I couldn't post a reply to the thread with the same title so I opened a new one.
A client who I migrated from google is now finding that in shared mailboxes once a user reads a message gets marked read for all other users with access to that box.
In google they stated, that when a user read a message, it will only be marked read in his client, without affecting the others.
I found an article that somewhat relates to this issue, but from the google perspective.
The question is, can users sharing a mailbox and read a message, not affect other users accessing that same mailbox in the sense that if userA reads a message, and userB has not yet seen it, it will not be marked unread?
Can you be more specific about what you mean by a "shared mailbox"? What protocol is being used for mail retrieval? IMAP, POP3, Exchange?
The way your argument is presented, I should be able to look at my email on my PC and trigger the /SEEN flag to be set on all the mail that I've read on that client. Then, any time later, view those same emails from my iPhone (a different mail client) and those same emails all have an /UNSEEN flag set?
Perhaps you should consider a Mailing List instead? Mail sent to the list is distributed to the individual list members. They can read, delete, move to another folder, etc. without impacting any of the other members.
