I'm having trouble with our 3rd party add-in buttons being available when opening EV shortcuts and replying or fowarding them. We tried the below reg key which works on some clients, but not all clients. I can't seem to find the common element here that causes the error below. Our policy is set to download messages in .msg format
[HKEY_CURRENT_USER\Software\KVS\Enterprise Vault\Client]
"DisplayItemsUsingOOM"=dword:00000001
With this key in place, some clients do see the add-ins and some don't. I thought it had something to do with cached vs. non-cached mode, but I have tested on PC's working in both modes sucessfully. Any insight anyone can provide would be greatly appreciated.
