This project completed in July, 2019. This is an archive for informational purposes.

The majority of data owned by U-M users is in OneDrive, including uploaded files, files created via Office Online tools, and files saved from downloaded Office products (Word, PowerPoint and Excel). If you currently store files in U-M Office 365, they are likely in OneDrive.  

Migration Path

ITS will migrate files and their share settings.

Updated July 12: A solution for syncing OneNote Notebooks for both Windows and macOS desktops is now available. See the OneNote section at the bottom of this page.

Updated July 9: A solution for syncing OneNote Notebooks on Windows machines is available. See the OneNote section at the bottom of this page. Mac users should contact the ITS Service Center for assistance.

Updated July 8: Over 99% of OneDrive users have had their data migrated. Some users are reporting issues with accessing and syncing their OneNote Notebooks, which the project team is currently troubleshooting.

Updated July 2: Approx. 84% of OneDrive users have had their data migrated.

Updated June 27:

  • We anticipate that most, but not all, migrated content will be accessible by July 1. This is especially true for users who had large amounts of data stored in OneDrive.
  • Microsoft Office applications and files installed on a local device will not be affected during the migration period. Consider downloading and syncing any documents that you must have access to on July 1.

What will migrate?

  • All documents stored in OneDrive
    • Includes images, documents, PDFs, spreadsheets, presentations, videos, audio files, etc. 
    • Includes OneNote data, but requires additional steps, listed below.
    • Items in the online OneDrive Recycle Bin will NOT be migrated.
  • Folder structure
  • All file share settings

Impacts & Actions Needed After the Migration

File Sharing

Links to online files (documents, spreadsheets, and presentations) will be available in the new platform to anyone who currently has access, however the URL for those files will change. This means that if the person the document was shared with clicks a link in an old email or bookmarked the document, that link will no longer exist. (Note that shares outside of the university were not enabled prior to the migration, so shares will only be with other U-M accounts.)

  • Links to documents on websites will need to be updated, including favorites/bookmarks.
  • If you have shared documents with others, you will need to re-share these documents after migration.
  • Share recipients should also update any bookmarks. (Share recipients can find shared documents in the online version of OneDrive for Business in their Shared folder.)

Desktop Sync

Devices using OneDrive Sync will need to be restarted after migration so they connect to the new platform. All files will re-sync as their modification dates will have changed. Note: The files themselves will not be modified by the migration. However, because the last modified date for the files will be the date they were migrated, the sync tool will recognize that new date and sync the “new” file to your computer. 

Mobile Applications

You will need to sign out and sign in again for any mobile application you’re using (such as Word, OneDrive, and Teams). 


(These steps apply to Windows, Mac, and mobile clients.) While the ITS migration tool will move OneNote notebooks and notes, it cannot move the synchronization settings. After the migration, you will need to sign out of any OneNote client and reauthenticate to force a re-sync of your Notebooks. If, after signing in again you don’t see your Notebooks synced to the client, manually open each Notebook and OneNote will sync notes in that Notebook.

If you are having difficulty syncing your Notebooks, please follow these steps.
