Some Outbound and Marketing customers may see incomplete or missing information in the Mail Log and Paubox Marketing areas of the dashboard, and Marketing pages may be slow to load or time out. Email delivery is not affected. Messages are being sent, received, filtered and encrypted normally throughout. No customer data has been lost — this affects only how recent activity is displayed. We have identified the cause of the Mail Log issue and have a fix in place. We are still investigating the Marketing issue. We will update this page as we have more.

We are investigating reports from some Inbound Security customers that their Inbound quarantines are blank despite mail being marked as quarantined in their mail logs.
-
resolved Jul 22, 2026, 09:06 PM UTC
No defect was identified, no changes were shipped. Two reasons customers may have encountered this: 1) Paubox is shipping improvements almost daily - if something is suddenly unavailable, you may need to log out/back in to refresh your access 2) In order for the Inbound quarantine to display results, "all categories" or at least one category must be selected. If no categories are selected, the page will show no results.

Beginning at 6AM UTC today, Microsoft began presenting an updated certificate on some of their hosted mail accounts, and our outbound servers' list of trusted authorities doesn't yet include the new one. As a result, a portion of outbound emails to recipients hosted on Microsoft 365 are currently being routed through the Paubox Secure Message Center instead of delivered directly to the recipient's inbox. Affected recipients receive a notification with a secure link to view the message in our portal. No emails have been lost and no data security has been compromised — the Secure Message Center fallback is operating as designed to protect message content when direct delivery cannot be verified. We are updating the certificate and should have a resolution shortly.
