Updating a client's mail server from CU7 to CU8 and an error at the end involving access denied to a certain folder caused a failure and we had to restore a backup and run the update again, this time it was successful. When we looked later we noticed that several of the folders under c:\program files\microsoft\exchange\v15\clientaccess have no owners now. We can manually set the ownership, but is this intentional?

Hi,

I recommend you check if there is any error information in Exchange setup logs. What's more, I would like to know who is the owner of these problematic folders under c:\program files\microsoft\exchange\v15\clientaccess before upgrading.

Best regards,

We did have an error the first attempt, but we rolled back and did it again without an error. However, the ownership changed. Before install, the owner was SYSTEM, afterward it is unknown. Everything appears to be working correctly as well.

Just following up as no one has responded since my last post. Anyone ran into this issue?
