Yes, both policies are in place.

We have successfully used BitLocker To Go on Windows 7, where regular, non-privileged users were able to turn BitLocker on and off on their removable storage. Now, in Windows Server 2008 R2 (domain attached, no Bitlocker-GPO configured) we see an UAC-icon against a removable drive in BitLocker Control-Panel (see screenshot) and regular users are prompted to provide admin-credentials if they want to manage encryption of that volume. What are we missing here? Thank you in advance!

Which policy would that be? On Win7 there was no particular policy applied. The only two polices we tried (the are applied now) are: "Allow users to apply BitLocker protection on removable data drives" and "Allow users to suspend and decrypt BitLocker protection on removable data drives", but it made no difference.

hi romkuss if you want use bitlocker to go without asking administrator credentials, you should disable the polices for removeable storage device. If you want to use bitlocker to force on bitlocker to go removable storage devices, you can enable the "deny write access to removable drives not protected by bitlocker"

Really no-one? Any MS MVP on the subject? Please...
