Can you create a .PST file in Outlook Web Access?

SearchExchange.com expert Brad Dinerman offers an alternative to creating .PST files in Outlook Web Access, since it is unsupported if users are not connected to the Exchange server through Microsoft Outlook.

I'm in a company whose head office is in another country. I have an ID on Outlook Web Access (OWA) that is around 80 MB and almost full. The system administrator emailed me that I should make a personal .PST file. I don't know how to do this in OWA. Can you help me?

Unfortunately, Outlook Web Access does not support the use of .PST files. To archive messages into a .PST, you...

would need to connect to the Exchange server through Microsoft Outlook.

Perhaps the system administrator can hook you up with a virtual private network (VPN) or Remote Desktop connection through or from which you can launch Microsoft Outlook? Of course, you could always try to slip the administrator a bit extra of his local currency and ask him to raise your quota, but don't tell him that you read it here…


I would like to point out the fact that the quota message is a system generated message, not an actual email from a "system administrator," and the recommendation to store excess mail in a .PST file is a non-configurable message generated by the Exchange server. Obviously this creates confusion.

This is a perfect RPC over HTTP scenario and sound justification for upgrading to Windows Server 2003, Exchange Server 2003 and Outlook 2003. Using RPC over HTTP, Outlook 2003 clients have access to there local .PST files.

Here are some good resources on deploying RPC over HTTP:

There is a third-party product called PSTWay for OWA that allows users to access .PST files through Outlook Web Access. If you have this product, do you still need Microsoft Outlook access in order to create a .PST file… or can this be done in OWA?

PSTWay for OWA only allows you to bind to existing .PSTs. It does not create them for you. Therefore, you will need Microsoft Outlook for that.
