Exchange Server 2010 VSS Write Fail

I am having issues with 2010 Exchange Writer . The problem is that it randomly fails out and cause the backups to stop working. I have update both exchange server and the third party Software to the latest and greatest. The Third Party Software I am running for my backups are Barracuda Backups and Mozy Pro. Both third party Software company say their software only use the VSS writer and could not cause it to Fail.   The only error in the event logs I can is below:

A VSS writer has rejected an event with error 0x800423f3, The writer experienced a transient error.  If the backup process is retried,
the error may not reoccur.
. Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.

   PrepareForSnapshot Event

   Execution Context: Writer
   Writer Class Id: {76fe1ac4-15f7-4bcd-987e-8e1acb462fb7}
   Writer Name: Microsoft Exchange Writer
   Writer Instance Name: Exchange Information Store
   Writer Instance ID: {76d70fa8-3edd-4c71-9172-2a858d9b7a67}
   Command Line: "C:\Program Files\Microsoft\Exchange Server\V14\bin\store.exe"
   Process ID: 2996

Mozy Pro reports This Error:

Code: SnapshotError4

An error has occurred when trying to backup using one or more of the volume shadow services.

then basically tells me to reboot my computer.

When I look the event log error, it says to restart the Information Store. What I would like to know is how to stop it from happening.? I should mention that 2007 exchange has no issues with either of these programs.

Call Microsoft. We used for a 2008 server. They may have just sent us an updated package. Also there was no charge for the update or call.
from a command prompt on the server run:

vssadmin list writers

look in the list for anything that has a "error_retryable" - restart the services and try the backup again. If "failed_retryable". Restart the server and try the process again.

There is a hotfix available from microsoft (you need to contact for the hotfix) that is referenced in this article (

We had the same issue with AppAssure and the hotfix resolved it.
