Email replication, diff between server and local

Dear experts,They are few of my users who having problem with replications.

All of the users are working locally, and they do replication in schedule basis every 5 minutes.

Problem.

sometimes, when they creating folder in their local, the folder is not replicated back to server. this is not happen to all the folders.

Any advise?

Thanks in advance.

Subject: shared vs. private

make sure the folders are “shared” (yellow/orange) and not private (grey)

Subject: The folders are shared

The folders are shared, the only way that I can fixed this is to delete the mail in the server, and create a new replicate in the server based on their local mail.
