Free/Busy status does not show up when the special combination of Outlook 2007 & Exchange 2007 are used in CrossOver 8.0. This is a known issue with Outlook 2007, but is usually fixed on most native machines (your co-workers will be fine but you will not). We do have a workaround that has helped many people experiencing this issue...
This is a bit on the technical side (if you have never changed a registry key), so I'll try to give you step by step instructions to get it working properly. Before starting, verify that Outlook 2007 is closed.
On Linux
First, go to Applications-> CrossOver-> Run a Windows Command
Then, select the bottle that Outlook 2007 is in and in the 'Command:' field type:
regedit
Then click 'Run'
On Mac
Load CrossOver into your doc so that 'CrossOver' appears on the title bar at the top of your screen
Highlight 'Programs' to access the drop-down menu
Select 'Run Command...'
Select the bottle that Outlook 2007 is in
In the 'Command:' field type:
regedit
Then click 'Run'
Both
A windows-like registry editor will open
Browse to:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Options\Calendar
Create a new DWORD value of:
UseLegacyFB
Set the value to (double click on the entry):
1
Close the Registry Editor and open Outlook 2007.
