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're continuing to review affected contact details to determine if an additional fix would be effective in recovering the small amount of remaining impact. In parallel, we're reviewing additional diagnostic information to investigate why these contacts remain unrecovered and establish the additional mitigation steps needed to fully restore them. 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 had incorrectly separated some PBCs from their associated profiles when specific contact information wasn't explicitly stored, causing affected contacts to appear as blank.
