Windows Mail login problem

[willythecat]

Not much to go on system detail wise but someone l know uses Windows Mail and was logged into their account.
Then for some unknown reason (don't ask!) they had their whole computer system reloaded from scratch and now, when they try and login to Windows Mail, it says they can't because the account is already in use (by them!).
I know that if you forget your password you can get this changed, but how do you get back in if you are technically still logged in already?
Hope the above is general enough for someone to help.

This doesn't make much sense.  I believe many email providers will automatically log off after some length of inactivity.

Most likely, this person can access their email account via web browser.  If they've never done this, they may need to contact their ISP for instructions.  I'm assuming this a POP mail account, since they are using Windows Mail.  It is, isn't it?

By accessing, or attempting to access, their email account via web browser, they should be able to confirm they are using the correct password.  If they can't logon this due to password error, they will know they need to reset their password. They can use the common Forgot my password link.
