Vault folder permissions disappear

[TS_NG]

Hi,

We face at least twice a week with the following problem:

Vault folder permissions sometimes disappear after running the scheduled archiving task.
Only the mailbox full access permissions can be found in the Permission Browser, the Outlook delegated permissions are missing. After a manual synchronization of the mailbox they are back. Users whose permissions are granted via Outlook cannot access to the particular folders.
It happens more rarely after the 2 EV servers' scheduled archiving task does not run in the same time.

We have 2 EV-servers in 1 site with EV Version: 9.0.4.1097
Operating system: Windows Server 2008 R2 Enterprise x64

Any idea would be appreciated!

Thanks, Gabor

I vaguely remember seeing something like this when I worked at Symantec. I would suggest you contact their support teams.
