Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi Amy,
Yes, you can invite people outside your organization to join a Teams meeting. There is no separate limit for external participants.
The maximum number of participants depends on the Microsoft 365 license used by the meeting organizer.
Microsoft 365 Business Basic, Standard, Premium, and Teams Essentials: Up to 300 participants.
Microsoft 365 Enterprise E3/E5: Up to 1,000 participants.
These limits include both internal and external participants.
Also, people outside your organization do not need a paid Teams license to attend. They can join using the meeting link, even through a web browser without installing Teams, provided your organization's meeting settings allow it.
Since you mentioned that you are a nonprofit, I suggest checking which Microsoft 365 license your organization currently uses.
If you are planning to replace Zoom, Teams should be able to handle your regular meetings as long as you stay within these limits.
