Hi gmayor, your first suggestion is what did the trick with just one substitute of semi-colons in place of commas so that Outlook would recognize the string of addresses:

strTo = ActiveCell.Offset(0, -29).value & "; " & ActiveCell.Offset(0, -28).value & "; " & ActiveCell.Offset(0, -27).value
strCc = ""
strBcc = ""

Thank you very much gmayor for your help! I really appreciate it
