Yes, you can restrict and override the global setting in #1, only if it were
less, not more than the global, based on the "the lowest value takes
precedence" rule stated in the help files. Read below for more info.
For #1:
From the help files:
"Maximum number of recipients: This field specifies the maximum number of
recipients in a message. The default is 5000. The valid input range is 0 to
2147483647. If you clear the check box next to Maximum number of recipients,
no limit is imposed on the number of recipients in a message. Microsoft
Exchange Server 2007 treats an unexpanded distribution group as one
recipient."
This affects an individual's single outbound email, which also affects a
distribution group to the 5000 limit. If you change it, it affects all
individuals.
#2,
From the help files:
"Maximum Recipients Select this check box and use the corresponding text
box to specify the maximum number of recipients to whom the mailbox user is
allowed to address an e-mail message. You can enter a value between 0 and
2,147,483,647. Clear this check box to remove this limit."
Generally speaking:
From the help files regarding Max Recipients per message:
"Maximum Recipients per Message Restrictions: It can take a significant
amount of time for a Hub Transport server to route messages that are
addressed to a large number of recipients. As a result, this may affect the
performance of the Hub Transport server, which could impact the overall
message delivery in your Exchange organization.
To eliminate this risk, you can restrict the number of recipients that are
allowed per message. Although you can configure this restriction at the
mailbox level, you can also configure it at a higher level, such as the
organization level, connector level (only for Receive connectors), and Hub
Transport server level. Generally, it is a best practice to configure this
setting at a higher level and use the mailbox-level configuration only for
exceptions. For more information about the different levels at which you can
configure this restriction, as well as a list of default values, see
Managing Message Size Limits."
If the Global or other settings conflict, depending on what service pack
version is installed on Exchange 2007, however each version goes by the "
the lowest value takes precedence" rule.
======
"Global limits These limits apply to all Exchange 2007 and Exchange Server
2003 servers that exist in the organization. The global message limits are
stored in the Active Directory directory service.
In the release to manufacturing (RTM) version of Microsoft Exchange Server
2007, it is common for the organization limits and the global limits to
conflict. When the organizational limits and the global message limits
conflict, the lowest value takes precedence. In Exchange 2007 RTM, you must
use Exchange System Manager on an Exchange 2003 server or the Active
Directory Service Interfaces (ADSI) Edit tool to modify global message
limits. For more information, see How to Modify Exchange 2003 Global Message
Size Limits in Exchange 2007 RTM.
In Microsoft Exchange Server 2007 Service Pack 1 (SP1), the condition that
cause the organization limits and the global limits to conflict has been
eliminated. Changes that you make to the organizational limits are
automatically copied to the corresponding global limits. In Exchange 2007
SP1, you can modify the organizational limits by using the
Set-TransportConfig cmdlet in the Exchange Management Shell, or by
configuring the Hub Transport server organization configuration properties
in the Exchange Management Console."
