Due to the several tests I have to perform, I use different users and tenants and in different browsers. Every time I change one of these and I open Word or Excel files the Collaboration for Microsoft is being activated and I got this message: 
It is quite annoying, above all during a demo. Somebody knows, if there is any service or something that I can activate/deactivate in order to avoid this Collaboration for Microsoft activation?

I guess that if I uninstall it, I won't have anymore this issue, but this is not a solution.

Currently I have to perform the Exit of the app, but always ends up opening a new session and then I have to exit again...
I have also thought on deactivating the plugin in Ms Office apps, but this requires to deactivate 3DEXPERIENCE in Excel and Word and so on... and I was hoping for something more general. Thank you.
