EV Outlook connection states

Often when troubleshooting Enterprise Vault Outlook client issues we'll see issues related to how Outlook is connecting to Exchange.  There are several ways that people can configure Outlook, and EV needs to know about them.  Here is some information which I use regularly.

Outlook Connection mode often appears in client traces, but at the moment it is just “a number”.  You can decode them as follows :

                        evConnectionUnknown = 0,
                        evConnectionOnline = 1,
                        evConnectionOffline = 2,
                        evConnectionNoExchange = 3,
                        evConnectionDisconnected = 4, 
                        evConnectionCachedOffline = 5,
                        evConnectionCachedDisconnected = 6, 
                        evConnectionCachedConnectedHeaders = 7,
                        evConnectionCachedConnectedFull = 8,
                        evConnectionCachedConnectedDrizzle = 9

When you see them in client traces you would be looking for things like :

05/12/2007 11:47:43.388[3084]: CDesktop::GetOLConnectionState: 0x0
05/12/2007 11:47:43.389[3084]:     Outlook Exchange Connection Mode: 6
05/12/2007 11:47:43.390[3084]: ~CDesktop::GetOLConnectionState: 0x0

And

05/12/2007 11:48:37.235[3084]: CDesktop::GetOLConnectionState: 0x0
05/12/2007 11:48:37.235[3084]:     Outlook Exchange Connection Mode: 8
05/12/2007 11:48:37.236[3084]: ~CDesktop::GetOLConnectionState: 0x0

I think that 9 is the only unusual one.  This is where you are in cached mode with Outlook, and you have the option enabled to download headers, and then full bodies later.  To check if you are in this mode, you can visually look at the Outlook status bar  at the bottom right hand side of Outlook

When you’re in headers then body (ie “9”) you would see "Connected to Microsoft Exchange (Headers)"
