You receive an error message when you set the permissions of a public folder in an Exchange Server 2003 mailbox

When you use Microsoft Outlook to set the permissions of a public folder in a Microsoft Exchange Server 2003 mailbox, you receive an error message that is similar to the following: When you use Exchange System Manager to set the permissions of a public folder in an Exchange 2003 mailbox, you receive an error message that is similar to the following:

This problem may occur if the following conditions are true:

• You changed the access control lists (ACLs) by using PFDavAdmin, RewriteACL, or another program that uses XML to write permissions to public folders.
• You added the role of Reviewer to the public folders.

If you use XML to write permissions to public folders, the ACLs may become out of canonical order. This problem may occur although the XML is correctly formatted. Additionally, this problem occurs when the following contexts have the same access mask and are written and evaluated at the same time:

• Effective
• Container
• Subitem

These three contexts have the same access mask when an individual user account has its permissions set as Reviewer.
