You should really disable it as it doesn't offer an additional level of security anyway. Virus scanners are a known source to cause all sorts of connection issues. When you don't see the message, but Outlook still indicates it is trying to send a message at every send/receive interval, it could be a stuck Read Receipt and then you can use this method to remove it. In most cases you can see the message and you can use these techniques to remove it. When it is truly stuck (for instance because it is too big), this of course will never work. When you have a message stuck in the Outbox, Outlook could end up trying to send that message until it succeeds.

A good rule of thumb is to add about 5 minutes for every 2-3 extra mail accounts until you reach 30 minutes.Īn alternative method would be to set 1-3 “high priority” accounts in a send/receive group which checks for new message every 10 minutes and all the other accounts in a separate send/receive group which checks for new messages every 30 minutes (or even longer) When you have more than 3 accounts I wouldn't recommend to set it shorter than 15 minutes. You shouldn't set the automatic send/receive interval to less than 5 or even 10 minutes. When you set this interval too short, a new auto check will take place before the previous one can finish and thus the send/receive tasks can accumulate so that Outlook is basically stuck in an endless synchronization process. Outlook can automatically check for new messages on a set interval.

Below you'll find some common reasons for it and how to troubleshoot it. Under certain circumstances this process can “hang” and indeed cause your computer to slow down quite a bit. “Synchronizing folders” is the generic term for when Outlook is sending and receiving messages and when (if your mail account type supports it) uploads changes to the mail server. How can I stop this? It's slowing down my computer! Outlook is constantly "synchronizing folders."
