After a minute, it was removed so just went and re-added it and BOOM. One other thing I would check for is corrupted OST files. Turn off cache mode, delete or rename the OST file, and then turn cache mode back on.

To resolve the IMAP issue, I will explain different solutions in the upcoming FixTechGuide fix for stuck folders section of the article. To set up a mail account, we can set the same standard name "mail.mydomain.com" as the incoming and outgoing mail server.

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. But many users run into the problem where their important Outlook sync help from FixTechGuide IMAP folders are not syncing or stop updating.





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.

• This limits the amount of network traffic and improves performance for syncing important folders.
• We only have a handful of people who use the their email across multiple devices at the corporate office.
• Furthermore, when calendar invites are accepted using the Outlook client, they disappear from All Mail and go into the Trash folder, but when using WebMail, they remain in the Inbox.
• These methods help you in the synchronization process.
• Full cleanup of ALL accounts is not a solution(and re-add even helps not).
• 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.
• Look at the mail server settings boxes for password and port settings they’re the ones you need to delete and reapply.
• I went to a bunch of online TLS tests and the mail server is fine and the certificates are trusted...

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.

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.



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.
