It is strange they didn't try to make their stuff load faster. People here complain but those people could do something about it. I wonder if it is just a training issue with their programming skills. It seems like all their programs for the Mac have issues or lack very advanced features like their messenger and remote (Beta forever) desktop.
I emailed Craig Eisler about this a long time ago. He was very courteous in his replies and seemed enthusiastic about progressing not only Office, but also developing a few other programs for Macs. He himself is a Mac user.
He forwarded my email to a few software engineers, who were supposedly going to get back to me regarding how to speed launch times. Of course they sent a few emails and then things just dropped off.
Perhaps everyone should email Eisler and remind him that it's not an isolated problem. He stated that it only took a few seconds to load on their computers at Microsoft FWIW.
