By web app, I mean webmail accessed via Firefox or Chrome for (say) Windows 10, not smartphone app. My comment about 3rd party email -- is a 3rd email app called Email - Edison Mail (from the App Store) I set up my mail accounts in the app and everything works as it should. 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.

Hence, the trashing of messages is registering on Gmail. It's just that the contents seem completely disconnected from what I see using webmail. All messages that were trashed in Outlook still appear in All Mail when accessed using webmail, even days later. From what I’m reading, this doesn’t actually appear to be an issue with receiving email, it’s an Outlook screen refresh issue, or possibly (although less likely) an issue with notification settings. 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. Try attacking it from that angle and see what you find.



If the proxy directs requests to a newer IMAP server implementation (f.i Cyrus imapd 3.6.1), the iOS 18 Mail app works as expected, even the requests are handled by the same IMAP server proxy.

For example, if I drag a message from Outlook's All Mail folder to Trash, I see that message disappear from the Inbox folder after a short delay.
