Full cleanup of ALL accounts is not a solution(and re-add even helps not). I also noticed that some IMAP settings — like the root folder path (e.g. "INBOX") — are not available in the new Outlook, which makes troubleshooting more difficult.

I’ve tried repairing the data file, removing and re-adding the account, rebooting, re-installing Outlook/Office, running SFC/DISM, all to no avail. Their webmail works fine, and when this account is added to the Windows Mail app, everything works perfectly. One word of warning - you shouldn’t set that interval to more often than maybe every 10 minutes, every 5 would be the absolutel minimum I’d set. If you set too often you run the risk that Outlook could start the next download before finishing the previous download and that could cause duplicate messages and other possible issues.

• I checked on web mail here it is.one account is configured on two computers, one is configured with POP & second is IMAP.
• If you can go to another folder then right back to Inbox and suddenly see 100 new messages, they were there all along, they didn’t just magically appear in that second it took to switch back and forth.
• One other thing I would check for is corrupted OST files.
• Decided to just try completely removing my Gmail account, the one that wasn’t syncing with the Mail App after the iOS 18 update.
