Microsoft<\/a> is making progress restoring Outlook after a widespread outage disrupted access to email and several other Microsoft 365 <\/a>services. The company says some affected servers have returned to service and are remaining stable, but recovery is still underway, meaning users could continue running into connection problems.<\/p>\n Digital Trends <\/p>\n The trouble began on Thursday, November 12, with Microsoft investigating reports of users struggling to access their Exchange Online mailboxes through multiple connection methods across the Americas. The company later confirmed that the problem could affect Microsoft 365 connectivity in any region. Microsoft\u2019s latest updates suggest that the situation is improving, but the service isn\u2019t quite out of the woods yet.<\/p>\n What caused the Microsoft Outlook outage? <\/p>\n Microsoft initially pointed to elevated loads across multiple regions as a likely reason behind the connectivity errors. However, its investigation revealed that this wasn\u2019t simply a case of too many people trying to access their inboxes at once. Instead, a number of servers had unexpectedly become unavailable, putting additional pressure on the remaining infrastructure.<\/p>\n We\u2019re testing a configuration change to address a problem that\u2019s causing servers to fail automated health checks and become unavailable.<\/p>\n
