Exchange System Manager for Exchange Server 2003 running on the Windows Vista operating system.
SMTP current session node is not supported (SMTPadmin.dll cannot be registered).
NNTP property view is not supported (NNTPadmin.dll cannot be registered).
Installing Exchange System Manager on the same computer as Microsoft Office Outlook is not supported, because MAPI CDO cannot be installed.
You may encounter the following issues during uninstall:
If Exchange System Manager is open during the uninstall process, Microsoft Management Console (MMC) is likely to crash. To resolve this, manually close the Exchange System Manager.
If the MAPI CDO package was uninstalled manually before uninstalling the Exchange System Manager, a runtime error may appear. This error can be ignored and the uninstall process will complete successfully.
