There are many ways to get the name of your email system. Microsoft 365 or Office 365 needs the name of the source email server to migrate mailboxes from. Step 1: Find the full name of your current email server To add users, see Add users individually or in bulk. If you are using Office 365 operated by 21Vianet in China, see Add a domain to Microsoft 365. For instructions, see Add a domain to Microsoft 365. If you use an email domain in your IMAP email environment, and you also want to use the email domain in Microsoft 365 or Office 365, you need to add the domain to Microsoft 365 or Office 365 as an accepted domain before you create users in Microsoft 365 or Office 365. Each user must have a target Microsoft 365 or Office 365 mailbox for the IMAP migration. You need to create your users in Microsoft 365 or Office 365 before you migrate their IMAP mailboxes from the source email environment.
