Who is your provider?
What type of mail account is it? POP3, IMAP or HTTP?
If Gmail and POP3, special settings are required.
Gmail: Using POP on multiple clients or mobile devices
If you still have problems, logging may help. To enable logging in
Windows Live Mail select Tools, Options, Advanced, Maintenance,
Troubleshooting. Check the box to enable and click APPLY. Run the
Send/Receive/Synch, then click the box to uncheck and APPLY.
POP3 enables both POP3 and SMTP logging.
The logging information will be appended to WindowsLiveMail.log in the
same location as the WLM Store Folder (click the STORE FOLDER button
above Troubleshooting to see its location).
The WindowsLiveMail.log can grow to be very large. You may want to
rename (or delete) the current log file before starting logging in order
to get a more manageable file size. WLM will automatically create a new
log file when needed if one does not exist.
