set-mailbox cmdlet

[SilverICE]

I know that I can convert a Mailbox User to a Room Mailbox by running:
set-mailbox <name of mailbox> -type Room

I've got about a hundred to convert. How can I convert the whole lot at once?

For mailboxes in an OU:
get-mailbox -organizationalUnit "ou=yourou,dc=yourdomain,dc=com" |
set-mailbox -type Room

For mailboxes with a common attribute value:
get-mailbox | where {$_.something -eq "specificvalue"}| set-mailbox -type
Room

The first query will be fast because it only search one location. The
second query will be much slower, because it search all users in the forest
and check each of them.

Very cool. Can you tell me how to add "Resource custom properties to a
Conference Room Mailbox? Will this allow me to display in the GAL if a
particular room has a projector, computer, etc? How does that info get in
there?
