When opening an Excel document, I am getting the following error displayed at the top of the Excel spreadsheet.
"Upload Blocked We ran into a problem with this file and can't save any new changes. Please save a copy to avoid losing your work."
This could be caused by one of the following. See below for the solution for each of these.
- Two different accounts are used to sync files on two different tenants
- In the past, spreadsheets have not uploaded correctly via OneDrive
Two different accounts are used to sync files on two different tenants
Refer to the Microsoft help article https://docs.microsoft.com/en-us/sharepoint/troubleshoot/sync/upload-blocked-error-in-o365.
In the past, spreadsheets have not uploaded correctly via OneDrive
This can be caused where, in the past, spreadsheets have not uploaded correctly via OneDrive. Having a file that has not uploaded correctly can cause issues with other documents.
This is a Microsoft error. Refer to the Microsoft article https://support.microsoft.com/en-us/topic/files-needing-attention-faq-5c944ab8-1dd5-44f3-9dc6-9cd35846f8ab
With OneDrive, the upload can be an issue with macro enabled spreadsheets, especially where the spreadsheets are large or includes references to other spreadsheets or where it uses pivot tables.
The following is the recommended best practice to avoid this issue and needs to be performed on each computer that is having the issue:
- Ensure your computer is correctly configured to work offline with FYI including OneDrive. Refer to Configuring your OneDrive for use with FYI.
- In Excel, check if there are any Files Needing Attention. Files that have failed to upload need to be removed.
- Open Excel.
- In File - Open, check for any files in that application that are showing as Files Needing Attention.
Refer to the Microsoft article Files Needing Attention FAQ.
- From Files Needing Attention, you can open the file and re-save, or, you can discard the changes completely.
- Try editing a document again.
Note: Office Upload Center has now been depreciated and replaced with the Files Needing Attention function in the relevant Office application.
