Policy-based Encryption E and Advanced Portal URLs will be changing to reflect the symantec.com domain name.
Policy-Based Encryption (PBE) service encrypts your organization's outbound emails that match predefined conditions in your Data Protection policies. The external recipients are sent an email pick-up notification with a URL so they can retrieve the encrypted message from a secure web portal.
The email encryption pick-up portal URLs are going to change to reflect the symantec.com domain name.
The change will happen in 2 phases:
The transition would be seamless, the old portal URLs would be available and online for 30 days from the time of the change. This ensures that a message link (valid for 30 days) will continue to work after August 10th and August 31st respectively.
To prevent a complex set of policy rules from accidentally blocking access to essential websites, you can create a rule that specifically permits access to the following sites within your organization's proxy servers.
