Zivver Email Server

Zivver is currently monitoring a potential issue with OWA v4 and v5, in which for some shared mailboxes, logging in to Zivver and sending messages (either normal or secure) is blocked by the Zivver add-in.
Zivver is proactively investigating which mailboxes could potentially be affected and what the cause of this issue is. Further updates will be posted on zivver.info
Please reach out to support@zivver.com if your organisation experiences any issues related to OWA and shared mailboxes.
