Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello @Graeme Rutherford,
Thank you for reaching out to the Q&A forum!
I truly appreciate the effort you’ve already made to troubleshoot this issue on your own.
To help me support you more effectively, could you please provide a bit more information:
1.Could you please provide screenshots of the Macro Settings showing “Allow all macros” is enabled, and the file Properties page confirming the file is not blocked?
Note: I can help you blur or hide any personal information if needed.
2.When opening the file, do you see a yellow security warning bar or a red security risk bar?
3.Is the Excel file currently being opened from a local drive, or from a cloud‑synced location such as OneDrive or SharePoint?
4.You also mentioned that this Excel file is about allowance claim. Could you please confirm whether this claim is specifically related to ODSP?
5.I also noticed that the original tag on your post was set to “Microsoft System Center | Other.” Could you please confirm whether you are using a work or school account (managed by an organization), or a personal Microsoft account (such as Outlook.com or Hotmail)?
In the meantime, you may try opening the file from a Trusted Location by following these steps:
- You can open Excel => File => Options => Trust Center => Trust Center Settings => Trusted Locations.
- Then you select Add new location and choose a local folder, please check the box for "Subfolders in this location are also trusted".
- After that, move the .xlsm file into this folder, close Excel, and reopen the file.
For reference: Trusted Locations for Office files - Microsoft 365 Apps | Microsoft Learn
Additionally, if possible, you also try opening the same file on another device to see whether the behavior is the same.
I will wait for the screenshot from you so that I can research the issue further and test in my environment.
Please understand that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to identify the root cause and find a solution.
Looking forward to hearing from you.
