but I really need to help her out here first!
Do her a real favor and switch her to hosted Google apps?
That would certainly have been my choice. It would have been cheaper, too. This company is charging $25/month for unlimited storage for all users, or $15/month for something like 2GB total for all mailboxes. Google Apps would have been better for a three-person company (at $50/user/year), but honestly the calendar and contact syncing isn't quite there yet for Outlook, and I keep running into people who are obsessed with continuing to use Outlook.
When this Exchange stuff works correctly, it's fantastic. Between the three users in this company, there's an iPhone, Android device, and a Blackberry. The first two were a breeze to set up and took about two minutes before everything started syncing perfectly. The Blackberry, on the other hand, is a PITA. The user is going to have to upgrade her $30/month plan to a $45/month plan in order to be put on a BES instead of a BIS, and the configuration process is a bit more complicated. Plus, the user only has contacts in her phone, and doesn't want to sync it with Blackberry Desktop. So I don't know if setting her up for the BES will wipe out all her current contacts, sync them up to the Exchange server, or do nothing with them. I'll just back them up to my laptop first and go from there, but still, the Android and iOS processes were cake compared to the stupid Blackberry. I always forget how much I despise that interface...
