Does anyone know how long a zoom link lasts. I have to set up appointments and it would be great to be able to send a generic zoom link that we can use for all patients and not have to set a new one for each patient.
For you situation, I would recommend scheduling a no-fixed-time meeting, which will last up to 365 days from the date you last used it. As soon as you use it again, that timer is reset back to 365 days. If you are going to use the same meeting for all your patients, I'd strongly recommend using waiting room as well, as that will allow you to control when each new participant can join the meeting and can prevent your next patient joining while you are in a session with someone else.
Hope that helps and please make sure to mark the solution as accepted if this information is what you needed.
