How many members can a team have? How many channels can you create? If you manage Teams or set up a large project, sooner or later you'll hit a limit. Here's an overview of the most important Microsoft Teams limits in plain language.
Microsoft adjusts these limits regularly, so always check the official limits page.
Teams and channels
| Item | Limit |
|---|---|
| Teams one user can create | 250 |
| Teams one user can be a member of | 1,000 |
| Members in one team | 25,000 |
| Owners per team | 100 |
| Org-wide teams per tenant | 5 |
| Private channels per team | 30 |
| Members in a private channel | 250 |
The number of channels per team is also capped, and deleted channels count towards it. Microsoft has raised this limit over the years; see the official page for the current number.
Chat and messages
- A group chat can have hundreds of participants. For large groups a team with channels usually works better.
- You can attach up to 10 files per message.
- Very long messages get truncated; share long text as a file or Loop component instead.
Meetings and events
- A regular Teams meeting supports up to 1,000 interactive attendees. Depending on your license, additional people can join view-only.
- For large events, use a webinar or a town hall. Town halls replace the retired Teams Live Events.
- Teams Premium gives you higher limits and extra features for webinars and town halls.
Teams (free)
The free version of Teams for personal use has stricter limits than Teams in Microsoft 365, including for group call duration and storage. The old Teams Free (classic) has been retired. More in use Microsoft Teams for free.
Tips for admins
- Check the number of teams and channels in the Teams admin center.
- Clean up inactive teams with an expiration policy so you stay well below the limits.
- Use PowerShell to manage large numbers of teams.
