Hello. This topic is old, but this is another vote for alternative installation location. I will try the suggestion by @bulljustin to see if it works.
In my case, business types are using Postman on a jump box in AWS. The machine is built from a system image (AMI) on demand. The jump box cannot have an internet connection so the sharing by teams will not work. Having Postman on a shared drive will give the various users access to the same data (assuming the sharing will work) and eliminate the need to update the AMI each time Postman has an update or new requests have to be added.
