It should not. Not unless the amount of data to transfer will saturate
your connection for 2 minutes at least.

Which Squid version are you using?

Most likely there is a problem. As a first test try disabling
persistent connections in Squid.

   client_persistent_connections off
   server_persistent_connecctions off

I don't think this will make much of a difference (assuming the
connection between your Squid server and OWA is a good one), but this
can be done by reconfiguring the IIS server where OWA runs to send
the header "Cache-Control: public" on requests for static shared
objects such as the images. This will tell Squid that these objects
are public shared objects and can be cached.
