Here are steps to modify a user’s rights:
1. Log in to Zimbra Administration Console using your existing credentials.
1. Then click on “Manage” on the left-hand side of the screen.
1. Select the specific account (user) that you want to modify.
1. Right click on the selected account and click on “Edit”.
1. After that, click on “Account Rights” to view or modify the user’s rights.
1. In this section, you can change different settings depending on what you want to modify. You can grant or revoke admin rights, modify viewing rights, change sharing settings, etc.
1. Once you’ve made the necessary changes, click “Finish” or “Save” to apply the changes.
Remember you would need administrative access to do this. Always be careful when changing user rights; granting too many rights may pose a security risk.
The exact steps might vary slightly based on version of Zimbra.
