Sending emails highlighted one omission in Windows Phone 7 copy and paste. Most of the time it didn't bother us, as the software recognises email addresses and phone numbers and responds appropriately when you tap on them offering to send a mail to the address or call or text the number. We came unstuck when wanting to forward a portion of an email instead of the whole thing, though. Microsoft has promised to add copy and paste in a software update due in the New Year though.
Both Windows Live and Google Mail let us send and respond to meeting requests; in Windows Live you can accept or decline from within the email application, but Google Mail loads a web page with accept or decline links. It's slightly clunky but works. We were impressed with the phone's attachment support. We could open documents from within a zip file, and edit Word, Excel and PowerPoint files. PowerPoint presentations displayed flawlessly, although you can only edit files saved in the newer .pptx format. Excel spreadsheets would display charts and tables were present and correct in our test Word file, but embedded graphics wouldn't display.
