For very small businesses that need calendar sharing, MSN/Hotmail is one option, and MOOL makes it much easier to use. One common scenario that MOOL will work great for is when the Secretary needs to see the Boss's calendar, but they don't have an Exchange server. He subscribes to MOOL and sets up his Hotmail account so the message store is used as his default. This allows him to simply add new appointments and they're synced with the Hotmail calendar server.

The Secretary already has Outlook installed, and installs just the connector. She leaves her current PST as the default, and the Boss's Hotmail account has its own message store. Now, she'll always have a copy of his calendar (along with his mail and anything else in his PST, unfortunately.)

If you take advantage of this offer to upgrade to Outlook 2003, remember that the "Office envelope" features, including many of the email options on the File->Send To menus in other Office applications, will only work when you use the same versions of Outlook and Office applications. This effectively eliminates your ability to use Word as your email editor or do mail merges.

Normally $60, MOOL is priced at $45 for an introductory period.
