Useful information for all Enterprise Vault administrators out there is that Microsoft have released Office 2013 Service Pack 1:

The updates are a whopping 643 Mb and 774 Mb respectively.
Why is this important to Enterprise Vault Administrators? Well, it is something that can of course be tested with the Enterprise Vault Outlook Add-in, but 'we' should all wait until Symantec have given the 'nod of approval' before going ahead and installing it in a production environment. There might be as yet unforeseen issues with the Enterprise Vault Outlook Add-in and the service pack.
Interested to know though if anyone has any feedback, please let me know.
