Outlook 2003 Cache Mode not working

Is it greyed out? Generally cached mode is not enabled on terminal servers.

Otherwise if it is only affecting a specific mailbox then have a look at get-mailbox and get-casmailbox commands on the end put | fl

Then see if they are cachedmode disabled/enabled

Is there any error when enabling Cache Mode ?

thanks your reply!

Yes, it is greyed out. We are using cached mode on win 2k3 terminal servers.
We tried creating profile directly on the Win 2K8 server, that also didn't work.

Is it related to Win 2k8 only?

No, there is no error message.

correction - it does not work on any terminal servers.

is there any tweak to get it to work on TS.

Does Outlook 2010 work?

thanks!

If is on terminal servers, as MegaNuk3: already stated - cached mode does not works on TS.

For Outlook 2010 you maybe find some help here http://www.microsoft.com/downloads/en/details.aspx?FamilyID=776E5D50-D35A-483A-A3E5-99944F4BAE42&displaylang=en

if the server is not a terminal server, it maybe that there is a GPO policy in play for Outlook that is prohibiting Cached mode.  you should be able to check your policy and OU's affected via Group Policy Management on your DC's or Admin systems.  To be honest Office 03 is past main support, and not designed for the latest OS's, you might have better luck with 07 (SP2) or 10 (SP1 will be out this year).

cached mode needs to be selected in 2 places, under the main account on the Exchange server settings and under the Advanced tab of the More Settings page.

Look at the reg key mentioned on the bottom of the solution in this question:

Thanks for the points, are you going to install Outlook 2010 then?
