Custom fields in book screen
In Microsoft Bookings you can’t directly change the subject line of the Outlook invite, but you can add a custom field to the booking form so people must enter a subject or short description when they book. You’ll find this option by editing the service, scrolling down to the “custom fields” or “custom questions” section, and adding a required question like “Please describe the topic.” Their answer won’t replace the invite title, but it will show up in the booking details and in the appointment notes, so you’ll know what the meeting is about before it starts. If you really want it to update the subject line automatically, you’d need to use Power Automate, but for most people the custom field works well enough.

Thanks, MrCharlesJenkins. This helps, but I have no "custom fields" or "questions" sections, only "schedule customisation".
It sounds like you’re using the new version of Microsoft Bookings, which no longer includes the “custom fields” or “custom questions” section from the classic version. In this new interface, you’ll only see “schedule customization,” and unfortunately, you can’t add extra fields yet. As a workaround, you can turn on the “Require customer notes” option in your service settings, that way, people have to type something before booking, and you can ask them to include the subject or topic there. If you really need that information to appear in the Outlook event title, it would require a Power Automate flow to update it automatically.
