Outlook 2010 frequently adds single quotation marks around email addresses when I send emails. There does not seem to be any consistent pattern to when or why. The same contact can either have quotation marks or not; the quotation marks are sometimes there when sending an original email, sometimes they appear when replying or forwarding. None of these contacts has quotation marks in the "Display As" field. [I use first & last name only in "Display As".]
Should mention that I sync contacts and email with iCloud.
