Many thanks to both - roncerr and Roderunner - for tryng to help me.
However I am sorry to say I was misunderstood. The title of my thread shows that the problem is with Windows Live Mail 2011, it has nothing to do with my
server and the accounts I might have with my server. Incidentally my primary
account is firstname.lastname@example.org
. I have never lose MY CONTACTS, they are not available to me JUST FOR SECONDS, and this is
the minor problem I wanted to solve. I do have a hotmail account with a different
list of contacts. For each email account I have, my list of contacts are differents
and I have not lost any of them. And it is only with WLM 2011 that this minor incident is occurring.
Have already tried to repair WLM 2011 through Windows Live Essentials in Programs and Features of my Control Panel. It did not solve this little problem
which is proving to be stubburn and not easy to solve. Thank you to both
for your good intentions to help me.
