When using Key Management (KM) Server and Certificate Server to issue V3 certificates, some mailboxes may not be able to obtain a certificate. After submitting a security token from Microsoft Outlook, the following error message is returned:
Additionally, an event similar to the following is logged in the application log of the Exchange Server computer:
The message from the Microsoft Exchange Key Management Server could not be processed. Contact your administrator for a new security token, and set up advanced security again.
Event ID: 5005
Description: Mailbox "o=Orgname, ou=Sitename, cn=Recipients, cn=Subcontainer1, cn=Subcontainer2, cn=Subcontainer3, cn=Mailbox" has failed being enabled or recovered.
Certificate Server 1.0 enforces a 64-character limit on the Subject of a certificate. The Subject is a concatenation of each Relative Distinguished Name (RDN) within the Distinguished Name (DN). In the example above, the DN is "o=Orgname, ou=Sitename, cn=Recipients, cn=Subcontainer1, cn=Subcontainer2, cn=Subcontainer3, cn=Mailbox". The limit is placed on the concatenation of "Orgname, Sitename, Recipients, Subcontainer1, Subcontainer2, Subcontainer3, Mailbox", which is (7 + 8 + 10 + 13 + 13 + 13 + 7). This exceeds the 64-character limit, and therefore Certificate Server cannot generate a certificate for this mailbox.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
