I've been an Outlook user for quite a long time and never ran into this
before. My pst file is constantly corrupt and I keep having to run scanpst
to fix it. Sometimes I can close Outlook and wait a few minutes and it will
be okay. Other times, I can't open messages, delete messages, or move
messages, unless i run scanpst and then reopen Outlook 2007.

My pst file is 166mb and I have multiple email addresses. I never had an
issue before now and it is happening more frequently. Any ideas what could
be causing this to occur so often? I am running Outlook 2007 on a Vista
machine.

Thanks
