BB Software :: Push Mail Not Working Properly For Windows?

This is quite an old subject, but it seems to be a recurring problem across versions of Windows Live Messenger handheld client software and Blackberry Internet Service server software. For some time, I used to have no issues with Live Messenger and Push Mail from Hotmail. Now, once again, I am having a huge delay, of several hours, when logged on as "Online" to Windows Live Messenger.

What makes me believe that it is not a Windows Live limitation, by design, due to protocols and notification mechanisms in use, is the fact that I can receive both push mail and instant message notifications, immediately, as long as I am logged on to Windows Live Messenger as "Busy" or "Away". If the protocols in place allowed notifications to only a single service at a time, I believe it should not work regardless of the status on Windows Live Messenger.

I have been using Hotmail for quite a while and most of my friends use Windows Live Messenger, so I would like to keep both working in my BlackBerry. I understand BlackBerry has a commitment to offering broad compatibility, great stability, and better integration than other solutions on the market that appeals to fancy user interfaces and forget about objectivity. Having a mobile platform that can keep both the corporate and consumer world happy is definitely a great advantage. There are several loyal users that would like to keep sharing the proficiency on a common user interface for business and personal use.

I do not often post messages to online forums, but this is an issue that has been annoying me for quite some time and I am really looking forward to a solution. Is anyone experiencing the same behavior with Windows Live Messenger lately? Is RIM looking for a solution?
