The listing is short, but it touches a long-running complaint about Teams webinars and registration-based events. Here is what is confirmed, what isn't, and what IT admins and event planners should watch for.
What the roadmap entry says
The roadmap item gives these details:
- Feature: Invite attendees to register
- Roadmap ID: 573250
- What it does: For a registration-required event, organizers can send email invites to selected people and groups, asking them to register
- Status: In development
- Release ring: General Availability
- Target date: November 2026
- Platform: Web
- Cloud instance: Worldwide (Standard Multi-Tenant)
The wording matters. The feature invites people to register. The entry does not say recipients are registered automatically, added straight to the attendee list, approved ahead of time, or guaranteed a place. Registration still looks like a separate step that the recipient has to complete.
The roadmap also leaves several things out:
- Desktop and mobile Teams clients (only the web is listed)
- GCC, GCC High, DoD, or other sovereign clouds
- Licensing requirements, including whether Teams Premium or attendee capacity packs are needed
- Admin policy controls
- Which group types can be invited
- Whether the feature covers Events app events, calendar-scheduled webinars, or both
Microsoft's roadmap notes that all information is subject to change. Treat November 2026 as a target, not a promise.
Section summary: Organizers will be able to email chosen people and groups to prompt them to register. The roadmap confirms web, Worldwide multi-tenant, and a November 2026 GA target. Nothing else about how it works is confirmed yet.
Why this matters: the registration-link workaround
Teams registration has worked a certain way for years, and that history explains why this feature is useful.
For calendar-scheduled webinars, attendees usually don't get a Teams invitation. A Washington State Department of Enterprise Services support article notes that generally, the only people who receive an invitation to a webinar are the presenters. The attendees are given a link to register for the event and can add it to their own calendars. The same guide says only the presenters will receive an invite from Teams. The organizer will need to add the registration link to websites, emails, chats, and Outlook calendar items.
Microsoft's own support documentation for the older "meeting with registration" flow told organizers to build excitement and gather an audience for your meeting by sharing the details and registration link with potential attendees. You may want to publicize the event through social media, websites, email, chats, and so on.
In practice, organizers copied the registration URL, pasted it into an Outlook message, and wrote the invitation themselves. This caught people out often enough that a 2021 Nero Blanco guide warned that once you turn on required registration, the "add required attendees" field changes to Add presenters. The same guide pointed out that there is nothing to stop attendees registering more than once! That was observed in 2021 and may not reflect how Teams behaves today, but it shows how loose the copy-the-link approach has been.
A built-in "invite to register" email could close that gap. Organizers could target specific people and groups from Teams instead of handling the outreach in a separate mail client.
How this fits the Teams Events app
The Teams Events app already has something close to this. Microsoft's guide to creating an event in the Events app says that under Who can attend, organizers can specify who will have access to the event, invite people and groups, and turn on registration if needed. It also says attendees won't receive invites nor be able to view the event until you publish it, and that when you publish an event, invites will be sent to attendees automatically. They'll be able to view the event details, register, and join the event.
So the Events app can already send invitations that lead to registration. Roadmap item 573250 is listed specifically for the web, and Microsoft hasn't said whether it extends this capability to Teams on the web, adds it to calendar-created webinars, changes how the invite emails work, or does something else. My reading, based on general industry knowledge and not a Microsoft statement, is that this most likely brings the "invite people to register" experience to a surface that lacks it today. Wait for Microsoft's message center post or updated documentation before planning around any specific version of that.
Registration controls that already exist
Microsoft already documents a set of registration controls. These are current capabilities, not confirmed parts of the new feature, but they show what an invited person will probably run into.
In the Teams Events app (according to Microsoft Support):
- Registration is switched on or off while you schedule the event. After you save the event, you can't change that setting.
- The registration form automatically asks for first name, last name, and email, and includes Microsoft consent fields. Organizers can add preset fields or custom questions.
- Organizers can require manual approval, set registration start and end times, and turn on a waitlist. People move off the waitlist first-come, first-served.
- Requests are reviewed under Events > Manage > (event) > People & emails > Attendees, where organizers can view forms and approve or decline individually or in bulk.
- Insights shows registration counts, page views, and cancellations, and can be downloaded.
For webinars created from the Teams calendar (according to Microsoft Support):
- Settings are under Registration > Configuration: event capacity, manual approval, waitlist, and a limited registration window.
- Manual approval, the waitlist, and registration windows are labeled "advanced registration features." They are available for events with up to 3,000 attendees. Larger events, up to 100,000, need attendee capacity packs.
- Organizations that had Teams Premium before April 1, 2026, keep access to these features for events up to 100,000 attendees until their license expires.
Do those licensing limits apply to the new invite feature? Microsoft hasn't said. Don't assume they do or don't.
Section summary: The invite feature will sit alongside an existing registration system with approvals, waitlists, and registration windows. How the new invites interact with those controls hasn't been documented.
What admins should know
Admins should be careful with one area of documentation. Microsoft Learn's article on meeting registration covers the older meetings-with-registration feature, which Microsoft says is no longer supported for new use. Previously scheduled meetings and those created through Graph API were supported only until December 31, 2024, and Microsoft now points organizations to Teams events.
That article documents the Meeting Registration setting in Teams meeting policies, the -AllowMeetingRegistration PowerShell parameter on Set-CsTeamsMeetingPolicy, and a "Who can register" choice between Everyone and People in my organization. It also says meeting registration isn't available in Microsoft 365 GCC High or DoD. All of that applies to the legacy meeting feature. None of it establishes the policy model, cloud availability, or controls for roadmap item 573250.
Before November, admins can do the following:
- Track roadmap ID 573250 and watch the Microsoft 365 message center for a rollout notice. That notice usually carries the details the roadmap leaves out.
- Review your Teams events policies so you know who in your tenant can create events and webinars before a new email channel arrives.
- Tell event organizers the feature is web-only for now, if it ships as listed. Expect "where's the button?" tickets from desktop users.
- Think about mail governance. Emails sent on an organizer's behalf to large distribution groups could raise questions about sender reputation and internal communications policy. That's general guidance, not a documented issue.
- Don't promise invitees a seat. Nothing in the roadmap says an invitation skips approval, capacity limits, or the waitlist.
Bottom line
This is a small feature, but it addresses a real annoyance. For years, Teams registration has meant copying a link and handling outreach in Outlook. Roadmap item 573250 suggests organizers will be able to email selected people and groups from Teams and ask them to register, starting on the web in Worldwide multi-tenant tenants, with GA targeted for November 2026.
Until Microsoft documents it fully, the open questions are the event types it covers, licensing, admin controls, sovereign cloud support, and desktop and mobile support.
