The folders that were previously created can not be seen in Virtual Vault structure in Outlook after a Permissions Zap has been performed on the archive.
During the permissions zap, the AutoSecurityDescriptor field is removed from the folders; entries in the ExchangeMbxArchiveFolder table in the Vault Store database. When this value is empty, folders in Virtual Vault will not be displayed.
In the .ini file created for the Permissions Zap, the following parameter must be added: ResetArchiveFolderPerm = 1.
If this is added, and the users' Vault Cache is synchronized, the folders will not yet appear, but the AutoSecurityDescriptor entries will be repopulated in SQL in the ExchangeMbxArchiveFolder table.
A partial reset of the Vault Cache to download a new MDC file will bring the folders back into display. In some cases, a full reset was necessary.
Example:
[Directory]
DirectoryComputerName=ev-exch
SiteName=TRN
[Mailbox]
DistinguishedName = /o=evrpslab/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=User 1
ResetArchiveFolderPerm=1
