ISSUE:
======
Exchange 2007\Rooms missing from "All Rooms" address list after Move Mailbox


CAUSE:
======
-In the RTM build of E2k7 there is a known issue that can occur after mailboxes
designated as "Room Mailboxes" are moved between mailbox stores.
-The attribute that identifies the mailbox as a "Room Mailboxes" is changed to the
attribute that represents a "User Mailbox"
-The value for the msExchRecipientDisplayType attribute for an account with a "Room
Mailbox" should be 7
-If this issue occurs after a move mailbox the value for the
msExchRecipientDisplayType attribute is changed to 1073741824 (this is the value
that represents a "User Mailbox".

WORKAROUND:
============
-You can verify this issue by using ADSIEdit.msc to view the
msExchRecipientDisplayType attribute for an account with a "Room Mailbox"
-The value should be integer value 7. If you have this issue the value will be
1073741824
-You can correct this issue by using ADSIEdit to change the value for
msExchRecipientDisplayType to 7.
-You can also modify this value in bulk by using ADMODIFY.NET, or using a script.
-After modifying the attribute you may want to speed up the process of making the
rooms visible in the All Rooms Address List by right clicking on it in EMC and
selecting apply. After this, forcing AD Replication may help as well.
-This issue is resolved in SP1 for Exchange 2007.
