I have strong evidence supporting that Office16/root/grooveex.dll is related to Adobe CreativeCloud Applications repeatedly crashing when trying to open the windows file picker. It is loaded by teh Adobe application via KERNELBASE.dll. When I rename grooveex.dll, the problem disappears.
I have already found out that grooveex.dll is apparently related to former "Groove Virtual Offices" that has been bought by Microsoft and integrated into Onedrive for Business / Sharepoint.
I'd now like to know the consequences of renaming grooveex.dll, such that it cannot be loaded anymore by Adobe applications and causing them to crash. Will OneDrive for Business / Sharepoint integration still work as expected? What is grooveex.dll for in general? (please, no file.net links and such).
