Then went through the following KBA for a "VSS_E_PROVIDER_VETO" error message and goes into more detail about the diagnostics and solutions:
https://support.quest.com/SolutionDetail.aspx?id=SOL79141
Unfortunately this didn’t resolve the issue.
Additionally the returned error number (0x80042306) points to a 3rd Party VSS issue (in this case it is the Smart Copy on the Dell Equallogic PS6100XS) i.e. when a VSS provider blocks the creation of the VSS snapshot.
A restart of the Volume Shadow Service should fix this issue. If this doesn't resolve the issue, please try following steps before retrying the
backup:
1. The writer may be in failed state, so to verify the writer status run the following command through the command prompt on the Server:
vssadmin list writers
Ensure that no writers in the list show any errors. In case a Writer is in an error state, reboot the server to make the writer stable again.
2. To verify the snapshot providers, run the following command through the command prompt on the Exchange Server:
vssadmin list providers
Check the output and see how many providers are installed.
There is a possibility that too may VSS providers are performing the same action at the same time.
You can also see the list of providers also under the registry:
HKey_Local_Machine\system\CurrentControlSet\Services\VSS\Providers
In this case there was the Microsoft and Dell’s Smart Copy VSS Providers listed and we resolved the issue by disabling the Dell’s Smart Copy VSS Provider.
NOTE: Please backup the full registry before making any changes and if you are not confident to make any changes, then please raise a case with Microsoft as we cannot be made accountable for any adverse effects on your system from any changes made. Thanks you.
