Microsoft Office Sharepoint Services 2007 (MOSS 2007) includes online presence information, so that if you are logged in to your IM account (via Windows Messenger) and your colleagues are also logged in (via Windows Messenger), you can see their status anywhere their name appears in your intranet or portal, and contact them in a variety of ways:
But what happens when you can't see the presence information for yourself or for a colleague whom you know has an IM account (via Windows Messenger) and is logged in?
Some say that you have to add the intranet site as a trusted site, and this may be a necessary step for success, but in my company's case it did not solve the problem. It turns out that the IM address must match the employee's login address EXACTLY - i.e., if login is jdoe, IM address must be [email protected], not [email protected] or [email protected] or [email protected] etc. Microsoft spells this out here.
In my company's case, only one of us has a login name that matches their IM address. Most of the staff members have IM accounts that are tied to a personal e-mail account, so they can maintain their contact base if they change workplaces. Some want to keep their IM accounts and their work accounts separate on purpose. I would bet that this situation is the same in many organizations, in which case, how useful will this highly-touted presence feature really be?
Note: you can, of course, create a second IM account that matches your current login, and switch to Windows Messenger if you weren't already using it, but unless you import all your contacts within the organization, you'll only see online presence information for yourself.
