fails with the failed ssl certificate message. Opening the account set up and forcing a manal setup with no changes will reset something and the sync works just fine. Using imap on a galaxy s6.

So, your issue is solved now, right?

Exchange? IMAP?

Or maybe the mail provider / cable company in your forum registration email?

If it is Exchange (even if it's IMAP), I'd need to see a debug log (please see below in my signature).

Oh, and if the message is about an SSL certificate *change*, that's the app doing what is expected, tracking SSL cert changes. Please tap the error message (in red below the account), and accept the change.
