El Cap Mail loop [video]

[Jasonwd]

Hey there.

I only just upgraded to El Capitan because I had some CAD software essential to my job that needed a costly upgrade.

All was fine until I needed to reply to an email in a gmail account.

I composed the mail (reply) hit send and a few seconds later the original message popped back, then the main window came into focus, then the original message, then the main window: loop to infinity.

I managed to open mail preferences and disable all the accounts but even with a totally empty app the message still bounces back and the loop begins.

The Top processes are:
securityd_service
kernel_task
Mail
accountsd
....etc

The console looks something like this:

Any ideas? This is above my pay grade

Well it seems the fix for this is to go to System Preferences>Internet accounts> remove all the accounts and re-add them.

This means that you'll have to download all your mail again, but it solves the looping window problem.
