Outlook Not Getting new E-mail Unless Restarted

Repair the OST file. Sometimes the OST file becomes corrupt, go to Program Files\Microsoft Office\OFFICE12 and run Scanpst.exe.


Check the Send/Receive settings


In my case, the user has access to multiple mailboxes and was caching all of them. Which seemed to cause problems with immediate updates while the user was using Outlook.

What I did

  1. I went into my user’s account settings to Change

  1. Opened up More Settings

  1. Then went to the Advanced tab and unchecked Download shared folder under the Cached Exchange Mode Settings

This fixed my problem, although I am not sure if this fix is applicable to everyone.

Bear in mind

Cached Exchange Mode stores a local cache of your outlook files and folders on your local machine in an .ost file. This allows for users to use and manipulate their emails even when offline.

Turning this feature off, while it may fix the problem, will prevent users from viewing or using their email while offline. While the Download shared folders options will only do it for the extra mailboxes the user is given permission to in Exchange.

Extra: Shortening the amount of time it caches could also help.
