Hi, I’ve been working on an MSN server over the last half a year or so (on and off, when I’ve had the motivation to tinker), and I just discovered you’ve beaten me to it! Although I’m slightly disappointed that I didn’t get there first, I’m very glad somebody else has done it - I wanted to see MSN live on, and luckily so did you guys, so that’s great.
Anyway, Escargot seems to be tidier and further along than my own efforts, so I don’t have a whole lot to offer, but what I do have is a nice healthy collection of MSN clients I’ve been gathering and testing, and I thought you guys might like them. I’ve just uploaded them to Archive.org, you can find them here: MSN Messenger Collection.
There are 118 builds, some of which are 9x/XP versions of MSN Messenger/Windows Messenger 4.x.x. I’ve also included protocol version and CVR ident information. Hope you find them useful, took me a bit of digging to find them, and it’s definitely not a full collection - many seem lost to time, particularly early (1.x) versions and those which were betas/leaks and got quickly superceded by fixed versions, but I think I got a nice spread across the years. I’ve also documented them (well, loosely speaking, it’s very vague and not particularly detailed) here (MSN Messenger History), where I’ve put the same version/protocol version/ident info plus some screenshots for any version I was able to make functional with my server.
Once again, good job on keeping MSN alive, great to see someone else still cares to preserve it.
Edit: Whoops, you can’t see the protocol/CVR info from that Archive.org link, just the files, this one has the description with that info in: Here.
Edit 2: Now uploaded the collection of Windows clients provided by @tristanleboss which can be found here: MSN Messenger Collection 2.
Added new wiki page with both collections and version info here: https://gitlab.com/valtron/msn-server/wikis/MSN-Messenger-Client-Downloads
