Issue Description: Users may be unable to access the new Microsoft Teams desktop client.

More info: While Microsoft are focused on remediation, users may still use the Microsoft Teams classic desktop client to retain access to service functionality. Additionally, clearing the cache or restarting the new Microsoft Teams desktop client will mitigate this issue.
