EAS devices still sync after an account is disabled or a password is changed

Original KB number:   2612821

Symptoms

EAS devices continue to synchronize after their account has been disabled. Devices also connect using an old password, after the password has been changed.

Cause

When an EAS device is set to synchronize items as they arrive (Direct Push), any changes made to the user's account in Active Directory can require 8 to 24 hours before the device recognizes those changes.

When using Direct Push, devices maintain an open connection to the server. Any changes made after the connection is established will not take effect immediately.

Resolution 1 - Reset Internet Information Services (IIS)

  1. On the Client Access Server(s) that the device connects to, select Start, select Run, type CMD, and then press ENTER.
  2. Type iisreset and press ENTER.

This will restart IIS services. You can also use the Services.msc snap-in to manually restart the IIS Admin service.

Resolution 2 - Recycle the Application Pool used by ActiveSync

  1. Select Start, select Administrative Tools, select Internet Information Services (IIS) Manager.
  2. Expand the server name.
  3. Select Application Pools.
  4. Right-click the MSExchangeSyncAppPool and select Recycle.

Note

In Exchange 2003, EAS shares the same Application Pool with Outlook Web Access.

Resolution 3 - Configure the device to use a manual sync mode

Depending on the device type, modify the synchronization settings to use a manual sync and then wait a few minutes for the connection to be reset. On the next manual sync attempt, a new connection is established.

Resolution 4 - Shut down the device

Power off the device and wait a few moments, then turn it back on.
