You can create a shared mailbox in Microsoft 365 by navigating to Teams & Groups → Shared mailboxes, entering the mailbox details, and assigning members. If the shared mailbox tab is missing, verify tenant selection and permissions, or use the Exchange Admin Center to create it manually. https://inventivehq.com/knowledge-base/office365/creating-and-managing-shared-mailboxes-in-office-365/ https://youtu.be/31zeUF2OSCs https://www.lebow.drexel.edu/about/support-services/knowledge-base/managing-access-office-365-shared-mailbox https://www.godaddy.com/en-in/help/create-a-shared-mailbox-20302 Thanks Nimsara
