Hello.

Recently I was looking into the activity monitor, I grew a habit doing that to keep an eye on battery usage and all.
I noticed that the Mail.app was using three times the energy and CPU as Safari... and that is very uncommon. Not even when it was syncing all the mails when I got the Macbook it was using that much energy.

So I opened the app and saw that it disconnected all 3 accounts. My iCloud mail which has never happened before and my 2 Exchange accounts which happens from time to time when I have to renew the passwords or when Exchange is somehow slower than the app causing hickups.
But all accounts at once is new.
This happened several times during the last days.
I disabled and enabled the new privacy settings but that changed nothing.

What else could I do? Has someone experienced this issues?
 
I have the same issue with mail using a lot of CPU while doing nothing. This is on a fresh install. No clue what is happening or how to fix it. It randomly happens, sometimes silently crashes.
