Microsoft is experiencing a global outage affecting email and other Microsoft 365 services. As a result, you may experience delays in email communications with Main Line Health.
Our hospitals and care locations remain open, and patient care continues safely and without interruption.
If you need to reach your care team or a Main Line Health location, please call rather than email. For general assistance, call 1.866.CALL.MLH (1.866.225.5654).
Please plan to attend your scheduled appointments unless you are contacted directly with different instructions.
We appreciate your patience as Microsoft works to resolve the issue.
