On Friday morning the MiaB server (v0.43) did an unattended-upgrade. After that, Outlook2016 was no longer able to connect to send outgoing email. Webmail, and mobile clients continued to function properly.
Has anyone else encountered this issue?
The MiaB status page reported that a reboot was necessary. I am awaiting to hear from the users if the reboot has solved the problem … in the meantime, has anyone else encountered this?
