Please ignore this message if your organization does not utilize Skyhigh Services for Microsoft Exchange Online. This update applies exclusively to customers managing Exchange Online environments through the Skyhigh Security dashboard.
At Skyhigh Security, we are committed to providing seamless integration with your Cloud Service Providers. To align with Microsoft’s upcoming retirement of Exchange Web Services (EWS) APIs in October 2026, we are migrating the Quarantine functionality of our Email DLP services to the newer Microsoft Graph API platform.
Because Microsoft manages Graph APIs as a distinct resource, this transition requires a one-time permission update. Please look out for upcoming updates containing instance-specific migration details.

End of Support Update: Legacy Data Identifiers features in CASB DLP - Important Update for Gov Cloud Customers
For CASB
June 30, 2026
We are writing to provide an important update to the End of Support dates for our legacy DLP Data Identifiers. We have extended the support timeline for our Gov Cloud customers until June 30, 2026.
This extended support timeline allows the completion of the transition of your tenant to an IAM-based login in Gov Cloud. This is a pre-requisite for the adoption of classifications which replace legacy DLP Data Identifiers.
Please reach out to your account representative or Skyhigh support to start with your IAM login transition.
Following the completion of IAM login transition, the migration away from legacy DLP Data Identifiers can begin. We encourage you to migrate in good time before the extended deadline to allow time for testing. Policies can be either migrated manually by your own teams, or Skyhigh can help by automatically cloning your existing policies to create copies using classifications.

Important Notice: End of Support for Logging Client – Action Required
For Logging Client
Skyhigh Security will officially end support for the Logging Client on June 30, 2026. The Logging Client, which currently collects SSE (Security Service Edge) web logs for analytics and investigations, will no longer receive feature updates or technical support after this date. However there would be no impact to the existing functionality.
Until March 31, 2026 – The Logging Client will continue to receive technical support. From April 1, 2026 to June 30, 2026 – Only critical security patches (CVE-related or high-severity vulnerabilities) will be provided.
After June 30, 2026 – No feature updates, regular fixes, or technical support will be available.
To ensure a seamless, secure, and scalable log ingestion experience, customers are advised to transition to its like-for-like replacement, the Log Collector, which provides equivalent functionality within the latest Skyhigh Cloud Connector. Alternatively, customers seeking a more modern, scalable, and streaming-ready architecture may choose to upgrade directly to Log Stream. Both Log Collector and log Stream are available under SIEM Integration (Inline) starting with Cloud Connector version 6.7.1 and above. These solutions offer unified log ingestion from SWG, RBI, Private Access, and Cloud Firewall, support multiple output formats (CSV, JSON, KVP) and transmission methods (Syslog, local storage, or direct streaming to SIEM/SOAR platforms), and align with ongoing SSE platform enhancements.
Action Required: Please initiate migration to the Log Collector or Log Stream at the earliest to ensure continued access to updates and future compatibility. Refer to the following resources to assist with migration and download:
- Migrate Logging Client to Log Collector – Documentation
- Log Stream - Documentation
- Download the latest Cloud Connector – Documentation
- Old Logging Client - Documentation
After June 30, 2026, Skyhigh Security will not provide feature updates or technical support for the Logging Client beyond security vulnerability patches.
