On the Icons, each file has a briefcase on the corner, meaning its ownership belongs to the domain/work account, which is what it signed in, however it tried to read it as a personal account. When you go in to the task manager, move to details, right click and add the "enterprse context" detail menu you can see that the context is set to "personal". I know what the one drive icons mean. My issue is that it should belong to my azure domain, instead the context is listed as "personal" which is what is keeping me from being able to access the files correctly. Some open, and each time you open you must choose the program to open it, and often times it will say you dont have access. Which is patently false since the account has always been a work account.
FYI it seems like you're unaware of that bit in the details protion of task manager. Normally for enterprise context it should list "whatever the domain is" when dealing with azure AD joined accounts/computers. it will list "personal" or N/A for legacy domain joined accounts/computers
