Microsoft’s Exchange Online service fell over in the early hours of this morning.The company’s status orifice initially figured that the problem mainly affected users in India as its engineers noted the wobbling at around 0700 BST. Just under an hour later Microsoft had to admit it was another global outage.It is the latest in what appears to be a battle of who can annoy their users more. Azure suffered a major outage earlier this week. Rival Apple then hit back with its own wobble before Microsoft continued the TITSUP* tit-for-tat this morning.The mystery issue afflicted apps using Exchange Online protocols, including Outlook on the desktop, mobile devices, and “those dependant on REST functionality,” Microsoft said. The company was taking a long hard look at what it might have changed in recent days that might have broken something.
Microsoft eventually pinned the blame on a “recent configuration update”, rolled it back and, at time of writing, was “monitoring the service” for signs of life.
Users reported problems sending and receiving mails, accessing folders and attachments, or even being able to log into their services. Some noted difficulty synchronising between Azure Active Directory and Exchange Online while there were also isolated reports of SharePoint and Teams struck by the curse of bork.
