I have always find surprising that (a) some Microsoft stuff does not work well (b) Microsoft, the vendor, is not asked to solve the problem and (c) you, that are not a Microsoft employee, are asked by your workmates to fix it!
Since I can say 'no', I say 'no' to such requirements with questions like "Look at me: am I Microsoft?", "Do I look like Bill Gates?" or "Why don't you ask Microsoft to fix it?" After all, if I have a problem with my Toyota car, I will not demand, say, Peugeot-Citröen to fix it.
But, holy crap, IT is different: you are expected to fix Microsoft's sh*t, no matter you have never been given training in Microsoft technologies.
Saying "no" perhaps will no contribute to make you me a popular guy, but in return you save a lot of time, that you can use on productive tasks, and avoid lots of headaches.
