    Well after pulling my hair out looking at various forums and resolutions to this problem I can confirm that sfc/scannow fixed the issue for me! I have no idea what the tool is or what it did - I just typed sfc/scannow on the admin command line (note: not just the standard command line) and went to bed. I woke up to find a message saying some files were fixed and my Outlook 2013 Outbox empty - Cheers Miked

    I had upgraded to Windows 10 on my new Acer notebook (Model R3-131T) installed Office 365 when I came across the issue. Outlook 2013 refused to send any mail using the IMAP Gmail account. The test messages that Outlook sends when setting up the email account worked fine but anything I tried to send just got stuck in the Outbox resulting in an error message. Anyway I can now send email from my notebook to my heart's content!
