Guys i logged in to wlm 2011 with my local server and yes its possible.
You must only have a wlm 2009 local server and wlm 2011 installed
and then boom you can log in but WARNING! This method is sometimes not working, because of the not support jet. Also please be patient, and try again and again to log in try to change the ports in the firewall or an good idea: Install radmin vpn and message to one of your friend to make he a local server, and then you can connect to your friends local server using radmin vpn only you must edit the hosts file and install the certificate. TRY OUT!! BUT SADLY MESSAGES DOESNT WORKING JET IN wlm 2011.
PC REQUIREMENTS FOR WLM 2011:
Suggested os by me: Win 7 service pack 1 or normal win 7
Unsuggested os: Win 10 , i dont suggest to install wlm 2011 on win 10 jet, because i tried to log in, but alway it says error. You must have win 7, or use win 7 virtual machine to do it.
For me this method doesnt work anymore or i must try to logg in with some tricks
but you can try too. Download the messenger 2011 and you must have a wlm 2009 server
and you know why wlm 2011 can log in sometimes
ANSWER> Because the wlm 2009 has got msnp18 and wlm 2011 has got msnp21.
But wlm 2011 is reverse compatible with the msnp18 which is 97% supported now by escargot
but only 97% not 100%.
SUGGESTED OFFLINE INSTALLER BY ME ONLY WORKS ON WIN 7 WINDOWS 10 too.
WARNING! You must download a real offline installer or named Windows Live Essentials 2011 Full Installer or full offline installer. Do not download web installer version of essentials, because it says an error at the end, it says error couldnt install the programs, because of the Original essentials download server is now today missing and discontinued.
