Some people commented recently about an “issue” they see when running the Enterprise Vault 9 Deployment Scanner. They see a message indicating that Sharepoint 2003 was detected per this message :
Microsoft SharePoint Portal Server 2003 has been detected, which is no longer supported. For the latest information on the supported versions of Microsoft SharePoint Server see the Enterprise Vault Compatibility Charts at http://entsupport.symantec.com/docs/276547.
Unfortunately that is the way that things are. Enterprise Vault 9 no longer has support (ie the code was removed!) to archive or process Sharepoint 2003 servers. The options available to you then, at this time are :-
a/ Upgrade Sharepoint
b/ Remove your Sharepoint data/targets.
