Email support ticket processing has recovered, and our Helpdesk Ticketing System is now operational. We are closing this Exascale incident.
This closure relates to the impact on Exascale’s ticketing service and does not confirm that Microsoft’s wider Microsoft 365 incident is fully resolved.

Update
We are starting to see inbound emails being delivered to Exascale. This is an encouraging sign of recovery, although normal email ticket processing has not yet been confirmed.
In its 12:58 GMT update on Friday 13 November, Microsoft reported sustained improvements across much of Europe and continued recovery across affected regions. Microsoft is still stabilising its infrastructure and working to reduce delayed email queues and backlogs; intermittent access issues and delayed delivery may continue.
Our Helpdesk Ticketing System remains degraded while recovery continues. Please use https://manage.exascale.co.uk/portal/login to raise and follow up support tickets, or call 0330 010 0140 if you need help. Please avoid sending duplicate requests by email.
