Office 365 Outage is Blocking Access to Mailboxes

The benefits of the cloud are well documented; you have increased flexibility to expand and contract services, the ability to quickly geo-replicate your data, and you always have the latest version of software available to you. But, when an outage occurs, ‘fixing’ the problem is beyond your control and you are left twiddling your thumbs.

If you are in Europe and you can’t access your Exchange Online services, you are not alone. Microsoft is stating that they are investigating an issue that is currently preventing its users from accessing Exchange, primarily that users are unable to access their mailboxes.

Microsoft believes that the issue is related to a networking configuration and they are currently looking into the issue. At this time, there is not a known timeline for restoration.

While Microsoft has posted on their Twitter account that they are aware of the issue and they have alerted admins in their portals about the impact. Further, if you look at Down Detector, it’s quite clear where the issue is impacting users.

These types of outages happen on occasion with Microsoft’s cloud services. And while this is not a global outage, it is certainly causing quite a few headaches for customers in Europe.

  1. <p>To be clear, the outage is only partially affecting the Office 365 EMEA datacenter region. It seems like most of those affected are in some specific countries (like Germany, Austria, Norway, and some Eastern European countries). I did hear one report of the outage affecting a UK tenant, but probably not in the UK datacenter region. I have been able to work all morning without any interruption (in Ireland).</p>

    • <blockquote><em><a href="#16064">In reply to Tony-Redmond:</a></em></blockquote><p>Problem is identified as being due to Azure Active Directory domain controllers. Tenants are spread across different forests in Office 365, so it looks like one or more forests are down.</p>
