Q: Draft mail had disappeared.

After the Update to Sierra, I have the same problem:

I can see 2 draft mails, but there is all text content vanished.

Only an empty mail attachment (new!) is shown.

How can I restore the text of my draft?

Is there any place in finder, where I can read the content, if I restore it with time machine?

(Full time machine backup is available)

Thanks

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.

Try rebuilding the mailbox.

If that doesn't work, try re-indexing the mailboxes. This can take awhile if you have a lot of mail.

Reindex messages        For El Capitan, try looking in V3.

Reindex messages (2)        See post by Linc Davis

Thanks. This did not bring my draft mails back.

I will now look, if I find them in my timemachine backup, when I'm back at home (should be there? ~/Library/Mail/V3)

You are welcome. Yes, except is Sierra it is V4.

I have Sierra but with the Update from Captain to Sierra the Draft text vanished.

Therefore I will look for V3.

Are Draft Mails there somehow named that I find it?
