1. Assign a license: in the Microsoft 365 admin center, locate the user account associated with the shared mailbox and assign it an Exchange Online license.
2. Reset the password: set or reset a password so the user can log in directly.
3. Convert the mailbox:
   • Go to the Exchange admin center.
   • Navigate to Recipients > Mailboxes.
