Microsoft Dynamics GP crashes sending emails using MAPI

Microsoft Dynamics GPOn my Microsoft Dynamics GP demo environment I have Office Professional Plus 2019 installed and Dynamics GP configured for MAPI integration for the sending of emails (I sometimes have my demo environment used when I don’t have an Internet connection so have a hMaiLServer installed for emails instead of relying on the company Exchange). I got caught doing a demo last week when sending an email, Microsoft Dynamics GP crashed whenever I did anything involving integration with email.

I first encountered the crashes when trying to email a creditor remittance, but soon found that even trying to open the Email Settings window did the same thing; in fact any window which tries to connect with Outlook, caused Dynamics GP to crash. I did some investigation and repairs of Office, as well as rolling back a version or two to see if that resolved the problem. Unfortunately it didn’t resolve the problem so I opted to remove and reinstall Microsoft Office from the original media which I know had worked. And it worked again; the rollbacks should have worked, but I may ot have rolled back far enough.

As this old version worked fine, I have disabled automatic updates of Office to make sure I don’t have problems again.
