We have a mixed environment of Office 365 PC and Office 2011 MAC users, when we received large file attachments on the PC's they download in a timely fashion but the MAC users have to wait ages. Often hours and often they never download. Is this a known problem? why would the MAC users be so slow compares to the PC users? They are on the same network and all have gigabit Ethernet connections.

I have previously posted this on the Office 365 forum and they have requested I post this here instead.

Also, is there a new version of the Office 365 software due for the MAC anytime soon?

TIA
