Hi, Icreated an address list to combine all the employees : (Include UserMailBox, Exclude ConferenceRoomMailBox, Exclude EquipementMailBox). We had to create a shared mailbox to access to a public calendar (we tried with Sharepoint Services but we didn't had the results expected - Outlook 2003 clients are not able to update the calendar directly, they have to go to the web interface..) So everything is ok now with this shared mailbox but it appears in my new list of employees. I would like to exclude the shared mailbox from the list. I guess that I have to do this with a powershell command: set-addresslist ..... but I don't know wich parameter to key... I would like to do something like Set-AddressList Employees ... -and type -ne 'Shared' but it doesn't work... We also try to key "Shared" in the CustomAttribute1 but again, I don't know how tu put the parameters in my command. Could you help me please? Thanks!!

set-mailbox"shared mailbox name" -HiddenFromAddressListsEnabled

I have this error: Set-Mailbox : Missing an argument for parameter 'HiddenFromAddressListsEnabled'. Specify a parameter of type 'System,Boolean' and try again Could you help me?

try adding a $true to the end of the string (the boolean) http://technet.microsoft.com/en-us/library/bb123981.aspx

It works but it is not what I need. If I do that, I won't be able to add the mailbox to my mail account.. (My Outlook is in french so I don't know the exact term in english..) Thanks for your help! I appreciate.
