Microsoft 365 connector outage affects Claude services
Anthropic reported elevated errors and slow responses affecting its Microsoft 365 connector. Requests to mail, SharePoint, Teams chat and calendar could fail, and new connections might not complete. A later status update attributed the incident to a Microsoft 365 service issue and said mail, calendar and search tools were still failing for most requests. Claude for Outlook also remained affected, and no restoration time was announced in the supplied reports.
