Today I can’t send Mail items to Omnifocus with the Clip-o-tron plugin, I get the following error.
I have done a restart of the Mac, and tried on different email accounts. I also rebuilt the mailboxes to no avail.
macOS: 12.5 beta (21G5063e)
OF: Pro 3.12.2 (149.17.43)
The OmniFocus Clip-o-Tron was replaced with a built-in Service quite some time ago. You’ll find “OmniFocus 3: Send to Inbox” in the Services menu of many apps (including Mail) and can assign a keyboard shortcut to this Service in the System Preferences > Keyboard.
If the OmniFocus Service doesn’t work as expected, I recommend reaching out to Omni Support. You can email them by choosing Contact Omni from the Help menu in OmniFocus for Mac.
