Microsoft Reference : #32838228 (Re-Opened)
Issue Status : OPEN
Issue Description : Please be aware, we have received reports that there is a re-occurrence of the intermittent issue whereby users are unable to access their Shared Mailbox via OWA.
Business Impact : Affected users are intermittently unable to access Shared Mailboxes via OWA, however they can access via the Outlook client.
Current Update : 21/09/2022 09:00:00 AM – Microsoft have identified an additional problem with their domain controller servers which is impacting their ability to respond to Domain Name System (DNS) requests. Mitigative activities are being taken to remove the affected infrastructure from rotation and they are working to implement configuration changes to address this issue, which initial observations indicate are successful in alleviating impact. We will continue monitoring the service as these changes take effect.
Your patience is appreciated whilst we support Microsoft to a full resolution.
