We are looking at using 365 to initially deploy Office Professional Plus.
We're finding a few niggles with things like dirsync and creating an install image where we're sure we're doing nothing wrong, and a million and one other people on Technet seem to have similar issues, but there is no obvious resolution, and Microsoft technical support seem, well let's just say they aren't great.
So we're wondering whether it's worth engaging an external company to do a sanity check and hopefully have a more direct/useful route into Microsoft.
