Exchange Account not Retrieving Email Regularly

Question

When I first start Mail, it logs in and synchs my Exchange (2007) account fine.  But after that, it never retrieves the mail again.  I have to restart mail to get it to synch again.  What gives?

Answer 1

I wrote this article on tips for trying to rectify this issue of the Outlook 2010 client itself

#2 Usually does it for me.
1.) Verify network connectivity to Exchange from the machine (i.e. try pinging the box) or log into OWA.
2.) Fully Toggle Work Offline Mode.
*This means to Enable Work Offline from the Send/Receive Ribbon, shutting down Outlook (and Lync 201x as well), then launching Outlook, and then disabling Work Offline mode.
3.) Try turning it off and on again.
3.) Visit %UserProfile%\AppData\Local\Microsoft\Outlook and ensure OABs, RoamCache, ~xxxx.OST.TMP or ~xxxx.OST, are not in Read-Only mode, and avoid encrypting this folder (it isn’t Microsoft’s best practices.)
4.) Rebuild the OST by simply renaming the .OST to .OLD or some such, Outlook 2010 and Lync 201x have to be closed, then re-open Outlook 2010. This maybe needed for OST files several GBs in size. It’s very well documented and known to become unstable as size
increases.
5.) Rebuild the email profile itself by utilizing Control Panel\Mail (32-bit).
6.) Attempt a Repair of Office 2010 (Go to Programs and Features, and right click Microsoft Office 2010 click Changes).
7.) Attempt an Uninstall / Re-install of Office 2010 (you may need your product key for this!)
8.) IF you have tried all steps above, a lot of people are completely at a loss. Not me, rebuild the Windows Profile itself. It obviously has some corruption in the registry, temp cache, cache, effective credentials and what not.
9.) When all else fails, reformat! This is the equivalent to a nuclear strike though, so use the right tool for the right job.
