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. In the classic Outlook, I would normally check or adjust these. All default folder will show up as top-level ones and mail will start populating to the Inbox folder. For faster and more reliable delivery, add to your trusted senders list in your email software. Simply enter your email address OR username in order to reset your password.

Chosen solution

I don't see - 'When getting new messages... I checked all 5 of the tabs in this window that expressions is not there. This seems bizarre the email would not populate. The uploading of the old messages to the new account is what caused the problem. I will try the safe starts and experiment with the buttons ans see if it improves.

My accounts in Mail app stopped to sync post update

See the attached picture for the Properties window for a user-created folder. When you right-click one of the folders that doesn't show new mail unless you select it, Properties, is the box 'When getting new messages... It's usually not checked by default for IMAP to minimize network traffic. Subscribing to a folder makes it appear in the Folder Pane, but one might not always want a folder to be synced automatically if it is mainly an archive folder or one that seldom receives new mail.

• The problem can be caused by either improper settings or a damaged send/receive group within Outlook.
• Microsoft, gmail and other popular accounts should sync automatically, but if they don't, I'm inclined to think it's due to the VPN or a security/antivirus app that is scanning the TB profile folder.
• I checked on web mail here it is.one account is configured on two computers, one is configured with POP & second is IMAP.
• 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.
• Everything works great for the most part, except with our IMAP users.
• The issue persists with PC connected directly to the internet with no router or firewall in between.

I did see a response from a MS person that said it was working as intended, that it wouldn’t refresh the folder until it was selected. Although that seems like a load of BS, but could just be a con to try to migrate people to exchange at a higher cost. I know that sometimes when doing it, it can take a moment for the rest of the folders to kick back in. Also then you can’t make folders under the Inbox folder, you have to make it in a different folder and drag it out. Mohit is a Microsoft Certified expert for all things Microsoft.

IMAP folder sync issue in the new Outlook (moved emails not syncing to webmail)

If I click off of inbox and down to sent item, then click back on inbox, all of the new mail will populate. The problem can be caused by either improper settings or a damaged send/receive group within Outlook. At first, I was thinking it may be an issue with certificates, but it's not... I went to a bunch of online TLS tests and the mail server is fine and the certificates are trusted... So only wait when some "smarties" from apple IT solve problem in app ... Apple programmers use no CD/CI - simple sometimes update by "sales-manager requests", and without any critical-bug-checks ...



These methods help you in the synchronization process. If this does not work, you can contact your email provider. After that, it is also important to secure your IMAP folder to prevent this issue from happening in the future. So, properly follow the above steps and backup your data from IMAP folders. I am aware of the difference between Gmail's labels vs. Outlook's folders, but I would expect that Gmail does what is necessary to make the folders appear correct over the IMAP connection to Outlook. 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.
