Email Management Database

I have several email box in which i receive emails and I have approx 100 users accessing that outlook email box simultaneously. It is more like a ticket system.

I need a database to be created where all these outlooks emails come direfctly and all the users can pull emails and work on them.

The front end needs to be web based so .net is preferred while for backend please advice if we can use access mysql or are we good with access.

There will be 100 concurrent users
