All versions of Office are not compatible with each other. For example, if a user on Office 2007 creates a conditional or simple mail merge, users on Office 2003 may receive errors when using the merge.

Try each of the following to resolve the issue:

Click Save and Return to EE located under Add-ins in the Word Merge document


Install Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats.


Update all workstations to Microsoft Office 2007.
