MC772556 - Microsoft Teams: Shorter meeting URLs

Updated February 28, 2025: We have updated the rollout timeline below. Thank you for your patience.

Please note that information about meeting link expiry changes related to this rollout has been added.

We are reducing the length of Microsoft Teams meeting URLs for easier sharing. This rollout applies to all Microsoft Teams platforms (Teams for iOS, Android, Mac, Teams devices, desktop, and web).

This message is associated with Microsoft 365 Roadmap ID 381953.

When this will happen:

Targeted Release: We will begin rolling out mid-February 2025 (previously mid-January) and expect to complete by late February 2025 (previously late January). Only Meet Now use cases (except Meet Now in chats and channels) will be affected in this timeframe. There will be no impact on the scheduled meetings in this phase.

General Availability (Worldwide, GCC): We will begin rolling out mid-May 2025 (previously mid-April) and expect to complete by late May 2025 (previously late April). Only Meet Now use cases (except Meet Now in chats and channels) will be affected in this timeframe. There will be no impact on the scheduled meetings in this phase. Rollout for scheduled meetings and channel Meet Now will be started in early July 2025 and expected to be completed by mid-July 2025.

General Availability (GCC High, DoD):  We will begin rolling out early August 2025 (previously early June) and expect to complete by mid-August 2025 (previously late June).

How this will affect your organization:

The new URL syntax is: https://teams.microsoft.com/meet/<meeting_id>?p=<HashedPasscode>

To make meeting URL shorter, we are removing several parameters such as tenant ID, conversation ID etc. This change serves two main goals: 1) improving usability of URL during sharing and 2) making the URL more secure and less susceptible to malicious attacks.

Here are some details about how meeting links work and when they expire:

1. In case the meeting organizer gets removed from the tenant, the links to the meetings scheduled by them automatically expire.
2.  Every meeting link expires in 60 days after the scheduled event or in 8 hours, if it was created as Meet Now. Learn more about expiration timelines for different types of meetings.

With the Short Meeting URL release, expiration limit will be applied to all newly created links.

Once the change to Short Meeting URL is released, all newly created meetings will expire as described in the documentation: 60 days after meeting ends for scheduled meetings and 8 hours after creation for Meet Now. Once this expiry period is over, in case someone clicks the link (e.g. outside of Teams app OR in the meeting details inside Teams calendar section), they will be unable to join the meeting.

Note: Old links created before short meeting URL release will continue working as it previously was (user will be able to join even after the documented expiry limits).

The reason why we are making this change is simple: security is our topmost priority. Maintaining a high security level is essential to protect sensitive data, prevent financial losses, ensure business continuity, and meet compliance and legal obligations. It is a critical aspect of modern digital life and business operations. This adjustment is designed to enhance the security of Teams meeting links, thereby better safeguarding the customer tenant. We want to be on par with modern security standards, that’s why the new behavior is a step in the right direction that we must take. It’s not possible to keep the current behavior. If you think it breaks some of your business processes, please leave comment to the MC post and describe your case there.

Recommendations in case the meeting link has expired:

For meeting organizer: We recommend scheduling a new meeting. If the meeting organizer got removed from the tenant someone else should reschedule their meetings from scratch.

For participant: Please reach out to the meeting organizer and ask them to reschedule the meeting or send you an updated link.

What you need to do to prepare:

You may want to check if you have any integrations that use parameters from URL. After the rollout, the URL will only contain the meeting ID. Parameters such as tenant ID, organizer ID, conversation ID and message ID will not be in the URL.

You may inform meeting organizers from your tenant who use expired meeting links, or you may want to make a tenant-wide announcement about this change.

This rollout will happen automatically by the specified date with no admin action required. You may want to notify your users about this change and update any relevant documentation as appropriate.
