> Outlook "closed improperly" the other day. I can't remember exactly why.

> When I restarted OL, I got the "usual" alert that it had closed improperly,
> that the file would undergo whatever check occurs when that happens, and
> that the system performance may be affected during the check. The lower
> righthand of the screen showed an icon with two gears, and hovering the
> mouse over the icon produced the tip "Data file in progress."
>
> Hours later, when it was time to shut down OL, the file check was apparently
> still in progress.
>
> Now, on restarting OL again, it's still checking.
>
> How long should this take? How can I tell if this is a problem?

> Thanks.
