After the Summer '26 release, clicking a Salesforce Email-to-Case routing address verification link or an Organization-Wide Email Address verification link while logged in as a different admin than the one who created the address causes the verification to fail. This is Working As Designed (WAD): the verification link is intentionally session-bound to the admin who initiated it.
Symptoms include the following: clicking the verification link redirects to the Salesforce login page, Device Activation intercepts the flow after login, and the address remains unverified. The issue occurs only when a different admin clicks the link.
This behavior is a security design introduced in Summer '26, not a bug. The EmailChangeVerification service requires the same user session for both initiation (clicking "Send Verification" in Setup) and completion (clicking the verification link in the email). If a different user clicks the link, the token mismatch triggers Device Activation, which blocks the verification. This behavior affects Summer '26 and later.
This article explains why Salesforce Email-to-Case routing address and Organization-Wide Email Address verification fails when a different admin clicks the verification link, and how to complete verification.
Expected result: Verification completes. Actual result: Device Activation fires and verification fails.

Option 2 (A different admin needs to verify):
