Hello, 
I would like one of my colleagues to have access to archived projects without being an administrator. 
Is this possible?

Hello Eliott

I am afraid that the system administrator is the only user with this permission. You can give non-admin users permission to archive projects, but this will not allow them to see projects that have already been archived.

If this is an important feature for you, please consider creating a feature request for this topic. -> Feature Request
