Updated August 12, 2021: Based on initial feedback, there are several scenarios where organizations do not wish to have plus addressing enabled. For those organizations, a new setting will be added to disable it before the change takes place in 2022. Thank you for your feedback.
Plus addressing support in Exchange Online was released in September 2020 as an opt-in feature. This was due to preexisting usage of plus signs (+) for email addresses in the service. At the same time, we made plus addressing on by default for new customers.
With the successful introduction of the feature, we are now making plus addressing an always-on feature and removing the opt-in setting. Due to legacy mailboxes with email addresses containing plus signs (+), we are announcing a long notice period to allow customers to transition away from these mailboxes or addresses. This includes mailboxes on-premises.
Timing: Starting in January 2022, plus addressing will be turned on for all customers and the setting will be removed.
Action: Retire any email addresses that contain plus signs (+) for hosted and on-premises mailboxes to avoid email delivery disruptions.
