The title says ist all. Of course you can tick the box to prevent offline use, however then you will not be able to use Outlook offline at all. Any ideas? When you install Office from CD it's another story. In our Company Office 2010 has been rolled out via RPF files, now they got stuck because performance issues.

If outlook Cached Exchange mode is Off, it should not be creating an ost.
That is unless of course cached exchange mode has been set by Group Policy

If 2010 was just rolled out, make sure SP1 was also rolled out

There are many known performance issues in 2010, which sp1 fixes
