I have a complex folder structure within my own Inbox (total 6 GB of emails). In general the behaviour of z-push 2.3.3 (and prior) and Outlook works very well.
But I have some issues with moving folders. If I move folders from one sub-folder in my Inbox to another sub-folder in my Inbox (with Outlook) it might happen that the folder moves with Outlook 2016, but in the backend it remains. In the end I am out of sync.
Outlook says during the move: “connected – last sync of this folder was at xx:yy” or even worse “Disconnected – last sync of this folder was at xx:yy”.
After the move operation is finished (at least I guess so), Outlook shows that all folders are in sync – connected state again.
I have a lot of folders which are smaller (< 1 MB) – in general no issue. But it seems to start with bigger folders… I am not sure what the reason is. I am not sure if the problem is related to the folder size… And I can’t find any errors in the log files…
I have seen issues with moving mails before as well ... (getting out of sync) but folders are a much bigger problem.
