The items I'm sending are backing-track arrangements of songs for the new musical that I'm working on - when I make changes to the (faux)orchestration of songs still being worked on I send the new version(s) to my collaborator and/or script editor. The 'packages' vary little in size - but Hotmail's acceptance of same seems to vary considerably from day to day. Is there or is there not a set limit - and if there is and I adhere to it in future, will Microsoft stick to its side of the bargain?

Thanks - Mike Atkinson.
