The Exchange 2007 and associated Blackberry services have been affected by an outage on January 11th 2012, between 11:10 AM and 11:20 AM. During the outage, approximately half of the Exchange 2007 users experienced slow performance and the other half were unable to access their mailboxes. Once service was restored, email held in the queue began to be delivered. As a result, affected users may notice a delay in the timestamp of when the message was sent and when it was received. The Exchange administrators are currently investigating the root cause for this outage. If further problems with Exchange 2007 mail delivery are experienced after 11:20am Wednesday January 11, 2012, please report them immediately to the IT Service Centre at 604-822-2008.
