After installing Access 2016 all Office 2013 mail merges will crash when selecting or creating a list.
Reinstalling Office 2013 has no effect. Uninstalling both Access 2016 and Office 2013 and reinstalling Office 2013 will allow mail merges to work but once Access 2016 is installed it will crash on mail merge.
I see someone has had similar issues with Office 2010 and Access 2016. https://social.technet.microsoft.com/Forums/lync/en-US/d93ff4cf-0578-48eb-84b9-c92617f483e3/office-2010-mail-merge-stops-working-after-access-2016-install?forum=officeitproprevious
Any ideas?
