Windows 10: Upgraded Office 365 Personal to Family, other shared accounts are having problems

All shared accounts when opening Office gets a prompt of "Counterfeit Product". When I checked the current license on all shared accounts it's liked to a "Microsoft Office Professional 2016" and when I change it to Office 365, it doesn't do anything.My own Office 365 doesn't have issues, however when I sign-in to their Off.. I too, get a "Counterfeit Product" prompt and my license in their PCs and Laptops is linked to a "Microsoft Office Professional 2016" and can't change it to Office 365.I've uninstalled and reinstalled the application, I've signed-out then in, tried "Online Fix" through

Office 365 Outlook email accounts

The reason I am asking these questions are that two individuals are buying two new laptops and would like to share one Microsoft Office 365 Personal.
A has a subscription to Microsoft Office 365 Personal already and wants to share the same account with B.
I have installed Microsoft Office 365 Personal in a second pc B and when launching Outlook all my email accounts from A were loaded. So, I cannot figure out how to install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded.
This raises more questions for me.

1. So this
   • User A installs and activates O365 on User B's laptop
   • User B adds his / her email accounts to Outlook
   would not apply to Microsoft Office 365 Personal as it breaches the licence agreement?
2. Am I correct?
3. If it does apply how can I install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded, and I can only add B email account on the second pc?
4. Would B be able to access A OneDrive?
5. Or would B have a separate 1TB free space in One drive, or only the free 5GB or none at all?
6. And most importantly is this even legal or in breach of contract as Microsoft Office 365 Personal is for one user only?

 

Office 365 Outlook email accounts

O365 Personal cannot be shared. It can be installed on unlimited number of devices, but it must be activated with the same subscriber Microsoft account on each device.

Extract from Office 365 subscriptions - On how many devices can Office be installed:

However, the activation Microsoft account email does not have to be added to Outlook. A fully valid and functional example:

• User A subscribes to O365 Personal
• User A installs and activates O365 on his / her laptop
• User A adds his / her email accounts to Outlook
• User A installs and activates O365 on User B's laptop
• User B adds his / her email accounts to Outlook

The point is, that the O365 Personal subscriber email is required to activate Office on each device, but it don't have to be added to Outlook. In above example, both User A and User B add only their own email accounts to Outlook, and cannot see each other's accounts and emails.

Exactly.

 

Windows account cant access Office 365 Family license

My husband recently renewed his Office 365 and shared the license with me (as he had done previously). Since this renewal, i am unable to use the Office license if i log into windows under the same MS account as i use for Office 365.

• my MS account shows that the license is shared with me.
• if i log into windows under another (local) account, i can use the Office 365 shared license (I log into office 365 using the MS account)
• if i log into windows under the MS account, then log into Office 365 under that same MS account, it says i am not licensed to use Office 365.

After a 3 hour chat session with MS, it was concluded that i will need to log into windows under a different account if i want to use the MS Office license. During that 3-hour session (and before) we uninstalled/reinstalled office, and deleted numerous license
keys, to no avail. The tech decided that my windows account must be corrupted, and since he was an Office tech (not a Windows tech), he didnt know how that could be fixed, other than to use separate accounts for Windows and Office.

I can live with having 2 different accounts (1 for windows and 1 for office) but this seems like a dumb solution, especially when it used to work fine until this recent renewal.

Any insight welcome.
