Disable creation of VPN "*Session" credential in Credential Manager without disabling all of Credential Manager?

Question

Is there a way to disable creation of the VPN "*Session" credential in Credential Manager without disabling all of Credential Manager?
I know that you can disallow storing all domain creds in Credential Manager by setting the following registry entry to 1 (but this doesn't fix my issue):
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa
Value Name: DisableDomainCreds
Value Type: REG_DWORD
Value: 1
On my Windows 8 Enterprise workstation, I use mapped drives with one domain account and Outlook with a different domain account. Using the fix above fixes my issue with mapped drives (after sleep mode, reconnect to VPN and my mapped drives won't reconnect until
I delete the '*Session' credential) but then I cannot use Outlook at all.  Note: I do not log on to Windows 8 with either of the domain
accounts mentioned above (I use a local admin account) and I do not 'save my password' in Outlook.

I should clarify my question: Is there a way to disable creation of the VPN "*Session" credential in Credential Manager
without disabling all domain creds in Credential Manager?
On my Windows 8 Enterprise workstation, I use mapped drives with one domain account and Outlook with a different domain account.
Normally I can use Outlook if I am connected to the vpn and I can use it if I am not connected to the vpn.
Normally I can use the mapped drives if I am connected to the vpn and I I can use the mapped drives if I am not connected to the vpn.
The vpn is essential for me to do my work for reasons other than the mapped drives and the usage of Outlook, but I need to be able to use the mapped drives and Outlook whether I am connected to the vpn or not.
Let's say my two domain accounts are these: drive-account and outlook-account.  I must use the outlook-account for the connection to the vpn.  When I connect to the vpn, it creates the '*Session' credential in the Credential Manager for outlook-account,
the mapped drives disconnect and they will not reconnect until I delete the newly created '*Session' credential.  The error is 'An error occurred while reconnecting <drive letter1:> to <\\network\path>  Microsoft Windows Network: The
local device name is already in use.  This connection has not been restored.'  Further evidence that it is the '*Session' credential causing the failure to reconnect is that I have two mapped drives and if I disconnect one of them and try to reconnect
the other one, I get a different error, 'An error occurred while reconnecting <drive letter2:> to <\\network\path2> Microsoft Windows Network: Multiple connections to a server or shared resource by the same user, using more than one user name,
are not allowed. Disconnect all previous connections to the server or shared resource and try again.  This connection has not been restored.'  Manually recreating that first connection then allows me to get back into both, but I should not have to
manually delete and recreate a mapped drive every time my computer goes to sleep.  At least the manual deletion of the '*Session' credential is slightly less intrusive, but I'd still appreciate if there is a way to disable the creation of the '*Session'
credential without disabling all domain creds in Credential Manager.  As I have said, if I disable domain creds using the registry fix some have suggested, I do not get the drive errors (after sleep mode and reconnecting to vpn), but I cannot use Outlook
at all.
Note: I do not log on to Windows 8 with either of the domain accounts mentioned above (I use a local admin account) and I do not 'save my password' in Outlook.
