Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi BridgetMcCabe,
I go through the post carefully, based on the description, it seems that your get upload Failed/Blocked error in Office, however the files are uploaded to cloud normally. Usually Office will verify users’ account when uploading files to OneDrive/SharePoint and the issue may happen if user have many accounts signed in Office. Here are some suggestions:
- Clear Office license files with License removal tool, then sign in back to Office. This can help solve account conflict related issue. you may download the tool from the link: **** How to remove Office license files on a Mac - Office Support
- Reset OneDrive on the Macs and check the result. On how to reset, please check the link: Reset OneDrive - Office Support (microsoft.com)
Best Regards,
Clark
