Outlook / Exchange - sharing a particular inbox subfolder only - get message "unable to expand folder"

Note sure why I always seem to have problems sharing folders within Outlook on a Windows Server 2003 / Windows XP enviroment.

Bascially I have a member of staff, who wants to share one and only one parcular subfolder on the network with another user on the network.

I have mastered sharing the entire mailbox (via active directory) and sometimes I can just get the inbox shared but not other folders.

However in this case I cannot get to share one particular subfodler.
I have added the person as a Delegate and added mail permissions under options -> delegates
then I have gone to the particualr sub folder and given owner permissions to that particular fodler only for the folder I want to share.

But when I user that wants to view the folders I add the sharing users mailbox and then try to expand their folder I get the error message "Unable to expand folder"

When you have a subfolder that you need to share you also need to remember that the user must have permissions to drill down the top level folders to the subfolder so they need some permissions to those upper level folders.

Check out this post where I try to explain this.

OK yes I have played some more around with this. Therefore I have concluded the soltion is to move the fodler that needs to be shared to the top of the email folder hierachy so it is adjacent to the inbox. That way we can share just this folder without having to share the inbox and other fodler above what we want to share. Does that make sense and is this a good way to acheive it?

Thanks again.

Even if you move the folder to the top level i.e. at the same level as the default folders such as Inbox, etc then you still need to provide permissions to the top level of the mailbox i.e. Mailbox - Users Name.

Default folders can be handled differently but user created folders just seem to work this way only.

OK thanks I have found so far in testing that for the very top folder (the one with the username) I only need to give permission at the level the very basic level, therefore I just check "Folder visable"

and this seems to have worked as in the other user can only see the fodler that I want to show them.
Is this what you would expect to happen?

Yes. That's what I mean by some permissions, sorry I thought my article would make it clear you only need to be able to view and open the top level folders so you can view and access the folder you need permissions for.
