Hello,

This is one of those 'so called' nifty features that using Outlook with Exchange allows...
Likely you just need to change its settings or turn it off completly if you don't want it...

To get to the Free/Busy settings
- go to 'tools' menu and select 'options'.
- from 'preferances' tab select 'calander options'
- from this window select 'Free/busy options' (normally in lower left corner)

Play with those settings there and you should be able to stop the error message.

-Enjoy
