Outlook/Windows Smartphone edition Keeping us.."safe&qu

[da5idee]

Hoping I posted this to the correct location...

So I have a treo 750 and have routinely email cabs to an account that I have set up to be checked by pocket outlook on the device and have never had an issue...

So I also have a blackjack and I tried the same exercise and got the following message when clicking on the attachment link of the cab in an email...

"Error - The attachment is of a file type that could be unsafe. Messaging will not open this attachment"

any clues, or has anyone else come across this b4?
