Here is an image of me trying to add a contact to the current mail
As you can see outlook 2013 just adds the ; separator but not the email address. When I add a display name I can add the recipient, but not before then.
Is there a setting to allow me to add that contact to the 'to' field just by email address?
I would prefer not having to export fix in excel and re-import.
EDIT
I tried to export and import, however these contacts does not export as if they do not exist.
