SmarkWoW writes "The university I attend is currently looking to change the way in which is provides its students with an email service. In the past they used a legacy mail system which can no longer fit their needs. A committee has narrowed the possibilities down to three vendors: Google, Microsoft, and Yahoo. Representatives from these three vendors will be coming to our college and giving a presentation on the advantages of their systems. We're looking at other services these companies provide such as calendaring and integration with existing software that our university runs. What questions would Slashdot readers ask during these Q&A sessions? Which of these three companies would you recommend? Why? What advantages would each have that college-level students would take advantage of? What other aspects should we consider when making our decision?"
