Hi,
I've been working for a couple of days on this issue and no joy. Please see the attachment, the error that I get is this:

C:\Documents and Settings...Outlook.ost cannont be accessed.
You must connect to Microsoft Exchange at least once before you can
use your offline folder file.

When physically connected to the network I'm able to stored a copy of my mailbox in the proper .ost , but when testing the offilne feature I get the same error as showed in the attachment. I even changed the location of the .ost to my documents and received the same outcome. I've recreated the outlook profile and the entire profile several times with no luck and removed and reinstalled office, and check permissions.

However,, I'm able to access my mailbox with no problem when accessing it over my VPN connection or with of course being physically connected to my network.

I followed this link to setup cache: http://office.microsoft.com/en-us/outlook-help/turn-on-or-off-cached-exchange-mode-HP001232935.aspx#BM5  but no joy.

One thing I did notice I was awkward, I tried to repair the .ost going to c::\Program Files\Common Files\System\Mapi\1033\scanost.exe but the scanost.exe was not there even after changing the settings to show hidden folders.

Please advice, Thank you

You are actually connecting the client in an online fashion initially to configure the local mailbox and cache, right? Once you've done that you have problems opening outlook while not connected to the exchange server? Are you trying to connect with RPC over HTTP? Is your cert self signed or trusted. If it's self signed you need to install the cert in your Trusted Root CAs.

You will need to connect at least once with cache mode and the caching needs to be complete before you can have offline access.

I connected to the exchange successfully and my cache exchange mode completed successfully as well. I'm not trying to connect to the wxchane at all when I don't have a connection. I'm just trying to open outlook and that is when I get the error. If I'm not wrong, outlook should be able to open up with no problem an work offline as intended.

Is your remote network the same subnet as your private office network? If so, did you hard code the IP of your exchange server in your hosts file? I know a lot of poeple do that when they work behind a VPN because of DNS/NetBT resolution issues. I'm just wondering if the client is trying to connect to a valid IP address on your remote network thinking that it's the exchange server. Because the IP is reachable, but exchange services are obviously not reachable, it might cause things to error. here's a test, can you try and disconnect the system in question from any network, wired or wireless, and see if you're able to open Outlook offline?

Mgortega,

That is when I'm having the problem. When I'm completely offline (no VPN, wireless or physically connected to my network) when trying to open outlook I get the error showed in the attachment. Outlook works properly when connected either physically connected or when using the VPN connection.

That is odd. You fully patched? Office SP2?

I don't have the laptop with me right now, but I know that is XP Pro SP3. I'm not sure if there is any updates for Office 2007 itself. I hope this helps!

Office 2007 is currently at SP2. If you don't have it installed you may try that.

So when you try to open Outlook when you knowingly have no connection to exchange do you get a prompt to retry or work offline or cancel? Do you get any prompt at all?

No retry.. Just Connect, work offline or cancel. Which is fine, but when I click work offline that when I get that error. Just to remind you, I'm logging in with a cache account and when trying to launch Outlook offline that is where I'm having the issue.

I don't need any connectivity, I just need to be able to open Outlook offline. This is such a big off an issue that my entire IT department is getting together to see what else could be done.

If anyone has any other inputs, please advice. Thank you for the help...

Thank you mgortega, but I just found the fix for this issue. In my domain we use folder redirection and that was preventing the proper use of Outlook. Created a seperated OU for this computer and apply the proper GPO and everything seems to work now. Thank you for your efforts

What kind of redirection? "My doc" redirection? Were you storing the OST in a folder that was actually being redirected?

You do realize that Folder Redirection completely trumps the whole principal of keeping a "cached" copy of your mailbox on the local drive, right?

You shouldn't redirect the folder or place the OST in a folder that is redirected. There is no benefit of redirecting your OST. It's simply a local cached copy of exchange and is there to enhance the performance of outlook and provide access to your mailbox in offline mode. By storing the OST on the server you essentially remove both of those benefits.
