Users with 'reader' access level to other Domino Mailbox databases are getting the error 'Notes error: Unknown OS error' and 'Module: EVLAUNCHDOCUMENT, Line: 76' trying to retrieve archived emails from other mailbox database.
This is the error given to the users having 'reader' level access to others Domino Mailboxes
Since Enterprise Vault 9.0.1 any retrieve action actually writes temporarily the retrieved items into the Domino Mailbox hidden view EV26C5E2CCF2B9267C.TempItemsV1.
Other users with 'reader' access level cannot 'write' any data into the hidden view with the result that the retrieve does not work.
At the moment the unique workaround is to give 'editor' permissions level instead of 'reader' to other Domino mailbox database, it is needed to execute an Enterprise Vault provisioning task after the permission level change.
This issue has been addressed as part of the following release:
- UserA and UserB
- UserA having 'reader' access level to UserB domino mailbox
- UserA having 'read' permissions to UserB EV domino archive (synchronized by the provisioning task)
- UserA is getting the above error trying to retrieve archived emails from UserB domino mailbox
