I've been using Outlook for Mac (version you can download as of today from office.com, which is version 16.37) to manage my email from Gmail (G Suite account).
Mac is operating on Catalina 10.15.5
A couple of days ago I noticed some missing emails in Outlook, so I wanted to re-sync. Based on online research, I deleted the Gmail account within Outlook and then re-added. Many emails synced, but not all. I tried this several times.
I also tried things like: re-booting Mac, deleting Office entirely from Mac and then re-downloading and re-installing. Still, when I add the Gmail account I get an incomplete sync.
IMAP is enabled in Gmail.
Does anyone know why this happens and if there are more things to try?
