Every time i start Outlook 2010, a warning box opens stating


"String was not recognized as a valid DateTime"

I have run Scanpst.exe and it said it was fixing some errors...but this message continues.

I guess the warning could be coming from any portion of Outlook but i sort of thought it was most likely from the Calendar.

I think it began shortly after i started gmail's calendar syncing with Outlook.

I tried to delete any new calendar events to no avail.

I have no idea as to how to find the offending item: i would be very happy to delete it. Nor do i have any idea as to how to "repair" the date/time entry...

Any help appreciated.

Windows 7 64 bit; Outlook 2010 --i don't see an About box for its version...

Thanks.
Terry
