I run Outlook 2010 in a virtual machine running Windows 7. Networking is provided through the host. Outlook connects to an Exchange server.
When the host's IP address changes (e.g. moving to a different wifi network), this breaks Outlook's connectivity. I haven't investigated in depth, but it seems to stubbornly retain a TCP connection and not start a new one. The status bar at the bottom keeps displaying “This folder was last updated at <time>” and new emails aren't downloaded.
Pressing the “Update Folder” or “Send/Receive All Folders” buttons doesn't help. Switching to offline mode (“Work Offline” button) and back online doesn't help.
Sometimes, eventually, Outlooks reconnects. But that takes minutes or hours. How can I instruct Outlook to reconnect now?
Killing Outlook and restarting it works, but it's disruptive. This issue is specific to running Outlook in a VM, or presumably behind a gateway whose IP address changes: if the IP address of the Windows machine itself changes, Outlook does reconnect correctly.
