Apple Mail keeps losing my email address

This keeps happening to me too. It started a week or so ago. It often happens a couple of times a day and I have to re-insert my email into the Email Address field of the Account Information panel. The way I know it has done it is I open up an email to draft and it shows Hide My Email in the From field, and my signature is missing (clearly because I have no email account selected). I have to physically type the email address back into the Email Address field, as none of my emails are present in the drop down.

Hope there is a fix to this. It's very annoying.

Thank you.

Same here. Been going on for a couple of weeks by now.

Apple keeps loosing reliability in software. Wish they'd put in efforts where really required.

I found that quitting or force-quitting the app and waiting a few minutes before relaunching it, brings the settings back. So, it's not erased from anything. It's the software failing to read the preferences settings properly.

Me too. Very frustrating, and potentially exposes PII info as if I don't notice this, my personal email gets sent through my work email server. And then the recipient sends to my work email (gmail-based) if they reply.

Same thing here. I have tried removing Avast Premium Security, recreating my Outlook and Gmail accounts, but the iCloud account information issue keeps coming back.

Yes, this is definately a problem and I agree, it has been going on for some time. My issue is with my @me iCloud account. A response from Apple would be helpful.

Same problem. Sometimes if you disable then enable the address(es) come back. Anyone know why this is happening?

Yes, same thing here, and like others can happen more than once a day. I haven't seen any answers for this anywhere!
