We are evaluating Windows 7 and Office 2010 in a secure environment and have a strange issue when saving opened Office attachments from Outlook 2010.
If an Office (Word, Excel or Powerpoint) file is opened from a received email within Outlook 2010 and a user then attempts to save, they are presented with a restriction error message as below:
This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.
Upon clicking OK, they are then presented with a Save As dialogue box in the correct location (i.e. their redirected Home Drive location on a network share).
We block any access to the C:\ drive (or any local drives other than the optical drive) and the users have a roaming non-cached profile.
The OutlookSecureTempFolder value in the registry is C:\Users\%username%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\RANDOMSTRING\
I tried altering this to a network location which I knew the user would have write access over, but Outlook just overwrote my custom value with a new one of its own.
I ran ProcMon and determined that the machine is getting ACCESS_DENIED when trying to create files in that location.
Any ideas?
