Public folder archiving stopped on EV9

Hi

About a week ago Archiving of Public Folders stopped.

Evault 9.4 on windows 2003 R2 sp2 and exchange 2003 sp2 on w2k3 R2 sp2.

Using dtrace I see this errors for every public folder.

I've add the vault account as owner to the public folder (and subfolders).

I believe the archiving stopped after windows updates, but I might be wrong.

Mailbox archiving works (same servers, and accounts used).

It seems to be the same problem as here: https://www-secure.symantec.com/connect/forums/ev9-no-new-items-public-folder-archiving

Please help.
