Outlook rules stop running after mailbox reaches quota

Minimal guidance for messy support realities.

Scenario

Users report server-side rules stopped moving mail automatically after the mailbox approached or hit storage limits.

Recommended Resolution Path

  1. Confirm whether the mailbox was over quota and whether warning thresholds were recently cleared.
  2. Review rule size, complexity, and whether multiple clients are creating conflicting rules.
  3. Check archive behavior and large folder growth that may be driving the quota issue.
  4. Have the user validate rule operation from Outlook on the web after cleanup.

Technician Notes

Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
