Basically as above, I use a windows mobile at the moment so linked with outlook etc wia exchange server also hotmail/gmail etc. When someone sends a word doc it opens ok, would the same be true of an Android equiped phone?

 

There's an app for that!

I think its $9.99 and called documents to go, you can open and edit, if u just want to open and read android should do that out of the box with google docs.

 

There's some information here you might find handy exchange server active sync setrup - Android Forums
