Microsoft Support and Recovery Assistant is a diagnostic and repair tool for Office and Teams issues; it does not specifically target or clear local profile caches.

The self-help diagnostics tool helps identify configuration or policy problems but does not flush the local client cache that holds profile data.

The new Teams desktop client stores profile information such as display names and profile pictures in a local cache to improve performance. After an administrator updates a user's display name or photo in Microsoft 365, the change is replicated in the cloud but the local cache on the user's device retains the old data until it expires or is cleared. Clearing the Teams client cache forces an immediate refresh, causing the updated name and photo to appear without waiting for the cache TTL.

The new Teams desktop client stores its own application cache separately from the web browser cache, so clearing the browser cache has no effect on the Teams client's cached profile information.
