Comments on Modified Attributes

ms-Exch-Schema-Version-Pt is an attribute that Exchange uses to keep track of the version of the Exchange schema that is installed. It is not actually set on any objects. As a point of reference, the rangeUpper for the initial release version of Exchange 2007 is 10637, and this value is increased each time new schema changes are made. It typically tracks the major version and (near) build number of the latest changes.

Modified Property Sets

The following attributes have been added to the Exchange-Information property set:

ms-Exch-Content-Conversion-Settings
ms-Exch-IMAP4-Settings
ms-Exch-Management-Settings
ms-Exch-Mobile-Settings
ms-Exch-OWA-Settings
ms-Exch-POP3-Settings
ms-Exch-Transport-Inbound-Settings
ms-Exch-Transport-Outbound-Settings

Comments on Indexed Attributes

msExchMailboxMoveBatchName will now be indexed to improve performance of the administrative console for managing batch mailbox moves.

searchFlags reference:

1 = Index attribute;
2 = Index attribute per container;
4 = Use for Ambiguous Name Resolution (ANR);
8 = Keep attribute on tombstone (deleted) object;
16 = Copy attribute value when copying object (for when using an object as template for another object)
32=tuple index (Windows 2003 forest only)
64 = reserved
128 = confidential attribute (Windows 2003 forest only).

The searchFlags values are additive. For example, 19 = 16 + 2 + 1 = indexed + indexed per container + copy value when copying object.

Best Practices for Schema Changes

We recommend the following best practices for schema changes:

All schema elements have a valid object identifier from a range of object identifiers that are registered and allocated to the vendor.
The Microsoft-recommended naming conventions for schema elements are observed.
Any attributes that are added to the global catalog are required and are widely populated.
Modifications to existing property sets have been approved by the property set owner.
No single attribute is expected to be more than 500 KB. No single object is expected to be more than 1 MB.
Any indexed attributes have unique and widely populated values.
All new attributes and classes contain relatively static and long-lived information.
No Class 88 classes are used.
Schema updating and behavior has been tested in a private forest.

The schema changes that are described in this document comply with these best practices.

Additional Notes

Schema changes that Exchange 2007 SP2 makes to Active Directory are the same as the schema changes that Exchange Server 2010 makes to Active Directory.
