I have just had to Nuke and pave my iMac. On reinstalling DTPO, all working well, except mail App integration. I have installed the add on and the DTPO prefs confirm this I have also activated for DTPO in the Mail App prefs.
When I choose ‘Add to DevonThinkProOffice’ from mail.apps message menu, it doesn’t work and the log window gives error message Message import can’t connect to mail to get mail message data!
Even if I try to drag and drop the email from mail.app to DTPO inbox, I get the Log message Import of 1 messages failed.
BTW the Blog post says “The next update for DEVONthink Pro Office will be able to install the plugin without that you have to manually grant it full disk access. You’ll only need to enable the plugin manually should you need to reinstall it”
As we are now on 2.11, I would advise that this seems not to have happened - at least in my experience.
This problem still exists under Catalina. Well - sort of. I’ve managed to import a bunch of emails, yet just dragging and dropping the occasional one or two results in the helpful error message “Import of x messages failed” - would be nice to know exactly why? If I had more detail, it would save me the time of posting here!
I’m having similar problem: after updating to Catalina, drag-and-drop from Mail.app into DT3 no longer works. The log window says “Import of 1 messages failed” but that’s not too useful, and the DT UI gives no other indication of failure mode. I followed the instructions here on the forum (e.g. in topic 48735) to clean-install the Mail plugin, and I’ve granted full disk access, to no avail.
The Mail menu item Mail > Add to DEVONthink 3 works, but I want to drag directly into the desired DT group.
This has become a serious impediment to my daily workflow.
The failure seems to be on my side of the application On my iMac I drag & drop my mails like a pro. I only got problems on my macbook. I’ll investigate this case
