I need to change the time out for seesion to expire in OWA Exchange 2003.  i don't know what the default is, but I'm getting calls from branch offices stating the following keeps happerning: Your session has expired. To continue your work, please re-enter your domain\alias or your e-mail address and password, and then click Log On

Does anyone know a answer to this?

    "Note:  You can change the default timeout by changing the following registry setting:

    Registry Value: PublicClientTimeout
    Value Type: REG_DWORD
    Value Data: (possible setting decimal)


    Registry Value: TrustedClientTimeout
    Value Type: REG_DWORD
    Value Data: (possible setting decimal)

    On both registry values the possible settings will vary from 1 – 4320 (minutes). After changing these settings you have to restart your W3SVC service."

    Please not that the registry key on my server is slightly different from the one posted (perhaps a different level service pack?).

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ExchangeWeb\OWA on my system it is:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\OWA <-- Note the MS in front of ExchangeWeb.

    Just a quick note to help others.
