Like the title states, is it possible to start Outlook 2010 without any PSTs loaded? Alternatively, is there a quick way to close multiple PST files in Outlook 2010?

I am on a PC that has many large PST files open, and I'd like to close most of them, however, closing each one causes a minimum 5-minute delay, and Outlook freezes until then. Of course, this is not ideal, because closing all of them this way will take more than an hour.

Is there a shortcut?

Thanks everyone.


I found an excellent script that solves this issue at the link below.

For anyone else who finds this and tries to use this script, ensure that you modify the "Mailbox -" portion and replace it with your mailbox name, ie. johndoe@company.com.

Removing the comment tags also increases verbosity when run in the command prompt (lets you know which PSTs are being removed).

You can use Outlook Web Access or you can create a new Outlook profile (in control panel, Mail) that points to the same Exchange account. Then use that new Outlook profile (set it up in non-cached mode too) to connect to just the Exchange account if you require the actual Outlook interface to do whatever you are doing.
