Sometimes it starts over and sometimes it goes up to 8 minutes. The problem is that in the status box, it shows synchronizing subscribed folders and usually shows about 2 minutes. I'm familiar with all the basics like turning on IMAP in Gmail (which was already on since he's been using the account already with his old computer and Outlook).
I set up a new computer with Outlook 2016/2019 and connect to his existing account in IMAP mode. I have a client using regular email accounts.
