Xobni for Outlook
If you are using a program such as Worldox, Time Matters or Amicus Attorney to manage your email, Xobni (that’s Inbox backwards)may not be for you. Otherwise, however, Xobni is definitely worth taking a look at.
Xobni indexes your emails providing lightning fast searches (OK, other programs do that as well). However, it also creates a “social network” of your email based on emails that have been sent or cc’d to multiple people. This can be quite useful.
Also, if you click on an email, it lists how many emails you have sent and received from that person, as well as their phone number if they are in your contact list or even if their phone number is listed in the signature block but they are not in your contact list.
Xobni will also set up threaded conversations - so if you have exchanged emails over a period of days and they are lost in the mass of your emails, Xobni will break them out for you.
You can also use Xobni to schedule appointments - it will even find free time for you.
All in all, if you use Outlook as a primary method of organizing your practice and workflow, Xobni is definitely worth taking a look at. While technically in beta, it seems pretty trouble free and in my testing did not interfere with other programs Outlook was linked with.
