Dear @Ian Hargreaves, Thank you for posting your question in the Microsoft Q&A forum. I understand that Word/Excel or OneDrive asks you to sign in again few times each week.
To better assistance, could you please confirm following information:
- Are you using a work/school account or a personal Microsoft account?
- Could you please share the screenshot of the issue? Please hide any personal information.
Do you have more than one Microsoft account signed in on this PC (Office/OneDrive/Teams)?
- Is your account added in Windows: Settings > Accounts > Access work or school?
- When did this start (for example: after an update or password/MFA change)?
In the meantime, I recommend some steps below:
1/ Update Windows and Microsoft 365, then restart the PC.
2/ In Word/Excel: File > Account > Sign out, close all Office apps > restart > then sign in again.
3/ Check the OneDrive cloud icon > Settings > Account and confirm you are signed in.
Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
I truly appreciate your patience and understanding. If you have any further questions or need further clarification, please feel free to reach out. I'm looking forward to hearing from you.
Thank you for your cooperation.
