How to appear offline in MOC

Sometimes it is nice to be able to appear offline when you are logged in using Office Communicator. Setting for using this is when you need to be offline but appreciate being able to see presence of others in Communicator, Outlook and Sharepoint. To apply this you need to use regedit:

  • You need to create following registry DWORD and set its value as 1 to enable it.
  • The DWORD name is EnableAppearOffline, type is REG_DWORD and location is
    • My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator.
  • After making above change, exit from office communicator (from system tray) and relaunch it.

Phones and Devices Optimized for Microsoft Office Communicator

Optimized for OCSAn important part of implementing Unified Communication in an organization is to use equipment that is supported by OCS. Products that are Optimized for Microsoft Office Communicator can be found over at technet using this link:

I have tested a lot of the Polycom products, including CX-5000 (Round Table), the Microsoft webcams and the Jabra  bluetooth headset. All these products works right out of the box when using Office Communicator, and my customers are really impressed by how simple it is to use these products.  To quote what one customer said: “I knew these products where easy to use, but when it worked right out of the box and without the need to restart the communicator client surprised me. This is something my users will adopt really quick.” 

Save password in MOC

If you have users with computers that are not joined to the same domain that their OCS account is homed to, the users always have to type the password when logging on using Communicator. This is the default setting in Communicator. There is a registry setting for enabling the “remember password” checkbox in the Communicator sign in dialog. I have tested it with non domain joined computers and it works like a charm. Here’s what you do

  1. Open Registry editor
  2. Locate the following key
    1. HKLM/Software/Policies/Microsoft/Communicator
  3. If the key is not there
    1. Create the Communicator folder
    2. Create the key as DWORD and give it the name SavePassword
  4. Set SavePassword=1.  
  5. This enables a checkbox to save password in MOC login dialogue.
  6. After the password is entered it is saved into the registry
  7. HKCU/Software/Microsoft/Communicator/AccountPassword
  8. This registry key store in hashed value. Changing the hash requires re-entering the password.
