We created a new email-to-case configuration and new organization-wide email address in a sandbox. The configuration was done by our Release Management user (which doesn't have the System Administrator profile). End users received their respective verification emails but were unable to complete the verification process. They clicked on the link in the email which opened up a browser window with the Verify Email Address button. After clicking on the Verify Email Address button, the browser screen appeared to be refreshing or reloading for several minutes and never displayed a confirmation message. We confirmed the verifications were still pending in setup. We worked with multiple users and retriggered the verifications multiple times (ensuring that links in the email were only clicked on once) but the only way we could get a successful verification was if the person retriggering the verification and clicking on the link in the email had the System Administrator profile. I submitted a Salesforce Support case to inquire if there was a process change. The resolution indicated that there might be an issue with a Summer '26 patch and timing of user verification of email addresses on their own user record in our sandboxes. We did some light experimentation in other sandboxes but still couldn't get the verifications completed without a System Administrator. Given the resolution we had been provided, it seemed that we shouldn't encounter the issue in production so we moved forward and created the email-to-case and organization-wide email address in production. Unfortunately, we had the same issue in production so someone with the System Administrator profile both retriggered the verification emails and clicked on the verification link in those emails.
Has anyone else encountered this behavior? TL;DR, someone with the System Administrator profile had to trigger the verification email AND click on the verification link in that email in order to successfully verify new email-to-case and organization-wide email addresses.
Hi folks. Here's the help topic on this , https://help.salesforce.com/s/articleView?id=005388172&type=1, the recommended resolution is to have the user who received the email forward it to the System Administrator who initiated the verification so that user can complete it.
