Identified
Users of shared accounts may not be able to send messages or create calendar appointments when the accounts are accessed via the “Open Another Mailbox…” option within OWA. Sending messages in these cases appears to hang, though refreshing the browser window will reveal that the messages were sent successfully. Also, sending calendar invitations results in an error “The event couldn’t be created…” and the browser window will hang requiring the active browser tab to be closed.
OIT staff are aware of the problem and have reported it to the vendor (Microsoft). If you have questions about this issue or would like to report additional service impacts please contact the OIT Service Desk: https://oit.duke.edu/help
