In the process of upgrading a customer from 6.5 to 802, we’ve encountered a small but irritating anomaly. We’re rolling out 8.5 clients against an 8.0.2 server.
We’re using a policy to automatically upgrade the mail template of the users when they first authenticate with the upgraded client. We’ve setup the client to notify the admin team when a successful or failed mail template upgrade has occurred. (The failure notifications are useful btw, because they typically suggest the mail template is problematic and needs some elbow grease).
We happily get notifications of success or failure, but on about 10% of the users, we get no notification at all. Manually monitoring and checking theses machines shows that all is well - the template has been upgraded and the user has authenticated and is sending/receiving mail as per normal. Just no automated notification. The users are assigned to the policy via a group. Everything checks okay - it seems.
For a large group of users, this becomes difficult to track and a worrying stat to have to manage. Any ideas - we can’t pin it down.
