Room mailbox unexpectedly disappears from an Outlook 2010 meeting invite

Symptoms

When you use Microsoft Outlook 2010 to organize a meeting and invite a Microsoft Exchange Server resource (room) mailbox to the meeting, all resource mailboxes that you added to the meeting unexpectedly disappear.

Note This problem only occurs when the Room Finder is visible.

Cause

This problem may occur for the following reasons:

  • The primary SMTP address of a resource mailbox that you add to the meeting contains an ampersand (&) character. For example, the SMTP address is R&DLab@contoso.com.
  • The added recipient has set his or her working hour range to span midnight (12:00 AM) in Outlook.

Resolution

Use one of the following methods to resolve this problem.

Method 1: Install a hotfix update

To resolve this problem, install the following hotfix package:

2687392 Description of the Outlook 2010 hotfix package (Outexum-x-none.msp): August 28, 2012 

Method 2: Hide the Room Finder

To hide the room finder, click the Room Finder in the Options section of the Ribbon on the meeting item.

Method 3: Remove the ampersand character from the primary SMTP address of the resource mailbox

Contact the administrator for your organization to have them remove the ampersand character from the primary SMTP address of the resource mailbox.

Method 4: Change the working hours of the recipient so that they don't span midnight in Outlook

To change your work days and times, follow these steps:

  1. In Outlook, click the File tab.
  2. Click Options, and then click Calendar.
  3. Under Work time, select the Start time and End time of your work day. These are used primarily for your free/busy availability times for meeting requests from other people.
