Maximum recipient limit has been changed
[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the msExchRecipLimit attribute has been changed from its default value. The msExchRecipLimit attribute stores the value for the global maximum number of recipients for each e-mail message. By default, the value of the msExchRecipLimit attribute is 5000. If the Exchange Server Analyzer finds that the value of the msExchRecipLimit attribute does not equal 5000, the Exchange Server Analyzer displays a non-default configuration message.
The global maximum recipient limit applies to the whole Exchange organization. The value of the msExchRecipLimit attribute limits the number of recipients for a single e-mail message. The global maximum recipient limit affects system messages and non-system messages. System messages include public folder replication messages.
You can also set recipient limits on a per-user basis by using Active Directory Users and Computers. The per-user setting has precedence over the global setting and will override the global setting. By default, the per-user recipient limit is set to use the global maximum recipient limit.
On a Simple Mail Transfer Protocol (SMTP) virtual server, you can set a limit on the number of recipients per message for messages that are received from Internet users. This limit differs from the global maximum recipient limit and from the per-user recipient limit. The global maximum recipient limit and the per-user recipient limit both limit the number of recipients to which an Exchange user can send a message.
To change the global maximum recipient limit to its default value
Start Exchange System Manager.
In the left pane, expand Global Settings.
Right-click Message Delivery, and then click Properties.
On the Defaults tab, under Recipient Limits, click Maximum Recipients, and then type 5000.
Restart the Microsoft Exchange Information Store service.
