Note that we are not only an alternative, but also you may use 01.com Zimbra hosting with Google Apps.
In addition to our delivering support to all of your team members with mailboxes, not only a few of your technical people, some common reasons organizations choose Zimbra over Google Apps include:
- Free/busy time scheduling instead of calendar overlays
- Microsoft Outlook 2003/2007 sync (mail, calendars, contacts, tasks, photos, identities)
- Native Mac mail, ical and addressbook sync (mail, calendars, contacts, photos!)
- Thunderbird Mac/Win/Linux mail, contacts, calendar sync
- Mobile device off-line, over-the-air (OTA) sync, including iZimbra for iPhones
- Firefox extension to drag and drop files into briefcases for file sharing
