Excel 2002 files posted in Outlook do not open when attachment is
double clicked. My computer uses Excel 2000. Does the sender need
to convert files to 2000 files
This sounds like an issue with the Outlook Secure Temporary Folder. Try
this:
Close Outlook. Open a command line window. Enter these commands:
cd %UserProfile%\Local Settings\Temporary Internet Files
dir /a
Look for a folder whose name starts with OLK. Let's assume you find OLK1A.
Enter:
rmdir /q /s OLK1A
exit
Now, in IE, click Tools>Internet Options. Click Delete Files and select
"Delete all offline content" and click OK. Restart Outlook. See if your
Excel attachments will open.
