Thank you for your help! I've linked my Gmail account with Pantheon-Mail on the latest Elementary OS. Emails download and I can send them no problem. My problem is that when I press A or archive, nothing happens! The emails don't delete or archive.
I've tried pressing the respective icons as well, to no avail.
My system info is: elementary OS 0.4.1 Loki Linux 4.13.0-32-generic GTK+ 3.18.9
Many thanks!
Try killing your running Pantheon Mail instance and launching it with the --debug option set:
pkill pantheon-mail
pantheon-mail --debug
If you're having the same issue as me, then you should see Pantheon Mail is trying to use the wrong IMAP folders for archiving/trashing mails, and this breaks the UI commands you're trying to use. The Online Accounts dialog doesn't offer a "Gmail" provider option (even though Pantheon Mail has code for handling that explicitly) and thus the configuration for Pantheon Mail ends up being wrong.
I've found a temporary fix -- I haven't yet found a way to persist this configuration change as it is automatically regenerated. Again, make sure Pantheon Mail is not running:
pkill pantheon-mail
Then open the ~/.local/share/pantheon-mail/YOURACCOUNT@gmail.com/geary.ini file, change service_type from OTHER to GMAIL, and save.
Launch Pantheon Mail again and enjoy your archiving/deletion... until the next login.
