If a user’s SIP proxy address and the user’s default e-mail address are
different, Outlook 2003 SP2 cannot show presence information. By adding the
following registry keys for Outlook 2003 SP2, you can help prevent a problem if
these addresses are different.
Click Start, click Run,
type regedit, and then press ENTER. Locate the following registry subkey:HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\PersonaMenu Click Edit, point to
New, and then click DWORD value. Type QueryServiceForStatus, and then click OK.

New, and then click DWORD value. Type
