Fix Excel File Opens Slowly in SharePoint for One User
Question details
An Excel workbook hosted on SharePoint Online is opening very slowly for a single user account, even across different devices, while other users experience normal performance.
- Product
- Microsoft Excel, SharePoint Online
- Device & OS
- not provided
- Scenario
- Opening a shared Excel workbook through SharePoint Online.
- Observed behavior
- The Excel file takes an abnormally long time to load, but the issue is isolated to one specific user account and persists regardless of the computer or browser being used.
Verify that your browser and operating system are fully updated, and try logging into your account on a colleague's computer to confirm the slow performance strictly follows your user profile.
Request Microsoft 365 Support via IT Administrator
Since the performance issue is isolated to a single account across multiple devices, Microsoft Support needs to investigate backend account-specific logs.
When a SharePoint performance issue follows a specific user account regardless of the device used, it typically indicates a backend profile synchronization problem or a permission glitch within Microsoft 365. Local troubleshooting steps, such as clearing the browser cache or reinstalling software, will generally not resolve account-level server issues.
Note down the exact URL of the affected Excel file, the specific user account experiencing the issue, and confirm that the problem persists on different computers.
Reach out to your internal IT team or Microsoft 365 administrator, explaining that the issue affects only your account and not the file itself.
Request your administrator to navigate to the Microsoft 365 admin center and submit a formal support request to Microsoft to collect and analyze account-specific backend logs.

Frequently Asked Questions
Why does an Excel file open slowly for only one user?
This usually happens due to account-specific backend synchronization issues, corrupted user profile metadata in SharePoint, or unique complex permission structures assigned specifically to that user account.
Can clearing my browser cache fix SharePoint Excel online issues?
If the issue only happens on a single device, clearing the cache might help. However, if the slow performance follows your account across different computers, it is a server-side account issue rather than a local browser problem.
Does file size affect SharePoint Excel opening times?
Yes, larger files with complex formulas, macros, or extensive data connections take longer to load in Excel Online. However, if colleagues can open the same large file quickly, the file size is not the root cause of your specific account issue.
