I have issue signing in to my microsoft office account.

Hi @Jianli Liu

Welcome to Q&A Community! 

Thank you for reaching out. I understand you're currently unable to sign in to your Microsoft Office account. 

To better assist you, could you please provide the following details: 

1. Are you signed in with a personal account (e.g., @hotmail.com, @outlook.com), an education account (e.g., @school.edu), or a work account (e.g., @yourcompany.com)? 
2. Are you receiving any specific error messages when attempting to sign in? (e.g., “We couldn’t sign you in,” “Incorrect password,” etc.) 
3. Which platform are you using to sign in? (e.g., Office desktop apps, web browser via www.office.com 
4. Have you recently changed your password or made any updates to your account? 
5. Have you tried signing in from a different device or network to rule out local connectivity issues? 

In the meantime, here are a few steps you can try: 

• Clear your browser cache and cookies, then try signing in again via www.office.com 
• Use an incognito/private browser window to avoid cached login sessions. 
• Check your internet connection and ensure it’s stable. 
• Try signing in from another device (e.g., mobile phone or another computer). 

Please reply with the requested details so I can provide more targeted assistance. If this is related to a known outage, I’ll also keep you updated on the latest status. 

Please feel free to correct me if there are any misunderstandings. Kindly let me know if there are any further concerns or if you need more assistance. I am happy to help!
