Users may be unable to view contacts and Speed Dial entries in Microsoft Teams, Outlook desktop and mobile

Title: Users may be unable to view contacts and Speed Dial entries in Microsoft Teams, Outlook desktop and mobile User impact: Users may be unable to view contacts and Speed Dial entries in Microsoft Teams, Outlook desktop and mobile. More info: Affected users may observe missing contacts, blank or grey placeholder entries, or Speed Dial entries that can't be re-added. This behavior may occur across Microsoft Teams desktop and web experiences, Outlook Mobile, and Outlook desktop. More specifically, this issue impacts in-tenant contacts created in Microsoft Teams using the Notify when available presence notification option. Some older contacts may also be impacted under specific circumstances. Current status: We’ve completed deployment of our previous fix and determined that it only remediated impact for a small percentage of affected contacts. We’re validating an additional fix to address the remaining impact and, if successful, will begin deploying it to the affected environment. We anticipate to share a completion timeline by our next scheduled update. Scope of impact: Some users attempting to view contacts and Speed Dial entries in Microsoft Teams, Outlook desktop and mobile may be impacted. This information may be updated as our investigation continues. Start time: Friday, September 25, 2026, at 7:30 AM UTC Root cause: A problem with a contact-processing component has incorrectly separated some PBCs from their associated profiles when specific contact information isn't explicitly stored, causing affected contacts to appear as blank.
