Email Address
An email address identifies the account that messages should be delivered (e.g., bbadger@wisc.edu). An account can have multiple email addresses. Each account in Microsoft 365 has only one primary address, but an account can have multiple alternate addresses. An account will accept email for any email address on the account.
Email Domain
In email addresses, the domain is the part of an email address comes after the @ symbol. For example, for the email address of "bbadger@wisc.edu", the domain is "wisc.edu".
Microsoft 365 Account
The location in the Office 365 system where your email, calendar, task list, and address book are stored. Each Office 365 account has one primary address, but can have many alternate addresses.
Permissions
In Microsoft 365, permissions can enable an individual to access another individual's mail, calendars, and contacts. For example, if User A wanted the ability to modify events in User B's calendar, User B would need to assign read/write/modify permissions to User A.
