SharePoint 2013 - Office 365 Pro Plus - groove.exe goes wild - MS support needed

[Stephan G]

Hi everyone,

i already posted at technet forums Link. But now i want to open up a "Software assurance case" at Microsoft. The support page does not take my contract ID and SA ID. (i did that before and it worked).

So i want to call MS Commerical support. BUT NO ONE ANSWERS ANY PHONE!! the support number in germany is wrong and the numbers in switzerland and austria respond: "Our office is closed"

Can anyone tell me a number from MS that i can call to get the support i paid for?

These numbers are crap https://support.microsoft.com/en-us/help/4073697/microsoft-commercial-support

It's such a simple task and it already costs me about an hour.

Finally got someone on the phone. We now created a paid MS support case as this would be the only possibility.

I found this article that describes what we want to do

The groove client that is included in Office 365 Pro Plus 1808 is the Office 2016 groove client or did i get something wrong? Do i have to install the groove client somehow manually?
