I received a "Could not login to calendar server" error accessing Calendar in WebMail

This error is usually occurs for one of the following reasons:

  • The GroupWare service is not running
  • The port for the GroupWare service is not open
  • The GroupWare service is not enabled for the account trying to log in
  • The ODBC Connection for GroupWare is not set properly or the DB is not accessible
  • The DSN (Data Source Name) for GroupWare wasn't installed properly
  • The GroupWare engine is not enabled at all

The following guidelines should help you diagnose the problem:

The GroupWare service is not running

Go to System -> Services menu node in Merak Configuration Console and check if the GroupWare service is running there.

General Tab - List of Services

If the GroupWare service is stopped then press the start button to start it

The port for the GroupWare service is not open on your FireWall/Router

You can check the port that the GroupWare service is running on in System -> Services -> Select the GroupWare service and click the Properties button.

Verify that this port is open on your FireWall and/or Router.

GroupWare service is not enabled for appropriate account

Go to the GroupWare node -> General tab in Merak Configuration Console.

General Tab

The ODBC Connection for GroupWare is not set properly or the DB is not accessible

Go to GroupWare menu node and click the ODBC Settings button. The default connection is set to IceWarpCalendar DSN which is pointed to the calendar.mdb file in Merak\Calendar folder.

ODBC Settings - GroupWare

Click the Test Connection button to see if everything is ok. A successful test will display -

MS SQL 2k - New DSN 8

If the test is unsuccessful please continue to the next section

The DSN (Data Source Name) for GroupWare wasn't installed properly

This was probably caused at installation time, maybe by Merak not having full access rights to the DSN.

It is recommended that you re-install Merak ensuring that the full rights are granted to the DSN Merak will use..

If you wish to attempt to create the DSN without re-installing Merak please follow the instructions here.

GroupWare engine is not enabled at all

Go to GroupWare menu node and ensure that the Active checkbox is checked.

General Tab
