I agree with the above, a meeting URL will never stop working. The expiry only relates to any PSTN dial-in numbers, CVI coordinates, and/or underlying meeting policies and
settings. According to the Microsoft documentation, the link will remain active for 60 days and that timer is reset every time the meeting is joined.
Because it looks like a long time I'd ideally like them to die quickly (next day) Needs to be minimum effort for the staff.
To get this feature more quickly, I have found a feedback in Teams UserVoice and you could vote for it.
Microsoft will always focus on customer’s feedback and experience, some new features would be added to the services based on customers' feedback in the future, and your
good ideas will be very helpful for them to improve the service. Your time, understanding and cooperation will be highly appreciated.
