performance issues in office 2007 on windows 2012 R2 Terminal

HI,

I have a new VM Windows 2012 R2 (Vmware) and Office 2007.

Users are connected through RDP and through Cockpit.

using both methods users complains about performance issues when working with outlook (Ex. moving from one email to another can take 20-30 Sec.) also working with Word can be slow.

I have windows 2003 with office 2003 terminal server working with no issues on the same Virtual infrastructure.

Any Ideas?

Regards,
