Does anyone at the school use an Exchange Server? Does everyone? Just for mail? For mail and calendaring?
If Exchange is in use, are other server options available? Do you need to use Outlook or the Outlook web client, or are other clients such as Thunderbird fully supported?
How well is Exchange Server supported? Are there problems with it? Does it work just fine for you?
Please let me know what school you're at. Thanks for your help!
