I need to be added to this list. This issue has gotten worse. I have been dealing with it for almost a year now. I now have to use taskmanager to kill outlook and the QB application when it locks up, which can be several times per day. Now i have been having to run repairs on my Office application and create a new outlook profile because it is corrupting it. FIX THIS ISSUE. I have the latest versions of QBdesktop 2020 and Outlook 2016 will all applied patches, etc.
