Sometimes Outlook clients time out when connecting to their Exchange 2010 servers via the LoadMaster, or Outlook clients do not respond when a CAS server fails.
To fix these problems, follow the step below in the LoadMaster Web User Interface (WUI):
- In the main menu, select System Configuration > Miscellaneous Options > L7 Configuration.
- Select the Drop Connections on RS failure check box. This feature will cause all connections between the client and LoadMaster to be immediately dropped on Real Server failure.
- In the main menu, go to System Configuration > Miscellaneous Options > Network Options.
- Increase the Connection Timeout to 86400. This will increase the idle connection timeout to 1 day.
