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.

So, here are the solutions you solve the problem of modern authentication troubleshooting the IMAP folder not syncing.

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. This limits the amount of network traffic and improves performance for syncing important folders.

Delete Confirmation

It will synchronize deleted items if I delete an item from my phone, but it just wont receive new ones. IMAP accounts should update automatically on send/receive. Otherwise why even have the ability to auto-sync? If I need to click on each folder to force the sync/download from server then auto sync serves no purpose. When you are accessing Gmail via the web application everything is hosted on Google's cloud servers.

• 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.
• 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.
• 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.
• Ok so my mistake the Properties option is there when right clicking folder - I was only focused on right clicking on the email address to take me to server setting I was not clicking on the actual folder.

I deleted the Apple Mail app from the phone, reinstalled from the App Store. It's just a little bit technical, but we have an IMAP proxy that chooses from some different backend IMAP servers. If the user account ends up on an old IMAP server implementation (in that case f.i. a Cyrus imapd 2.4.17), IMAP Client of iOS 18 Mail app doesn't work.



That’s why, here I am to help you in this situation by providing you with solutions. But, before that, let’s understand the cause of the issue. If I am sitting on my inbox and do a send/receive, no new mail will populate. The send and receive does not error, it looks to complete successfully. Doing a send and receive does not update the mail, and I have played with all kinds of settings in the send and receive groups but nothing seems to work.



Everything works great for the most part, except with our IMAP users. IMAP users are not receiving new email into their inboxes unless they either click off of Inbox and back on, or close outlook and reopen. These are the common reasons why the IMAP folder is not syncing.
