A Microsoft file hosting and synchronization service.
Hi Gareth C_27
Welcome to Microsoft Community
Based on your description, don't worry, we can work together to get closer to the answer.
According to the category/OneDrive/For family you posted, we can tell that your problem is "PDF file created from Word document uploaded to OneDrive is not syncing correctly" Feel free to correct me if my understanding is wrong. I can understand that it is frustrated at times that something goes wrong, and the fact that it has not been resolved is troubling.
Before getting to the real cause of the problem, let's discuss the following scenarios:
- Whether any error code display when the PDF file upload fails, for example, an error code similar to 0x800? For a sample of the OneDrive error code, please refer to this statement, click here .
- Whether the problem only behave like this when uploading PDF files, does other files upload correctly or not.
- Whether this PDF file carry the file name with the special symbol " "*: < >? / \ | "If the file name has special symbols, it may be restricted from uploading to OneDrive. For details, please refer to this statement, click here .
The above three scenarios can help us narrow down the scope of the problem. After checking, we recommend you to follow the statement below to fix the sync speed problem step by step, and try to switch OneDrive to a different network to troubleshoot the elements of network provider.
If there are any updates, please feel free to come back to the community.
