Proxy settings with Outlook 2007 client aren't persistent

The Outlook 2003 client proxy settings used to be persistent; when a user traveled all he had to do with Outlook 2003 was add or remove the check under the Connections tab to enable or disable the proxy settings depending on whether they were on-site or off-site.

With the Outlook 2007 client, the proxy settings are no longer persistent.  Now when a user removes the check as they used to do when back in the office the proxy setting go away.  When they again travel, they have to remember what to put where in the proxy settings dialog box or have it written down somewhere.

Is there a fix to again make the proxy settings in Outlook 2007 persistent?

Thanks for any help!

Kindly let me know the reason the users are deselecting the Exchange Proxy settings from Outlook in office.
Is this done to ensure that internally users connect over TCP rather than HTTPS?

If yes then you can try below steps for same:
To make that happen, kindly keep the selection of Exchange Proxy settings in Outlook.
Deselect the option in Outlook client, "On fast networks, connect using HTTP first, then connect using TCP/IP"

You are correct.  Internally they connect TCP.  When traveling off-site they need to connect over HTTPS.  With the proxy enabled with both TCP and HTTPS, all the time, we have found that when users are on-site, Outlook takes a performance hit.  That's why with Outlook 2003 it was convenient to take the check off the proxy settings.

Tried your steps: "De-select the option in Outlook client, On fast networks, connect using HTTP first, then connect using TCP/IP".  Closed and reopened Outlook and the proxy settings were again missing, other suggestions?

I reread the proposed solution posted and found I misunderstood how to do the fix.  As I read it now, you are saying to remove the check from "On fast networks, connect using HTTP first..."  and leave the check on the Proxy settings.  We will try this out.
