Have set up some new IMAP e-mail accounts in Windows Mail. They initially opened and downloaded content OK. But now ALL e-mail folders have "disappeared" from the Windows Mail screen - can't send or receive anything or see any previous e-mails or, indeed, anything other than one folder called "Folders" in bold followed by (25) - but nothing opens when I click on it.
If I go back into Tools/Accounts all the accounts are still there and all the setting seem fine.
What am I doing wrong?
