Missing OAB Template Language ID's cause generation problems.

  • Article

Under certain circumstances the OAB Generation process can fail when OABGen.dll is able to query the Address-Templates container in the Active Directory, however is unable to read any attribute values from the multi-valued attribute "msExchTemplateRDN's". This active directory attribute contains the language id's that are necessary for building the OAB Template files. If these language id's are missing from this attribute it will cause the OAB Generation process to fail when building the template files. The new check has been added to the templatetest and looks like this:

Total Address-Template Language ID's found: 49

Depending on the situation on how these language id's were removed, you should be able to modify the msExchTemplateRDNs attribute on the CN=Address-Templates objects and add all of the language id's back for each of the templates that are found in check 2 of the templatetest. The values should show as followed:  

401 
402
403

And so on...
