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.

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. I have seen this disparity for years across different Outlook client versions and Windows versions. I also posted on Outlook stuck updating folders solution the Gmail subreddit about a year ago.

I have several email accounts / IMAP set-up. So looking at my tree of fix Outlook after Windows update issues email accounts one inbox might have 10 mail total and 3 unread form earlier. It's not until I click on that folder I will then see the 10 and 3 and two second later it will sync and new ones will populate. The issue is; just looking at my email accounts and the numbers shown next to the folders I cant tell if there is new mail or not until I click on them.

Chosen solution

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.

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 disable faulty add-ins in Outlook IMAP folders are not syncing or stop updating.

• 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.
• These methods help you in the synchronization process.
• Full cleanup of ALL accounts is not a solution(and re-add even helps not).
• Look at the mail server settings boxes for password and port settings they’re the ones you need to delete and reapply.
• 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.

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)

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.



We only have a handful of people who use the their email across multiple devices at the corporate office. Just a question - why not look at office 365? Mailbox only support is like $6 a month or less, and it is proper exchange, enabling better syncing etc. You should look at your Outlook desktop client settings to review the default synchronization schedule and tweak anything you can to get it to poll Google's IMAP servers more frequently. I access the IMAP servers from 3 different machines, and they all see the changes from each other. The problem is that the some changes are not reflected in the Gmail web app.
