adding company email for another user

If multiple people need access to the same company email, use one of these Microsoft 365 options depending on the goal:

1. Give another user access to an existing mailbox
   • In the Microsoft 365 admin center, go to Users > Active users.
   • Select the user whose mailbox needs to be shared.
   • Open the Mail tab.
   • Choose the permission needed:
     • Read and manage permissions to let someone open and manage the mailbox.
     • Send as permissions to let someone send as that mailbox.
     • Send on behalf of permissions to let someone send on behalf of that mailbox.
   • Select Add permissions, choose the user, then select Add.
2. If the address is meant for a group, such as info@ or sales@
   • Create a shared mailbox instead of using one person’s mailbox.
   • This is the recommended option when multiple people need to manage email sent to one address.
3. If the same user just needs another email address
   • Add an alias to that user.
   • In the admin center, go to Users > Active users, select the user, then under Aliases choose Manage username and email.
   • Add the alias and save changes.
   • Mail sent to both addresses goes to the same inbox.

Important details:

• Managing aliases requires an Exchange-based admin role such as Exchange Administrator.
• If Manage username and email is missing, the user likely does not have a license assigned.
• Mailbox permission changes can take up to 60 minutes to apply.
• Alias changes can take up to 24 hours to update.
• Mailbox permissions only work within the same organization.
• If HiddenFromAddressListsEnabled is set to True, Send As and Send on Behalf do not work in Outlook Desktop because the mailbox must be visible in the Global Address List.
