In Microsoft 2003 Office Outlook with SP2 when using the calendar and trying
to change a recurring appointment I get the following error: "Can't open
this item. The messaging interface has returned an unknown error". If I
select the recurring item and then go to toolbar and delete the item, it does
delete and then gives the following error. "The form cache file frmcache.dat
in not valid". Any help with this problem would be appreciated.
THANKS!
