How can we ensure that MNE is running under MAPI over HTTP?.
The temporary MAPI profiles that are created by MNE are exclusively RPC based, either RPC over TCP or RPC over HTTP. MNE currently does not have the capability to dynamically create a MAPI over HTTP profile.
See below steps to ensure that MNE runs under protocol MAPI over HTTP:
1.- Create a MAPI profile via the Windows Control Panel (or Outlook). Remember to disable cache mode.
2.- Set the following MNE parameters:
RPCAdminMapiProfile="Outlook Profile Name"
Note: If you are running a version of Outlook that supports RPC over HTTP then the profile will be configured to use RPC over HTTP. You will need a newer version of Outlook which supports MAPI over HTTP for this to work.
