First Login and The Mailbox Caching Setting
OWA caches the email address of every person an email is sent to, which expedites the address lookup process. However, when staff are converted to OWA and other OWA
users attempt to send email to their old @sps.lane.edu account, a bounceback with a non-delivery report (NDR) will occur. To avoid this system behavior, the mailbox cache
setting must be disabled. Once the entire organization is on the new system, this setting can be changed back. Additional information regarding this setting can be found here.
