Can master users retain private \Seen flags ?

[Aki Tuomi]

I don't see why it's so difficult or unwanted solution to create a mailbox shared and then access that as a shared folder from bob's and alice's account?

Is it because you found this handy guide and now you cannot see any other solution anymore?

You would not even need the complicated way of logging in if you'd use shared folders instead. Users could log in the normal way and look into Shared/sales folder.

Or am I missing something??

I would like Alice and Bob to retain private \Seen flags on sales at example.com. I know I can achieve that with INDEXPVT on shared or public mailboxes but I am not 100% happy with this solution because:

But I am not sure another email client is able to do that (on a mobile phone for example).

I achieved that but I don't know how to retain private \Seen flags so that Bob doesn't see an email as read even if Alice has marked it as read before.
