What is Microsoft Teams "Error M" Memory Error?

The Error M in Microsoft Teams signals a memory-related failure, typically when the app exceeds available RAM or hits a leak.

Key symptoms:

  • Sudden app freeze or crash with "Error M" code.
  • High CPU/RAM usage in Task Manager.
  • Slow loading of chats or meetings.
  • Repeated restarts needed. ⭐

  3. Resource hogging: Multiple tabs, extensions, or background apps compete for RAM.
  4. Corrupted installation: Faulty updates or conflicts.
  5. System limits: Low RAM (under 8GB) or virtual memory issues.
