SUMMARY

This article discusses how you can change from using personal folders (.pst) file to using offline folders (.ost) file, and how to create, use, and synchronize offline folders (.ost) file.



MORE INFORMATION
You can create and store .pst files on a hard disk other than your server mailbox. You add .pst files as a service to the user profile, and give it a file name.

To use .ost files, you must change the mail delivery from your .pst file folders to your server mailbox.

Offline Folders
Offline folders (.ost) files are stored on your computer and are available even when the network is down. The default location for the .ost is your current Windows folder. Like personal folders (.pst) files, .ost files can be compacted to save space on your computer.

The difference between an .ost file and a set of .pst files is that the .ost file starts as a mirror image of your folders on the Exchange Server, and works in conjunction with the Exchange Serve during synchronization. A set of .pst files, on the other hand, is simply a storage location on your hard disk or a server other than the Exchange Server.

When you work offline, you can add, delete, and modify the contents of an .ost file exactly as you would with a folder on a server. For example, you can change and move items in your offline Inbox, send messages that are placed in your offline Outbox, and read your offline public folders. In the meantime, information on the server is still processing. You continue to receive new messages in your mailbox while other users can add, delete, and change items in public folders. However, you are not be aware of these changes on the server until you connect to the network.

When you need to update the contents of the .ost file and its corresponding server folder so that they are identical, you synchronize the folders, and then continue to work offline. In Outlook 2002, this is done through Send/Receive Groups. Synchronization connects to the server through Dial-Up Networking, copy the changes made in each folder to the other folder, and then disconnect. An item that you delete from either the .ost file or the corresponding server folder is deleted from both after synchronization.

How to Create an Offline Folder File for Exchange Server
NOTE: You must be connected to the Exchange Server for the initial creation and synchronization of the .ost file.

Use the following steps to create an .ost file:
 * 1) On the Tools menu, click E-mail Accounts, click View or change existing mail accounts, and then click Next.
 * 2) In the Outlook processes email for these accounts in the following order box, click Microsoft Exchange Server, and then click Change.
 * 3) Click More Settings.
 * 4) On the Advanced tab, click Offline Folder File Settings.
 * 5) In the File box, type the path to the file that you want to use as the .ost, file. The default name is Outlook.ost. If this file already exists, you are prompted for a new name.

All of the standard Outlook folders (Inbox, Outbox, Deleted Items, Sent Items, Calendar, Contacts, Journal, Notes, and Tasks) on the Exchange Server are now ready for offline use.
