Syncing, Sharing, and Recovering Your Files

OneDrive is your personal cloud storage in Microsoft 365. Files you put there are stored in the cloud, synced to the devices you sign in on, backed up automatically, and available from a web browser anywhere. This article covers what you need to know to use it day to day.

OneDrive vs. SharePoint and Teams

Choosing the right location matters more than any other habit in this article.

• OneDrive is for your work: drafts, personal notes, documents only you need. If you leave the organization, this content goes away with your account unless someone retains it.
• SharePoint or a Teams site is for team work: anything a colleague might need to find without asking you. Content there survives staff changes and is owned by the team.

A useful rule: if you would have to share the file with more than one person, start it in Teams or SharePoint instead of OneDrive.

Getting to your files

In a browser

1. Go to https://www.office.com and sign in with your work account.
2. Select OneDrive from the app launcher (the grid icon in the top left).

The browser view always shows the authoritative copy of your files. If something looks wrong on your PC, check here first.

On a Windows PC

OneDrive is built into Windows. Once it is signed in, your files appear in File Explorer under a folder named for your organization, with a cloud icon beside it. A blue cloud icon in the system tray (near the clock) shows sync status.

On a Mac

Install the OneDrive app from the App Store if it is not present, sign in with your work account, and your files appear in Finder under OneDrive.

On a phone or tablet

Install the OneDrive mobile app and sign in with your work account. Your organization may require the device to meet security policies before access is granted.

Understanding sync status icons

In File Explorer or Finder, a small badge on each file tells you where it lives.

• Blue cloud outline: the file is online only. It takes no disk space and downloads when you open it. You need an internet connection.
• Green check on white: the file is downloaded and available offline. It will be removed again if disk space runs low.
• White check on solid green: the file is pinned to Always keep on this device and will never be removed automatically.
• Blue circular arrows: syncing right now.
• Red circle with a white cross: sync error. Open the OneDrive tray icon to see the reason.
• People icon: the file or folder is shared with someone.

This behavior is called Files On-Demand. It lets a large OneDrive fit on a small laptop drive.

Making files available offline

Before traveling or working somewhere without connectivity, right-click the file or folder and choose Always keep on this device. To free up space later, right-click and choose Free up space. The file stays in the cloud either way.

Sharing a file or folder

Share links instead of email attachments. A link always points at the current version, and you can revoke it later.

1. Right-click the file in File Explorer, or select it in the browser, and choose Share.
2. Select the permission setting (usually shown as Anyone, People in [your organization], or Specific people).
3. Choose Specific people unless you have a reason not to. This requires each recipient to sign in.
4. Decide whether recipients can edit. Clear the Allow editing option if they only need to read.
5. Enter names or email addresses, then send the invitation or copy the link.

Some sharing options may be disabled by your organization's policy. If an option is grayed out, that is intentional, not a fault.

Seeing and removing access

In the browser, select the file and choose Manage access. From there you can change someone from edit to view, or remove them entirely. Review this whenever a project finishes or a contractor leaves.

Working on files at the same time

Word, Excel, and PowerPoint files stored in OneDrive support co-authoring. Multiple people can edit at once and see each other's cursors. For this to work reliably:

• Use modern formats (.docx, .xlsx, .pptx). Older .doc and .xls files do not co-author.
• Enable AutoSave (the toggle in the top left of the Office app). It is on by default for files in OneDrive.
• Avoid keeping a second copy on your desktop. That is how conflicting versions appear.

Recovering files

Previous versions

Right-click the file in File Explorer or the browser and choose Version history. You can preview an older version, restore it, or download it as a separate copy. This is the fastest fix for an accidental overwrite.

Deleted files

Open OneDrive in the browser and select Recycle bin in the left pane. Deleted items normally remain there for a limited retention period set by your organization, then move to a second-stage recycle bin before being purged permanently. Select the item and choose Restore.

Large-scale problems

If many files were encrypted, corrupted, or mass-deleted, use Settings > Restore your OneDrive in the browser to roll your whole OneDrive back to a point in time within the last 30 days. Contact the ServerNova service desk before doing this if you are unsure, especially if ransomware is suspected.

Known Folder Move

Your organization may redirect your Desktop, Documents, and Pictures folders into OneDrive. If so, saving to Documents as you always have now backs the file up automatically and makes it available on your other devices. You do not need to change your habits, and the folders keep their familiar names and icons.

Common issues

Sync is stuck or shows a red X

Select the OneDrive tray icon to read the specific error. Most are caused by an unsupported file name, a file open in another program, or a full OneDrive.

A file name is rejected

These characters are not allowed anywhere in a name: " * : < > ? / \ |. Names also cannot start or end with a space, and leading ~$ is reserved.

A file appears twice with your computer name appended

That is a sync conflict copy. Two devices edited the file while offline. Open both, merge anything you need, and delete the duplicate.

You are out of space

Check your quota in the lower left of the OneDrive browser view. Empty the recycle bin, which still counts against your storage, before requesting more space.

OneDrive keeps asking you to sign in

Sign out of OneDrive from the tray icon settings, then sign back in with your full work email address. If it repeats, open a ticket.

Good practices

• Keep shared work in Teams or SharePoint, not in your personal OneDrive.
• Prefer Specific people links and remove access when a project ends.
• Let AutoSave do its job instead of keeping dated copies like report-v7-final.docx. Use version history instead.
• Do not store regulated or highly sensitive data in OneDrive unless your organization has approved it for that purpose.
• Check the sync icon before shutting a laptop down after heavy editing, so changes finish uploading.

Getting help

If sync errors persist, files are missing after the recycle bin retention period, or you need a storage increase, contact the ServerNova service desk. Include the file or folder path, the exact error text from the OneDrive tray icon, and the device you are using.
