The only advantages would be the messenger element (speed, slight improvement in ease of use, see when people are logged in etc) within a secure, internal network. To be honest, I've pretty much had to invent a line of argument here; I'd had vague thoughts on business application, and you swiftly backed me into a corner.
Those aren't necessarily advantages in a work environment, if you look at them. As is, e-mail is already
THE biggest time-sink and productivity-inhibiting communicative element in the daily routine of any office-based employee. Corporations are actually trying to limit the time people spend with e-mail, because it takes away so much time from their productive work-flow.
Now, take the immediacy ("speed") of instant messaging, and you end up with people wasting even more times with unproductive communication. I know of several corporations (one of which is one of Europe's largest petroleum companies) which have effectively
banned the in-house use of IMs between staff, because it was even more problematic than e-mail.
I suppose my question is more, with the rise of other means of communication and the fall of email elsewhere, whether it would either become business-only (or at least very much business-centric), or whether they would make the same kind of switch - that could be for support reasons, developments in technology etc.
I suppose there will of course be something to supplant e-mail someday. However, with current plans of several European governments to install e-mail as an electronic signed document, that development may actually be slightly stalled to some degree.
That aside, I rather think IMs and e-mail will continue to co-exist for quite a while yet, due to their inherently different character. IMs are more suited to immediate, short-text dialogic discourse, whereas e-mail lends it self better to the communication of larger amounts of text and or documents.
But, perhaps I'm just biased. Personally speaking, e-mail is something quite close to a formal letter, while instant messages are rather intimate, fast-paced small bits, closer to a phone call; I keep my instant messenger contact under even closer lock and key than my e-mail address (because of its intimate, private nature). I would never want to give one up in favour of the other.
