Email Services

As we migrate County departments to Microsoft 365 cloud hosted services, access to web email will change. There are two different links available below depending on whether your department has been migrated or not. Please Note: Once your department has been migrated to M365 use of a browser for email access will require Multi Factor Authentication (MFA).

This system is for the exclusive use of Sonoma County Government Employees and staff of other agencies within County Government Only. Any unauthorized access through this system will be prosecuted under applicable laws.

This is for authorized employee's usage for access to their e-mail accounts. Please note that in order to use this service you must have an email account with an established password.

If you have any questions regarding authorized access to this service, please contact your supervisor.

For system status and other technical questions, please contact the ISD-ServiceDesk or call (707) 565-2030.
