Microsoft Teams: Town hall chat messages now support up to 500 characters

Microsoft Teams town hall chat messages will increase from 200 to 500 characters starting early June 2026. This applies to all attendees with chat enabled, is on by default, and requires specific licenses based on event size. No action is required, and existing policies remain unchanged.

[Introduction]

We are increasing the maximum message length in town hall chat to improve participant engagement and communication clarity. With this change, attendees can contribute more meaningful messages without needing to split them across multiple posts.

[When this will happen:]

• General Availability (Worldwide): Rollout will begin in early June 2026 and is expected to complete by mid-June 2026.

[How this affects your organization:]

Who is affected:

Admins and users organizing Microsoft Teams town halls:

• Teams events or town halls with fewer than 3,000 attendees require a Teams Enterprise standalone license, or Teams in an A3, A5, E1, E3, E5, or E7 license.
• Larger town halls or Teams events (over 3,000 attendees) require either a grandfathered Teams Premium license or a Teams Premium attendee pack to support chat functionality.

What will happen:

• The maximum character limit for town hall chat messages will increase from 200 to 500 characters.
• This applies to all attendees when chat is enabled in the town hall.
• The feature will be on by default and cannot be turned off where town hall chat is enabled.
• There are no changes to existing meeting or town hall chat policies or controls.
• Existing compliance, moderation, and retention policies continue to apply without modification.

[What you can do to prepare:]

• No action is required.
• Optional: Inform event organizers and moderators about the increased message length to help them prepare for richer audience interaction.
• Optional: Review internal guidance for town hall moderators if you provide instructions on chat usage or moderation.

[Compliance considerations:]

No compliance considerations identified, review as appropriate for your organization.
