Mail Keeps Quitting

I'm using Sierra, 10.12.6. Mail keeps quitting. I reinstalled the OS from the Recovery Drive. I thought that would solve the problem. It didn't. I used Time Machine and tried to replace the Mail app with a version on Time Machine that was several months old. I got the message that "Mail can't be modified or replaced because it's needed by the Mac OS." Or something similar to that.

Is it possible to use another app, say from the App Store? But, I'd only want to do this if I could still use the emails I've saved, and the Contacts, etc.

Otherwise, is there a way to repair the Mail app?

Mac Pro, macOS 10.12

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

If still no good Disconnect from the Internet, then start Mail, look for the last rec'd eMail.

Does Mail crash if no internet?

Quit Mail & login to your WebMail in a Browser, if possible delete any later eMails there after the last rec'd one on the Mac.

If you have no POP accounts & they’re all IMAP accounts then in Mail’s Mailbox menu choose Rebuild.

The POP account will lose all the eMails that are not left on the Server. For that to work you'd need to move or copy all your POP eMail & boxes to On My Mac Boxes to preserve them before you rebuild.

I do have one POP account. What happens if I "Rebuild" ? The other accounts are IMAP, I think. They connect with iCloud. Will the POP account be destroyed?
