O365 PRO PLUS Credentials

I have actually seen this behaviour, even just yesterday with a client who has a license under his local college.  But this also happens elsewhere outside the ProPlus/Academic licensing world.  

First, I'll say, I'm not the authority on why exactly this occurs, but, Microsoft has been ramping up their account security requirements and I would not be surprised to learn that this is a simple process of ensuring passwords are known.  Bottom line: Cached passwords are a convenience but every individual is required and expected to know their credentials.  simply put if they're too lazy to keep track, sucks to be them.  Of course this is a pain in a helpdesk environment where 30% of inbounc calls are password issues, so that's an organizational downside and is of course one of the reasons the concept of cached creds even exists.  🙂 

What I do not know, is whether this occurs due to connection issues with the licensing server, because nearly every computer I maintain, if I happen to check the Application event logs, there are always errors connecting to the Office 365 licensing servers.  This is universal, I have dozens of clients so it's not at all isolated, but perhaps this contributes to prompting for creds.  

I'm sure an Office 365 MVP can answer better.  Ever since this MS Tech Communities thing came up in place of the TechNet Forums I used to use, ti's hard to get qualified answers (sometimes, often there are great answers).
