How to manage rental equipments through Exchange Online

Around april, we have started using room reservations through Outlook before we were using a old version of Meeting Room Manager and had it configured to be able to send notifications of equipment we needed to different group.

I already know I would be using equipment mailboxes but how would I manage them?

We have over 1000 microphones, 20 laptops.  Should I define 1 of each and activate "allow conflicts"?

How do you the equipment mailboxes in your organisations?

You help is greatly appreciated.

Thank you.
