Hello again!
So I want users to be able to open and use any existing PST files that have but not be able to create any new PSTs or not be able to add any new items to their existing PST's.
EV outlook add-ins are yet to be deployed for these users, but due to some environmental constraints I want to ingest these users PSTs manually. There aren't that many and so doesn't need any third party tools, but I do want to take a 'copy' if the users PST and ingest it (probably via EVPM). So once I have the copy I need to avoid the user adding any new content into their PST or even create new ones that I might then miss (so effectively, ahead of taking a copy of their PSTs, I need to set any existing PSTs to 'read only' and prevent any new PSTs being created). Once the PST has been ingested then we'll go around and delete them all.
From what I've read it would seem that PSTDisableGrow would prevent uses from both adding items to existing PSTs and alow creating new PSTs but I'm not sure if it will also prevent a user from mounting and existing PST?
I know I need to add the PSTDisableGrowAllowAuthenticodeOverride setting once the EV Add-in has been deployed
thanks C
