after updating three macs to macOS Monterey the apple mail plugin in apple mail extension is no longer visible. Full disk access has been set. User account with administrative rights. Plugin version 4.0.6. DTP version 3.8.2.
When dragging a mail message from Apple Mail to DevonThink (latest versions of both running on latest released version of Monterey) I get the message “Import of 1 messages failed”
I checked I have the the BigSur mail bundle checked. I uninstalled and reinstalled, just in case.
So. It is strange. After I used the menu command the email went to a mail archive database that I created years ago. I then managed to drag three emails to my new archive database. But then dragging stopped working. Even though I was testing with different emails. The menu option also stopped working.
I closed DevonThink , reopened it and tried dragging and dragging failed. I just went back to try the menu option again and it worked, but emails are going to the global inbox. I tried dragging to my new mail archive and that worked. If I drag a dupe I get a message saying it failed (as expected). If I drag to the inbox It worked. Now I have managed to drag 20 emails, to a different location and they all went through.
It is not from a free service like Yahoo or Gmail. This is email accessible by Apple Mail on Monterey. I just tried to drag 18K emails in, since I had good luck with dragging once this morning, but it failed.
