Did you upgrade to Office 2016 only to find that your Acrobat XI toolbar disappeared? You are not alone. It seems that each time Microsoft pushes out a new version of Office, Adobe lags behind. This was true for Office 2013 and Office 2010.

Did you upgrade to Office 2016 only to find that your Acrobat XI toolbar disappeared? You are not
alone.
It seems that each time Microsoft pushes out a new version of Office, Adobe lags behind. This was
true for Office 2013 and Office 2010.
Responses posted on Acrobat User Forums are indicating that Adobe will push out a release to fix the
compatibility issues between Office 2016 and Acrobat XI “soon.”According to Microsoft, the
problem is with the PDFMOfficeAddin.dll file.
Assuming Adobe follows through, XI users will not be forced to buy Acrobat DC. Can users count
on Adobe keeping its promise?
Based on past experience, the odds are 50/50. In the case of Office 2010, Adobe never did release a
fix. Instead, version 9 users who wanted Acrobat functionality within Office were required to
purchase Acrobat 10. Thankfully that was not the experience with Office 2013, as Adobe did release
a free update to fix the compatibility issues.
Sincere thanks to a Portland-metro attorney for bringing this compatibility problem to my attention.
