Dear Sadiya Khan,
Good day!! Thank you for posting in Microsoft Community. We are happy to help you.
Per your description, it seems like you have 3 questions. I'd like to help you. Let's address each of your concerns.
- Regarding the issue about you are unable to access specific folders under your organization account, may I know if you receive any error message when you access them? Are those folders stored in SharePoint document library? Could you please provide some screenshots? it would be very helpful to let me know the exact scenario.
- Regarding the Microsoft Authenticator app issue, we have a specific channel handling such issue, to make sure you get the professional support, I sincerely recommend you post your concern to Microsoft Q&A Community with Authenticator tag: Microsoft Authenticator - Microsoft Q&A
members and engineers over there are proficient in the knowledge of Authenticator app queries. They will focus on the specific situation on your side and provide specific suggestions for you.
- About removing accounts associated with the Same Email ID, does it mean that when you sign in your email id, it says it looks like the email is used with more than one account and it asks you which account do you want to use?
If yes, you may try the suggestions from this Microsoft article Which account do you want to use? - Microsoft Support
However, if my understanding of the third question is not right, feel free to post back and point it out, I will continue helping you.
Thanks for your time and cooperation! Hope you have a nice day!!
Best Regards,
Tina
