Microsoft Offer Getting held up in Audit

It's been a week and a couple days since a verbal offer and negotiation call with Microsoft. A week or so since a business approved verbal offer, which I would like to accept. In the last week, the recruiter and I have talked every couple days, always with the same outcome... "It's in audit, the hiring manager is chomping at the bit, they are calling me even more than you are, I'd love to promise you a timeline, but I don't want to promise something I cant deliver." How long do internal hurdles take to get to the offer in the Action Center? Based on what I know of Microsoft, this is "in band" but "above target" offer. Or does that not even matter, and it's just "corporate stuff"? Most of the past companies I have worked with, the delay is in getting to business approval, the HR stuff is set criteria that gets checked along the way in parallel process.
