=== Resolution @ 2pm ===
We made some configuration changes to the Exchange environment and have monitored it for the last 3 hours with no performance issues.
If you see any, please contact support.
=== Start @ 10:00am ===
We have had reports the last 36+ hours of degraded or intermittent connectivity issues with our Exchange email environment. We thought it was corrected yesterday but it has come back up again today.
We have a Platform Admin dedicated to work on the issue until resolved today.
We will provide updates as they are available.
