Impact to users: Small
There is a known recent address issue impacting some Outlook 2011 users. When creating a new message, some users noticed that their name was associated with others' email addresses in the "To" field. Additionally, when Outlook tried to autofill this field, others' email addresses were also associated with the email addresses of previous recipients.
