I seem to have worked it out.
Got a couple of them up and running in Outlook no problem now.
Thanks for all the assistance fellas, cheers once again!!!.
One thing I noticed is that when you configure the mail client in the control panel, it gives you the manual settings to enter, but for some reason the
Mail Server Username has a "+" in it instead of "@", e.g. enquiries
+indagatio.co.uk.
Why is that?. Had to change the "+" to "@" within the Outlook settings to get it to work.
