Hi Johnny,
I have checkes these points and they are all ok.
Also I have created a new global admin account with the onmicrosoft.com suffix but the problem is still there..
the file version is: 1.0.7020.0
It should be the latest version I think. I have downloaded it from Office365 two days ago. And yes the Dirsync is installed on a DC.
I hope you can help me out with this.
Regards,
Yannick
