Exchange 2010 Global Address Book not updating

With the GAL you always got to find out if it is an issue with GAL or Outlook, often time it is outlook.  If you open up OWA you will see a direct connection into the exchange server and from there see if the address book is updated.  

On outlook make sure you send and recieve all items (F9 i think works too)

OWA see's the new addresses...  My Outlook and many others are not updating.. I tried F9, send/receive, and the update of address book too..  What else should I try?

I have seen the cached mode do this. Try (un)checking it.

The global address book properties show the below information.  I tried everything suggested except disabling cache mode and re-enabling.  That is not a good solution for I have too many users with these symptoms with huge mailboxes.  I'm currently downloading the addresss book without the check mark stating to download since last send/receiving.  I'm hoping this will force it.  

C:\Users\myusername\AppData\Local\Microsoft\Outlook\Offline Address Books\a02badd4-9cad-46b9-a602-6f477ca0306b\

\Global Address List

Is this a 1 server or multi exchange server?  I have seen IIS have funcky settings with multiple servers are installed.

try to delete the folder location above.  As for the enable disable cache, if that fixes you can do it through GPO is you have that setup.

I deleted every item in 'C:\Users\myusername\AppData\Local\Microsoft\Outlook\Offline Address Books' and it now works..  I can easily send these instructions to most users.... The one that aren't capable I'll do via admin share from my desk or use a GPO.

Thanks!

As mentioned in my previous post deleting the items in 'C:\Users\myusername\AppData\Local\Microsoft\Outlook\Offline Address Books' fixed it.
