Mailprotector experienced a Microsoft 365 tenant issue that prevented their support team from receiving email replies to their support address for 25 hours. The service temporarily switched to using zendesk.com email addresses instead of their standard mailprotector.com domain to restore email reply functionality. The issue was fully resolved with support emails returning to normal behavior from the mailprotector.com domain.

Support tickets and replies from Mailprotector will temporarily originate from a zendesk.com email address rather than our standard mailprotector.com domain. This is an intentional change we made to restore email reply functionality to our ticketing system.
Emails arriving from zendesk.com on behalf of Mailprotector Support are legitimate. If your email filtering flags these messages as possible impersonation, they are safe to release and trust.
We will update this notice when we return to our standard domain.
