Determine the Exchange Schema Version

 

Applies to: Exchange Server 2010 SP3

Topic Last Modified: 2012-12-26

To verify that the Exchange schema version has been updated correctly, determine the value of the rangeUpper attribute on the property page of the ms-Exch-Schema-Version-Pt schema attribute.

To look up the value of the rangeUpper attribute, use a tool such as ADSI Edit, LDP.exe, or DSQuery.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Organization Management” entry in the Understanding Management Role Groups topic.

  1. Sign on to a domain controller in your Active Directory forest.

  2. Click Start, click Run, type ADSIEdit.msc, and then click OK.

  3. In the ADSI Edit console, right-click ADSI Edit in the navigation pane, and then click Connect to.

  4. In the Connection Settings dialog box, select Schema in the Select a well known Naming Context list, and then click OK.

  5. Expand the schema node in the navigation pane, and then click CN=Schema,CN=Configuration,DC=contoso,DC=com.

  6. Right-click CN=ms-Exch-Schema-Version-Pt, and then click Properties.

  7. On the property page, locate rangeUpper in the Attribute list.

  8. Verify that the value is correct for the expected Exchange Schema.
