Hi,

Once again sincere apologies for emailing here.

My dovecot isn't reading the newly updated e-mails from the mbsync.

I have tried running doveadm -D -v force-resync -u email1@example.com "Inbox/Public/Other Users/user1@example.com"

Plese help if possible. Highly appreciate if someone could help here...
