	(Updated) Teams meeting invite recipients limit from Outlook	Updated June 16, 2021; We have updated the message below to clarify this impacts Win32 and Win64 clients. Thank you for your patience. We're making some changes to limit the number of individual recipients allowed for scheduling a Teams meeting from Outlook (Win32 and Win64 client only at this time).

This limit does not apply to the content of Distribution Lists and therefore we encourage users to use Distribution Lists when inviting a large number of attendees to a Teams meeting.

MC276028	(Updated) Plus addressing to be enabled for all Exchange Online customers	Plus addressing support in Exchange Online was released in September 2020 as an opt-in feature.

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. [Key Points;] 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.
