I haven't seen this issue before, but I would try the following:

Close Outlook. Find and rename the following files: outcmd.dat,
frmcache.dat, extend.dat, *.SRS.

Open Outlook and test to see if the issue has resolved.

Let me know.

I have a weird problem when using Outlook. When ever I click reply on
a message a new Microsoft Excel workbook opens and the worksheet is

would like it to
stop. I would appreciate any suggestions or solutions to this problem.
Thanks,
