Windows 10 & Office 365 Problem with two accounts

[nksdr]

Hi there,

I have this very annoying problem!!

I have windows 10 pro with the latest updates. I am also office 365 subscriber.
Everything works great.

The problem begins when I add a new exchange account in Microsoft Outlook (choosing of course that I will use this account only for this app).

Then sometimes... opening e.g. Word I see that the added account in Outlook is connected with Word (or excel or any other office app!!!)

Any ideas to avoid this?
