Exchange Server's 32 KB Rules Limitation |
| |
Exchange 2003 and older supports just 32 KB worth of rules. If each rule is
small and simple, you might get about 50 - 70 rules when using Outlook
2002 and older. Outlook 2003 (and up) uses Unicode when writing the rules and
this requires more space per rule, leaving most users with about 20
rules. In Outlook 2000, you could force rules to be client rules, which are stored in Outlook. This would allow you to have many more rules. This does not work in Outlook 2002 and 2003 (and up) - all rules, both client and server, are stored on the Exchange server and subject to the 32 KB size limit. In Exchange Server 2007/2010 the limit is higher - 64KB by default and configurable up to 256KB. This change will allow in the neighborhood of 100 rules, or about 90 more than I want to manage in the Rules dialog. If you use Exchange 2007/2010 and need more space for rules, speak with your administrator and ask him to raise the limit. If you're an admin and don't know how to change the rules, use the following cmdlet in the Exchange management shell to raise the limit to 256KB.

better rules handling. |
