Microsoft outage affects CatMail, April 5-6, 2010
Between 4:00 pm April 5 and 2:00 pm April 6, Microsoft had problems with their Outlook Live service that may have prevented some undergraduate students from sending or receiving e-mail via CatMail.
OIT will resend any official mass mailings that were interrupted by the outage. Individuals who received “bounce” notifications while trying to e-mail undergraduate students may need to resend those messages.
