(13. Nov, 20:55) Resolved - While Microsoft has not yet declared the incident as resolved, we can no longer observe any issues with our integrations. For further details about this outage and the root cause please follow the official Microsoft incident (MO1550821).

(13. Nov, 15:33) Disrupted - Microsoft has confirmed that the affected Microsoft 365 services are becoming available again step by step (Microsoft incident MO1550821). We can confirm this improvement on our side as well.

However, we are still seeing functional limitations in some of our products.

(13. Nov, 13:20) Disrupted - Following our initial notification, we have mostly completed our detailed analysis of the impact of the ongoing worldwide Microsoft 365 outage (Microsoft incident MO1550821). The cause remains in Microsoft’s infrastructure, and Microsoft is working on a resolution. Functions with no dependency on Microsoft 365 are not affected.

The following products are currently affected:

d.velop documents platform

• Displaying and editing M365 Office documents via the Microsoft M365 Office integration is, to the best of our knowledge, not affected. Due to the current information situation, we cannot fully rule out an impact.
• Saving emails from the Outlook integration to d.velop documents is currently not working.
• Shared mailboxes are currently not being processed by the d.velop content crawler. Processing will be caught up automatically once Microsoft has resolved the issue.
• Email notifications sent via the Notification app may be limited if M365 is configured as the email delivery option.

d.velop for Microsoft Teams

• Sign-in and embedding of content from d.velop documents in Teams continue to work.
• Sharing documents in Teams channels is currently not possible because Microsoft’s people search is unavailable.

d.velop documents for M365 and d.velop contracts for M365

• Both products use Microsoft’s index-based search, which is currently unavailable. The following functions are affected:
  • Search, sharing and input fields with people search
  • Some settings in the admin area
  • d.velop documents for M365: structures based on content types and search-based views
  • d.velop contracts for M365: some dashboard views
• Your stored documents and contracts remain unchanged. The functions will be available again as soon as Microsoft has resolved the issue.

d.velop connect for MS SharePoint

• The integration relies entirely on Microsoft’s search and is therefore currently unavailable. Documents from connected third-party systems cannot currently be stored in SharePoint.
• Once the disruption has ended, please check your storage jobs and restart any failed ones. This also applies to storage scenarios involving d.velop inbound.

d.velop invoices, d.velop invoices for SAP and d.velop invoices for M365

• d.velop invoices (T Cloud Public): Because Exchange Online is affected, the mailbox service of d.velop inbound currently cannot retrieve invoices from Microsoft 365 mailboxes. Invoices received by email in Outlook mailboxes are therefore not automatically imported into d.velop invoices.
• d.velop invoices (AWS) and d.velop invoices for SAP: Emails from Outlook mailboxes are currently not automatically forwarded to the d.velop cloud mailboxes. As a result, no workflows are started for new invoices in Outlook mailboxes.
• d.velop invoices for M365: Emails from Outlook mailboxes are currently not automatically forwarded to the d.velop cloud mailboxes. If you use the previous communication method (searching for new invoices in SharePoint), no new workflows are started for documents in SharePoint either.
• Once Microsoft has resolved the issue, invoices received in Outlook mailboxes during the disruption will be transmitted to d.velop and new workflows will be started. No action is required on your part.

We are monitoring the situation closely and will provide an update as soon as we no longer detect any disruption.

(13. Nov, 07:00) Disrupted - This morning, we detected a disruption caused by a major worldwide outage of Microsoft 365 services (Microsoft incident MO1550821). The cause lies in Microsoft’s infrastructure, and Microsoft is working on a resolution.

We are seeing a general impact on our cloud offerings, as several d.velop solutions rely on Microsoft 365 services such as Exchange Online, SharePoint Online, Microsoft Teams and Microsoft Graph. As a result, some functions may currently be unavailable or only partially available. Functions with no dependency on Microsoft 365 are not affected.

We are currently analyzing the impact in detail, product by product. We will publish a detailed update as soon as we have a clear picture of the affected functions.

We are monitoring the situation closely and will provide further updates as the situation develops.
