Eseries / Communicators :: E7 Mail App Slow To Open Mails With Attachments?

I have a brand new E7 configured with my corporate Exchange 2003 server account and my private gmail. E7 runs the most current SW P1.1 014.002.263.03.Mail/calendar/contacts sync works but opening a received mail with any attachment listed (even how tiny, like 1kb jpeg) on the mail application takes ages. If I click on a message on the mail list it can take upto 30 seconds before the screen shows the message. During the time the phone freezes, even the hardware buttons are not responding. The symptom is the same on Exchange and Gmail accounts. Messages not having any attachments open in about 4 secs. I have tried to delete the accounts etc. but no joy.The mails are received as push, I have tried also scheduled receiving, offline mode etc. but the speed is the same. Is anyone else seeing this and is there anything to be done? The speed of the mail application is so poor that it prevents me to use the E7 as the business phone.
