Apple Mail import fails

It seems to be a hit or miss. A few days ago I dragged and dropped from Apple Mail into a Group in DTP, it worked with no issue.

Today I tried copying a short thread (also tried individually) and received error messages. “Import of 2 messages failed”, then “Not Connected to Internet. CK ErrorDomain 3” (yet I am connected, as I type this and read articles on the web). They might be unrelated, as the latter message keeps repeating.

I don’t want to do any bulk email processing as I’ve seen some like to do, just import a few specific emails to DTP.

I tried quitting and restarting both apps, no change.

Sonoma 14.7.1 on a M3 MacBook Pro.

The messages are unrelated.

Re: Apple Mail, see if this helps…

Thanks.

Unfortunately, that didn’t help.

Does DEVONthink have its Automation requests allowed in System Settings > Privacy & Security?

Also, you can try dragging and dropping to the Finder, then into DEVONthink to see if that works.

That worked! Thank you!

The Automation setting or drop to Finder then DEVONthink?

Dragging to the Finder, then into DTP is what worked for me.

My System Privacy & Security preference settings allow automation with DTP and Mail, Finder, web browser, Outlook and Daylite.

I too have been running into this issue recently. Dragging and dropping emails straight from MacOS mail will work for a while and then stop. Haven’t worked out why.

I did the above suggested Mailbox rebuild and that didn’t seem to make any difference. (Caveat: it is a huge mailbox and I don’t see a progress bar for how long it should take so that also might still be an issue)
I moved on to @BLUEFROGs suggestion of using the Finder as a middle step on this process. It worked on some small test groups but then it too stopped working. I was able to track it down to two emails in a thread that had .txt files as attachments. Those two emails wouldn’t even show up when dragged to the desktop.
With this knowledge I went back to DT and I could drag the emails without attachments directly into DT without doing the Finder step. The ones with attachments wouldn’t work at all, to finder or DT.

Yet, sometimes it works, attachments or not.

EDIT/ADDENDUM
There’s definitely a lag in how Mail processes some messages. When I returned to the Finder folder a while after I was working on this, many copies of the emails I had tried to drag into the folder were there now. So it was working in some form BTS but with no way of knowing progress or level of success.
