I can't access my Outlook sent messages I have recently changed from a desktop PC with Windows XP, Outlook Express and dialup, to a laptop with Windows 7, MS Office 2010 and PlusNet broadband. I am gradually getting used to the differences, but there is a glitch with MS Outlook. Whenever I send an email I get a message saying that the Sent Items folder is unavailable. However, my emails are sent successfully, a Sent Items folder does exist, and all the emails I have sent appear in it. How do I resolve this? It sounds as though you are using an IMAP email account, where messages you have sent are stored on a remote server. You can set Outlook to store your sent messages on your PC by going to File > Account Settings, select your account then click the Change button and More Settings > Sent Items tab. Finally, change "Save Sent items in the following folder on the server" to Save Sent item in the Sent Items folder on this computer." In earlier versions of Outlook this option can be found by going to Tools > Account Settings > Change > Folders tab.
