Outlook.com Password Issue

I've always viewed by hotmail via Outlook but now there's something wrong with the account.  It will not retain or accept my password (even though I check the save box).  I've tested my password several times in the regular web view of Hotmail/Outlook.com and it's correct.  I've also tried deleting the hotmail file from Outlook and re-loaded it, thinking that an old password is somehow being stored somewhere.  Is there a registry setting somewhere that I can reset?

Is there a tech support that I can call?  Any suggestions would be appreciated.    thanks
