Question : Public Folder snycing issue

Question about public folders
We are using exchange/outlook 2k7 in cached mode
We are using public folders with contacts. If a new contact is added to the folder it updates correctly.
Under the properties of the public folder address book on the "outlook address book" tab we have the box checked that says "Show this folder as an e-mail address book" so that the public folder is available in the drop down of the GAL.
Does this mean the folder is now apart of the .oab locally?
When a user wants to email a newly added contact to, the contact does not exist - even though it exists in the public folder.

Answer : Public Folder snycing issue

Make the Public Folder available offline if you want that available in an offline mode:

Step 1: Enable caching on Public Folder Favorites
Right click on the root of your mailbox and choose Properties
Click the Advanced& button
Click the Advanced tab
Enable Download Public Folder Favorites 
Confirm the notification, close all open Outlook dialogs and restart Outlook as instructed

Step 2: Add the Public Folder to your Favorites
Browse to the Public Folder you want to cache
Right click on the Public Folder and choose Add to Favorites&
Optionally you can click on the Options>> button to configure how subfolders should be handled
Press OK

Note: be careful of which and how many Public Folders you want to cache as Public Folders can sometimes be very large. Youll download all this data in an ost-file on your hard disk and a really large ost-file could result in poor performance.
