Originally announced at Ignite 2019, Plus Addressing has been announced as being available to Exchange Online from September/October 2020.
What is Plus addressing
This allows the addition of a suffix to the local part of an email address. An end user will then setup a specific email address to use when subscribing to a service. This then allows the filtering of mails using Outlook rules, or if there is no longer the requirement to use the specific email address, then this can be disposed of, E.g. if the address becomes subject to too much spam or non required communications.
