WE are using snapmanager for exchange V18.104.22.1681, and we are occasionally now getting errors on our backups which are failing. The exchange server we use is exchange 2007. The error we get is linked to the volume shadow copy service and the reports logs the following error message :
Error in calling VSS API: Error code = 0x8004230f
Error description: VSS_E_UNEXPECTED_PROVIDER_ERROR
We restart the snapdrive service which then corrects the situation, the backup next time runs successfully. The server is running on a windows 2008 service Pack 2 server.
We get these messages once a week now. Any reason why.
Also are we running the latest snapmanager for exchange server , or is there a latest one.

Check the SM logs to see the time of the failure then check the Windows logs to see if anything else was going on at this time.
I've seen this when the OS is being backed up at the same time the SM job is running and VSS gets screwed or any other process
If it literally is happening once per week on the same day this will be your problem

Based on my research, the error code 8004230f means: The shadow copy
provider had an unexpected error while trying to process the specified
operation. Generally this issue can be caused the following factors:
1. Certain VSS DLLs are not registered properly
2. There is a problem with shadow copy provider
I suggest we perform the followings to troubleshoot the issue:
Step 1: First please apply the latest VSS package (KB940349) on the server.
Reboot the server for the package to take effect
Step 2: Re-register the VSS related DLLs
To do so, type the following commands at the command prompt. Press ENTER
after each command.
cd /d %windir%\system32
net stop vss
net stop swprv
regsvr32 /i swprv.dll
regsvr32 /i eventcls.dll
Note: The last command may not run successfully.
Try Backup and see if the error still occurs.
Step 3. If the issue persists, go to the following registry key:
Import this key for backup
Delete Key "VOLUME"
Reboot the system
This will recreate the "VOLUME" key
