Hi, we are using Exchange 2016 and started getting this error:
Already checked permissions, Network Service has this set on Data\Diagnostics folder:
As for the files which give 0x000000005 error - I don't see their ACL due to lack of permissions (can only change owner), every file has guid-like name (something like "326ace4f-20f3-cb47-b35d-21e3888d0de").
I would be grateful for any help.
