Hi, I need configure size message limit to messages sending between same database mailbox to all its mailboxes.I was configure on Global Settings, but this apply to all exchange organization, the question is:is there another way to configure size message limit for mailbox server than configure by mailbox only??Hub transport settings have to default recieve connector but neither apply to mapi client.any ideas ?regards, Johan M.

Setting the transportconfig:http://technet.microsoft.com/en-us/library/bb124151.aspx MaxSendSize and MaxReceiveSize will have the same effect as setting it by server ( for all mailbox servers) since all messages must pass through the hub transports, even those sent between mailboxes on the same store. You could also pipe with powershell the entire mailbox server ( get-mailboxserver) or by database (get-mailboxdatabase) to the set-mailbox command and set for all the mailboxes for server or database.Note you should set the send and receive sizes the same.More info:http://technet.microsoft.com/en-us/library/bb124345.aspxManaging Message Size Limitshttp://technet.microsoft.com/en-us/library/bb123981.aspxset-mailboxhttp://technet.microsoft.com/en-us/library/bb124924.aspxGet-MailboxDatabasehttp://technet.microsoft.com/en-us/library/bb123539.aspxGet-MailboxServer

thanks for you answer Andy, but I have 10 companies and each have its ownHub Transport Serverunder same Exchange Organization and its size limits policies in some cases are differents.I found the only solution configuring by PowerShell each user mailbox for Mailbox server to goal the requeriment.any comment ?regards.

Yep, in that case, piping by server to set-mailbox and setting the send/receive limitper mailbox on thatserveris really the only way to accomplish that.

Done. Thanks A lot.
