Hello @Concierge Lead,
Good day! Thank you for posting your valuable question on Microsoft Q&A forum.
Before providing the accurate solution, can you confirm some additional information:
- Is your account a personal account (e.g., Hotmail, Gmail, Yahoo, Outlook.com) or a work/school account (e.g., one that uses your organization’s domain name)?
- If it’s a work/school account, are you a Microsoft 365 administrator for your organization?
- Which applications are you unable to sign into, and which ones are you still able to access successfully?
- Do you still have access to your Authenticator app on your device?
- Can you provide the exact error message or error code you’re seeing?
This information is important to understand your situation better and I can provide you with the suitable next steps.
If you have a work/school account and this is a time-sensitive issue that needs immediate assistance, I recommend contacting your organization's IT administrator (who is likely your system administrator or can direct you to them).
This issue is likely related to how your account is managed within your organization, and your IT admin will have the appropriate tools and permissions to help resolve it promptly.
If you have a personal account, you can request a support ticket to Microsoft Technical support team:
- Go to https://support.microsoft.com/contactus
- Choose Microsoft 365 > Get Home Support
- Enter Office or your issue in general in the box below "We're here for you" then click "Get Help
- Scroll down and click on Contact Support then log in to your personal Microsoft account. If the account cannot be logged in, you can use another account or create a new account to execute
- Select "Microsoft 365 and Office" in Products & Services, select "Technical Support" as a category, and click Confirm
- Select "Chat in a web browser and support specialist" to enter the chat window
You can also provide the information I requested, and I will be happy to assist further! Thank you for your kindness and understanding!
