It finally looks like there is a solution for a web-based exchange. In walks SCALIX. Now, how suite is that? Here is a full Linux based email system. The restrictions and costs of client licenses are diminished as another chip is shattered away from the rock.
This product has a lot left to be desired as a FULL service corporate email
option. First it is very flaky at best. You will need to shut down your
browser and start it up several times a day. Next - the search
functionality is very limited. You can only search for subject line
information or from and to. You cannot search email content.
Interesting, I knew it was had some issues, but we employed it and it was
pretty successful to date.
