We just updated our grommunio appliance via GUI. After reboot and connecting with Outlook 2021, we have a very strange behavior.
When Outlook is open and a new mail arrives, unread counter goes one up, which is correct. But the inbox shows that mail as being from yesterday and it's shown 2 times, sometimes only once.
When clicking on one of those strange mails, one can read them, but when clicking on another mail in the inbox, all mails in the inbox vanish.
When I reload the list of mails through filter changes (clicking unread, clicking all again) or opening another folder and back, the list is fine and the new mail is shown correctly.
Anybody else having the same issue?
