Merge Tools did not work for me or else I didn't know how to use it. I have an excel sheet that has one sheet, first row titles. The option "many to one" had an error - calculation error? Don't remember. But I deleted it because it also prevented Word
from remembering that I had associated a data source from this computer.
Here's what's happening on my end, and maybe someone can make a recommendation that doesn't involve altering my computer.
I formerly was able to do merge documents until I edited my options to NOT send right away. Which I needed because I have to edit the emails individually before they go out. NOW email mail merge doesn't work unless I send as plain text, which I can't. HELP!
