Can't send emails using Windows Live Mail (using new 10 software).  HELP!...Erwin

I just updated my Windows Live Mail program and the calendar feature has disappeared.  I can still access my calendar when I use the live mail website, but would prefer to see it in my live mail program window.  I have already tried repairing the Live Mail program. 

I have a Windows 7 operating system. 

Yesterday I tried to add another windows live mail account to my desk top.  It will not get past the synchronizing stage (still)  I did all the repairs as suggested.  Now my windows live mail contact list has reverted to a very very old list.  How can I get back my latest list???  And fix the new account issue too

I need to print an email in windows live mail, can seem to find any way to do it
I've been having problems on & off with email asking for password over and over. Now it is saying in the details that the "account is locked by another session". Please help. Going on 3 days without mail!

Windows Live Essentials Live Mail not working AGAIN! It asks for password over and over. I have checked every setting and changed password a number of times and nothing works. When I download another email program it won't load the emails saying that my email account is locked! I uninstalled Windows Live and reinstalled...nothing. Thanks for any help.

I down loaded Windows 10 and it did not recognise my internet connection, BT Help said it was a software problem so I uninstalled it. Now my windows live mail is corrupt. I can not delete any mail dating from the time W10 was installed. Has anyone got the answer? I am also fed up with the W10 and windows 11 explorer icons popping up every time I log in asking me to down load them and I can not remove them!

Any tips would be appreciated.   I have read the other posts but none refer to the new client.
