The Enterprise Vault collection fails at the point of writing the PSTs; repeating the error "Error while writing mail file XYZ.pst, deleting mail file and rewriting".
Error while writing mail file EVJournal-0.pst, deleting mail file and rewriting
The issue is caused by Outlook PST API not being able to insert items into a PST on the local Clearwell appliance. Either there is a GPO preventing the creation of PST files when using Outlook 2010 or a corrupt /missing Outlook profile for the Source Account.
1. Remove the PST writing restrictions from the Group Policy Objects (GPO) being applied to the Clearwell appliance.
GPO example that will prevent the writing of PSTs:
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\12.0\outlook (Outlook 2007)
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook (Outlook 2010)
Verify the REG_DWORD 'DisablePST' is not present or the value is 0x00000000 (0)
2. Add the Source Account Outlook Profile
a. Logon to the Clearwell appliance using the Source Account assigned to the Enterprise Vault Source.
b. Run the registry file to place the user's Outlook profile into the registry.
