Degraded EWS integration

We have identified a small set of customers affected by this issue. We have hardened our systems to handle the effect of unintentional misconfigurations, but load-based side effects can still occasionally affect other customers. We are monitoring the platform and will provide updates when additional actions are taken and/or the impact has subsided.

We are seeing unstable connections to the Exchange Web Services integration that powers our add-ins and other services dealing with Exchange meetings directly. Currently, it seems to only affect EU customers, but we are investigating the extent and impact as well as the root cause, and will keep you updated.
