How to Fix Microsoft 365 Sign-In Problems and Recover Missing OneNote Notes
Question details
The user is unable to sign in to Microsoft 365 due to installation conflicts and needs to recover missing Quick Notes in OneNote.
- Product
- Microsoft 365 and OneNote
- Device & OS
- not provided
- Scenario
- Attempting to sign in to Microsoft 365 and retrieve OneNote Quick Notes after changing an account password or reinstalling Office applications.
- Observed behavior
- Sign-in fails because of a version conflict between Office 2019 and Microsoft 365, and previously saved notes are missing from the OneNote application.
Verify whether you are using a personal, work, or school Microsoft account, and ensure you have administrative privileges to uninstall software on your device.
Remove Conflicting Office Installations Using the Recovery Assistant
Use the Microsoft Support and Recovery Assistant to completely remove conflicting versions of Office (like Office 2019) that prevent Microsoft 365 from signing in properly.
Office 2019 and Microsoft 365 are entirely separate products with different licensing structures. Having residual files or concurrent installations of both can confuse the authentication service, resulting in sign-in errors.
Download the Microsoft Support and Recovery Assistant (SaRA) from the official Microsoft support website.
Run the application, select 'Office', and then choose 'I have Office installed, but I'm having trouble uninstalling it.'
Select the older or conflicting versions (such as Office 2019) from the list and follow the on-screen prompts to completely remove them.
Restart your computer, launch your newly installed Microsoft 365 application, and sign in using the correct personal or work account.
Locate and Recover Missing OneNote Notes
Check your synchronization status, correct the signed-in account, and review the notebook recycle bin to find your missing Quick Notes.

Frequently Asked Questions
Why does Microsoft 365 show a sign-in error when Office 2019 is installed?
Office 2019 is a one-time purchase, while Microsoft 365 is a subscription service. Having both installed on the same device causes conflicts in the background licensing services, which prevents the applications from accurately verifying your account credentials.
Where are my OneNote Quick Notes stored by default?
By default, Quick Notes are saved in a dedicated section of your primary default notebook (often named 'Personal' or '[Your Name]'s Notebook') synced to your OneDrive. You can change this location by navigating to File > Options > Save & Backup within OneNote.
Can I use a personal Microsoft account for Microsoft 365?
Yes, you can use a personal Microsoft account if you are subscribed to Microsoft 365 Personal or Family. If you try to log into a business or enterprise version of the software with a personal account, you will encounter a sign-in error.
