How to alter column size in zimbra mail

To alter the column size in Zimbra Mail, you can follow these steps:

Method 1: Using the Zimbra Web Interface

  1. Log in to your Zimbra account using the web interface.
  2. Click on the gear icon () in the top right corner and select "Settings" from the dropdown menu.
  3. Scroll down to the "Display" section and click on the "Column settings" button.
  4. In the "Column settings" page, you can adjust the width of each column by dragging the border between the column headers to the desired width.
  5. Click "Save" to save your changes.

Method 2: Using the Zimbra CLI (Command-Line Interface)

  1. Open a terminal or command prompt and connect to your Zimbra server using the CLI.

  2. Run the following command to list all the columns in your mailbox:

    zmmailbox -z -m <username> -c "columns"

    Replace <username> with your actual Zimbra username.

  3. Identify the column you want to adjust and note its current width.

  4. Run the following command to adjust the width of the column:

    zmmailbox -z -m <username> -c "setcolumnwidth <column_name> <new_width>"

    Replace <column_name> with the name of the column you want to adjust, and <new_width> with the desired width.

For example, to increase the width of the "From" column to 200 pixels, you would run:

zmmailbox -z -m <username> -c "setcolumnwidth from 200"
  1. Run the following command to verify that the changes have taken effect:
    zmmailbox -z -m <username> -c "columns"

    This should display the updated column widths.

Method 3: Using the Zimbra Configuration File

  1. Edit the Zimbra configuration file zmconfigd.conf using a text editor.
  2. Locate the section that starts with [column_settings].
  3. Adjust the width parameter for the column you want to adjust. For example, to increase the width of the "From" column to 200 pixels, you would add the following line:
    from_width = 200
  4. Save the changes to the configuration file.
  5. Restart the Zimbra services to apply the changes:
    zmcontrol restart

    Note: Before making any changes to the Zimbra configuration file, make sure to backup the file and test the changes in a non-production environment.
