======Calendars on eM Client======
If you have used CalDAV calendars on Mozilla Lightning/Sunbird, then the eM Client configuration is quite different, but simple.

To add a CalDAV account to eM Client

  - Go to **Tools** -> **Accounts**
  - Click **New Account...**
  - Open the **Calendar** section and click on **CalDAV**
  - Press **Next**
  - In the **Account Address URL** box, type the base URL of your VPOP3's Webmail, followed by **calendar/<username>/**. Note that the username is case sensitive and must be //exactly// as it is defined in VPOP3. So, for the calendars for the **Postmaster** user, enter something like **http://192.168.1.1:5108/calendar/Postmaster/**.
  - In the **User name** box, type the VPOP3 account user name
  - In the **Password** box, type the VPOP3 account password (case sensitive)
  - Press **Next**
  - In the **Account name** box type a name you use to refer to this calendar
  - Press **Next**
  - Press **Finish**
  - Press **OK**

The calendars should now appear in the left column of the **Calendar** section in eM Client. Note that if the user has several calendars (in VPOP3 Enterprise) then all the calendars will be shown.
