Act! Crashing with Outlook 2016

Jun 27, 2017 | General


Recent updates from Microsoft have caused problems with the Act! integration with Outlook 2016.  This problem is present in Outlook version 16.0.6965.2058 or later.  (To confirm your version, in Outlook, go to File, then Office Account, then About Outlook.) Note that Microsoft does rolling updates of MS Office.  You may not have yet received this update, but will later this year.


There are multiple symptoms of the problem, including:

  • Act! / Outlook Contacts & Calendar synchronization crashes
  • Act! crashes when clicking on an email address
  • The Email System Setup wizard in Act! does not show Outlook as an option
  • In Event Viewer, you see “The process was terminated due to an unhandled exception” for the Act.Integration.exe application
  • Act.Integration.exe crashes on startup or you get “Act.Integration.exe has stopped working”

We know that Act! users rely heavily on the integration between Act! and Outlook and the good news is that there’s a very simple solution to this problem.  Act! and Microsoft are also working for a long-term fix.


Follow the steps below for affected systems or see for more details and additional troubleshooting steps.

1)      Ensure Act! and all Office applications are closed (Outlook, Word, Excel, PowerPoint, etc.)

2)      Browse to one of the following locations, depending on whether your operating system is 32-bit or 64-bit:

  • 32-bit OS: C:Program FilesActAct for Windows
  • 64-bit OS: C:Program Files (x86)ActAct for Windows

3)      Locate adal.dll, right-click and rename to adal.old

4)      Open Act!, Outlook and test the integration components which were previously failing
