Multiple users here have this same problem that whenever they open a
particular Excel file, it gives them a "Send Report Error." Weird thing
about it is it doesnt happen
in all their Excel files, only happens to some of them. Also tried opening
the very same file/s they are having problems with on my machine and it
worked
fine.
Details:
Files are saved in a network folder
Files are under 50MB size (varies)
Files have Macros imbedded
Files have links

I have patched Office (SP2), updated Acrobat Reader, updated signatures,
uninstalled/reinstalled Office, and
done all the possible troubleshooting on these machines but still error
occurs. Also tried the following links but didnt resolve my issue:
