How to Set Message Size Limits in Exchange 2007

I have a maximum receive and send size of 25 MB set in Organization Configuration\Hub Transport\Global Settings\Transport Settings.

Does a Receive Connector's maximum message size over-ride the Transport Settings limit?
Can the same be said about a Send Connector?

Thank you

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

No settings not override.

You must enlage trasport settings, connector setting and mailbox settings.

Some as here http://www.msexchange.org/articles-tutorials/exchange-server-2007/management-administration/exchange-2007-message-size-limits.html

According to this article http://www.msexchange.org/articles-tutorials/exchange-server-2007/management-administration/exchange-2007-message-size-limits.html the lowest settings take precedence. So what if my Receive Connector has a max setting of 25 MB, but I need a mailbox to be able to receive up to 50 MB emails? Do I have to increase the connector's limit to 50 mb and then set all mailboxes, individually, to 25  MB, except for the one I want at 50 MB? That does not seem practical?  I think I am misunderstanding something?

Yes understand right. Without enlarging connector limit imposible to send from one mailbox 50Mb mail.

That's what I am trying to understand. For example, if I have 1000 mailboxes and I need 1 mailbox to send\receive up to 50 mb but all others to send\receive only up to 25 mb, then I have to increase the connector's limit to 50 mb and set the other 999 mailboxes to 25 MB, each one individually?

You can configure all Limits using batch:

Get-Mailbox | Set-Mailbox –MaxSendSize 25000000

or use it more flexible changing only users from one database or user with special group

There are flexible batches:

Get-User -Filter "Department -eq 'Customer Service'" | Set-Mailbox -MaxSendSize 2097152
or
Get-Mailbox -OrganizationalUnit "Marketing" | Set-Mailbox -MaxSendSize 2097152

Oh. This commands must be entered from Exchange Shell

So setting a send and receive limit on a mailbox will not override the connector or global settings, exchange will simply use the lowest setting available?
