not necessarily. we use Peoplecube's Resource Scheduler for this
functionality, and it has an Outlook Plugin (RSOE). We piloted this
outlook plugin on a few people and didn't see any issues, but when we
rolled it out to all 20,000 employees we found very serious issues, it
would cause calendar issues for about 10% of the user population. We
ended up rolling it back (a difficult operation in itself as
PeopleCube support had no idea how to uninstall this in a proper
fashion) and people have to use the web interface to separately book
meeting rooms (we're looking for a replacement for Resource Scheduler
because we still have problems with the back end application).
I also would like to know other organizations experiences with this
Meeting Room Manager product, preferably the Enterprise version, as
we're looking for a replacement for Resource Scheduler.
