In Microsoft 365, an alternate address is any email address associated with a NetID@wisc.edu or service account (something@domain.wisc.edu). Any NetID or Service account may have any number of email addresses associated with it. These email addresses includes, but is not limited to, previous alias/alternates accounts and/or user/role/service accounts that have been consolidated with the NetID. A message destined to any of the alternate addresses will be delivered to the main address on the account (NetID@wisc.edu or something_domain@wisc.edu).
