How to Enable "Read and Manage" Permissions for a Mailbox in Microsoft 365

How to Enable "Read and Manage" Permissions for a Mailbox in Microsoft 365

Notes
  1. Permissions Scope: The "Read and Manage" permissions provide the user with access to read emails and manage the calendar but do not allow them to send emails on behalf of the mailbox owner unless granted additional permissions (e.g., "Send As" or "Send on Behalf").
  2. Limited Access: The delegated user accesses the mailbox as an additional account in their profile, not as the primary user’s login

Enable "Read and Manage" Permissions:

  1. Log into the Microsoft 365 Admin Center:

  2. Navigate to Active Users:

    • In the left-hand menu, select Users > Active users.

  3. Select the User's Account:

    • From the list of active users, click on the name of the user whose mailbox you want to configure permissions for (i.e., the mailbox owner).

  4. Open the User's Properties Pane:

    • Once the user's profile opens, click on the Mail tab.

  5. Configure "Read and Manage" Permissions:

    • Under Mail settings, locate and click Read and manage permissions.
    • In the "Read and Manage Permissions" section, click Add permissions.
    • In the search box, type the name or email address of the user(s) you want to allow to read the mailbox.
    • Select the user(s) from the list and click Add.

  6. Confirm the Permissions:

    • The selected users now have permission to read and manage emails and the calendar from the specified mailbox.
