As some of you might have noticed, if you have the Outlook desktop client installed and Outlook open, and then open CRM using IE, you will loose some web-specifics like the "Settings" menu and other addons specified in the sitemap or isv.config.xml as "web".
This is due to the fact that these files are downloaded to the client by IE when Outlook is started and these are then cached by IE. When the same URL is opened, IE recognizes these files, and does not download any new files, hence you get the Outlook-client specific.´
How to solve this? IE bases its caching on the url so you just have to install the crm-outlook-client to one url and use the webclient for the other. Note that you can even use the IP adress as one of the url:s, since IE doesn't resolve the name when checking for cache-hits.
