Installing Acrobat - keeps pausing because Outlook keeps reopening itself. How to keep it closed?

[Chris-Has-Questions]

This is more of an Outlook problem than it is an Adobe problem, but it's related to the installation of Acrobat. 

 At my company we use Microsoft 365 with the desktop apps. Acrobat wants Outlook to be closed while it installs. I close Outlook and install Adobe, but Outlook keeps relaunching in the background so it can show New Message notifications and meeting reminders. The icon reappears in the system tray and the Background Apps section of Task Manager. 

I figure there's a service running that I need to stop to keep Outlook from reopening, but I can't figure it out. In the meantime I'm having to babysit these installs and end task on Outlook every time it relaunches itself.

Hi Rothf

Hope you are doing well and sorry for the trouble. As described the Outlook keeps on opening it self when you try to install Acrobat.

Please look at the suggestions provided in the help page https://helpx.adobe.com/x-productkb/global/error-close-following-applications-continue.html and see if that works for you.

Hi Amal,

Thank you for the link but that is what I am doing. Outlook keeps opening even after ending the task in task manager. I just think it's how Microsoft 365 works.
