Thanks for all your replies. I tried logging into Webmail to see if I could access my email account but unfortunately, it wouldn't let me in. However, I tried again this morning and it let me in. In my mailbox, there was one copy of the email I kept recieving and a long list of emails I have been waiting for that had failed to come through. I deleted the duplicated email and all the emails that were queued up came straight through in Outlook. Sounds like you were spot on Paul. Thanks again
