Microsoft Forms - as event registration - can i mark as SOLD OUT once we reach maximum response we can accomodate ?

Microsoft Forms does not support automatically closing a form or individual options when a specific response count (capacity) is reached.

Available controls are:

• Limit who can respond (e.g., only people in the organization, specific people/groups).
• Limit to one response per person.

However, there is no built‑in setting to:

• Stop accepting responses after a certain number of submissions, or
• Mark specific masterclass choices as “sold out” automatically once their individual limits are reached.

To manage capacity after the form has been sent:

1. Monitor responses manually.
2. When a masterclass is full, either:
   • Edit the form to remove or rename that option (e.g., add “– FULL / SOLD OUT” to the choice text), or
   • Turn off “Accept responses” for the entire form once the overall event is full.

For more advanced capacity handling (per‑session limits, automatic close on threshold), a different tool such as a booking system or a Power Apps/SharePoint solution would be required; this is not available natively in Microsoft Forms.
