Exchange system manager (ESM) is needed for this schedule. ESM is compatible only with 32 bit machines. Please move the product to a 32 bit machine on which ESM can be installed.

Cause:

Exchange System Manager is required for Mailbox Permission gathering in Exchange Server 2003 environments. However, 64 bit servers cannot accommodate Exchange System Manager (ESM).

Resolution:

To overcome this issue, uninstall the product and re-install it on a 32 bit machine where Exchange System Manager is available.
