Convert mail enabled security group to shared mailbox
A nice question!
Converting a mail-enabled security group to a shared mailbox is a bit of a process, but it's doable. Here's a step-by-step guide to help you achieve this:
Prerequisites:
- The security group must be mail-enabled, meaning it has a valid email address and is configured to receive emails.
- You have the necessary permissions to manage the security group and shared mailboxes in your organization.
Step 1: Remove the security group's email address
- Open the Exchange Management Console (EMC) or Exchange Admin Center (EAC).
- Navigate to the "Recipient Configuration" or "Mailboxes" section.
- Find the security group you want to convert and right-click on it.
- Select "Properties" and then click on the "Email Addresses" tab.
- Remove the email address associated with the security group.
Step 2: Create a new shared mailbox
- In the EMC or EAC, navigate to the "Mailboxes" section.
- Click on "New Mailbox" and select "Shared Mailbox" as the mailbox type.
- Fill in the required information, such as the mailbox name, display name, and email address.
- Set the "Mailbox type" to "Shared" and select the desired storage quota.
Step 3: Move the security group's membership to the new shared mailbox
- In the EMC or EAC, navigate to the "Groups" section.
- Find the security group you want to convert and right-click on it.
- Select "Properties" and then click on the "Members" tab.
- Select all the members of the security group and click "Remove".
- In the "Members" tab, click "Add" and select the new shared mailbox you created in Step 2.
- Add the members you removed in Step 4 back to the shared mailbox.
Step 4: Update the shared mailbox's permissions
- In the EMC or EAC, navigate to the "Mailboxes" section.
- Find the shared mailbox you created in Step 2 and right-click on it.
- Select "Properties" and then click on the "Permissions" tab.
- Update the permissions to reflect the desired access levels for the shared mailbox.
Step 5: Verify the conversion
- Send an email to the shared mailbox's email address to verify that it's working correctly.
- Check the shared mailbox's properties to ensure that the membership and permissions are correct.
That's it! You have successfully converted a mail-enabled security group to a shared mailbox.
