Other Outlook Add-ins

  • Lookout, a great utility for those of you who have amassed lots of pst files with hundreds or thousands of archived emails. It can index and search all pst files at once as opposed to the standard Outlook 2000 search, which can only do one pst file at a time. Microsoft has purchased the development of Lookout and no longer supports this utility since it has been superseded by Microsoft Windows Search.

  • Xobni, (inboX spelled backward) used to have attracted a sizable crowd of enthusiastic users to save time in finding email, conversations, contact info and attachments in Outlook, but the product has been discountinued after its developer joined Yahoo.
