SYMPTOMS

After you change the password to your user account, you may still be able to log on to the Personalization page and Outlook Mobile Access for Exchange Server 5.5 using the old password. However, if you wait a period of time (30 minutes to hour), you are unable to use the old password. During this time, after the password is changed, you can log on using both the new password and the old password.

CAUSE

This issue can occur because the password and other parts of your user object are cached by Internet Information Server (IIS) for up to 15 minutes by default. These items are cached for performance reasons.

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, adjust this timeout value:
  1. Start Registry Editor (Regedt32.exe) on the IIS server that the user accesses OWA on.
  2. Locate the following key in the registry:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\InetInfo\Parameters

  3. On the Edit menu, click Add Value, and then add the following registry value:

    Value Name: UserTokenTTL (This value is case sensitive.)
    Data Type: REG_DWORD
    Value Range: 0 - 0x7FFFFFFF (This unit is in seconds.)

  4. Quit Registry Editor. You do not have to restart the computer or any services for the change to be applied.

WORKAROUND

To work around this issue, restart the World Wide Web Publishing service to temporarily clear the credentials cache.

STATUS

This behavior is by design.
