Every time an item (email/appointment etc) is tracked within Outlook using the Outlook client for CRM 2015 a dialog with a progress bar pops up saying, "Contacting CRM", followed by "Wrapping up". This takes away focus from the Outlook window (and anything else you're doing) and nothing can be done until the messages go away. If you're tracking large emails or have a lot to track this can take some time. It has only been introduced with the 2015 version of the client and it needs to be taken away. The user should not be informed that a background track is happening. Why do they need to know? More to the point, why should it stop them doing anything else while it does it's thing.
