[If Microsoft Lists stopped](https://todayfixtech.com/fix-microsoft-365-login-issues/) syncing with OneDrive/SharePoint, the cause is usually either the local OneDrive sync client/device or a server-side problem (permissions, SharePoint backend, or a Microsoft service incident). Start by confirming whether the issue is local or backend, try non-destructive fixes (reload, sign out/in, restart clients, use another browser), then progress to re-linking or recreating the sync only if needed.

## Is this the sync problem I think it is (what symptoms to check first)

```text
Missing rows in synced folder
Stale data after edits
Sync errors shown in OneDrive client (red X, paused)
Specific sync error codes or messages (exact message varies)
```

Symptom

When this appears: usually immediately after you edit a list item or file and the change doesn't show on another device, [or when the OneDrive](https://todayfixtech.com/fix-onedrive-slow-performance/) client shows an error on the synced library.

1. Open the list in the SharePoint/Lists web UI and confirm whether the change is present there.
2. Check the OneDrive sync client on the machine showing the issue for red icons or explicit error messages.
3. Try the same action in a different client: another browser, the SharePoint web view, and mobile.
4. Test with another user who has the same list permissions, or sign in with your account on a different device.

If the list shows the change in the web UI but the desktop synced folder does not, the problem is likely the OneDrive sync client or the device. If the web UI is missing data too, the issue is server-side: list/library permissions, list content/structure, or a backend outage.

## Could this be my device, my account, or Microsoft's service? (how to narrow scope fast)

Before you start:

- Applies to: Microsoft Lists backed by SharePoint Online or OneDrive for Business synced libraries.
- Privileges needed: regular user sign-in for initial checks; tenant admin for Microsoft 365 service health and SharePoint ULS logs.
- Restart or backup: no restart or backup required for the initial checks.
1. Try another browser or an incognito/private window to rule out browser cache or extensions.

```text
Browser -> New Incognito/Private Window
```

Settings path

1. Test from another device (phone or another PC) using the same account. If the issue follows the account, suspect server or permissions.
2. Tenant admins: check Microsoft 365 Service health in the Microsoft 365 admin center: Health > Service health.
3. Confirm other users see the same behavior. Have a coworker with the same access perform the same edit.
4. Verify your account permissions on the list/library.

```text
SharePoint site -> Site contents -> List -> Settings -> Permissions for this list
```

Settings path

1. On the device, inspect the OneDrive client: OneDrive menu -> Help & Settings -> View online and View sync problems.

If a Microsoft service incident is shown, follow the incident guidance. If other users are fine and the web UI is correct, focus on the device and OneDrive client.

## Quick fixes to try first (safe, non-destructive)

These are zero-risk, reversible steps — try them in order.

1. Force reload the list or page.

```text
Browser -> Reload/Refresh (or Ctrl+F5)
```

Settings path

Expected result: web UI reflects latest data. If not, proceed.

1. Sign out and sign back in to SharePoint/OneDrive and the browser.

```text
OneDrive client -> Help & Settings -> Sign out
Browser -> Sign out of Microsoft 365 -> Sign in
```

Settings path

Expected result: credentials refresh and tokens renewed. If errors persist, continue.

1. Restart the OneDrive sync client on the device.

```cmd
taskkill /f /im OneDrive.exe
start "" "%localappdata%\Microsoft\OneDrive\OneDrive.exe"
```

Command Prompt

Expected result: client reconnects and resumes sync. If the client shows the same error, try step 4.

1. Clear browser cache or use a supported browser (Edge or Chrome). Temporarily disable browser extensions that alter requests (ad blockers, privacy extensions).

```text
Browser -> Settings -> Clear browsing data (cached images and files)
```

Settings path

Expected result: web UI behavior normalizes. If still failing, continue.

1. Update clients: ensure OneDrive and your browser are on the latest version.

```text
OneDrive client -> Help & Settings -> Settings -> About -> Version
Browser -> Settings -> About <browser>
```

Settings path

Expected result: fixes that depend on client updates take effect after restart. If these quick steps don't resolve the issue, move to deeper fixes.

## Deeper fixes when quick steps don't work (permission, cache, re-linking, recreate sync)

These steps are more invasive. Follow the order: permissions and non-destructive client resets first, then re-link or recreate sync if necessary.

1. Check and fix list/library permissions (non-destructive).

```text
SharePoint site -> Site contents -> List -> Settings -> Permissions for this list
```

Settings path

Expected result: the affected user has at least Edit permissions. If permission inheritance is broken, re-grant explicit permissions or re-inherit. If permission changes don't fix sync, proceed.

1. Remove and re-add the sync connection in OneDrive (re-link). This is non-destructive to source data but will re-download the synced copy locally.

```text
SharePoint list -> Sync (in the toolbar) -> follow OneDrive prompt to stop sync -> then Sync again
```

Settings path

Stopping sync does not delete items in SharePoint but will remove the local sync folder reference. Back up any local unsynced changes first.

Expected result: a fresh sync folder is created and files/list items start syncing. If the client still errors, continue.

1. Clear OneDrive cache (reset the client, non-destructive but causes a full re-sync).

```cmd
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset
```

Command Prompt

Expected result: OneDrive resets and performs a full resync. If onedrive.exe /reset does not restart automatically, start it manually.

```cmd
start "" "%localappdata%\Microsoft\OneDrive\OneDrive.exe"
```

Command Prompt

1. Inspect list structure and content for problematic items: unsupported column types, complex lookup chains, calculated fields, very large attachments, or very large lists (rows). Move or temporarily remove the column or large attachments to test.

Removing columns or deleting items is destructive; export or back up the list first.

```text
List -> Export to Excel / Quick edit -> copy to backup
```

Settings path

Expected result: after removing or moving problematic content, sync resumes. If structural fixes are impractical, proceed.

1. Re-create the list or library as a last resort. Export data, create a new list with supported column types, import data, then sync the new list.

```text
List -> Export to Excel -> Site contents -> New -> List -> Import spreadsheet or Create and then import
```

Settings path

Expected result: new list syncs normally. Only do this when other fixes fail and you have a verified backup.

## How to verify the problem is solved and what to capture if you escalate

Verify bi-directional sync:

1. Make a small test edit in the web UI (change a field value) and confirm it appears in the synced folder on the desktop within a few minutes.
2. Make a change in the local synced folder (create or edit a file) and confirm it appears in the web UI and on another device.

Expected output:

```text
Edits propagate both ways within expected sync time; OneDrive client shows "Up to date."
```

Expected output

If not resolved, collect these diagnostics before escalating:

- A screenshot of the OneDrive client showing the error, including timestamp.
- The OneDrive sync client diagnostic report: OneDrive -> Help & Settings -> Settings -> About -> Open your OneDrive folder -> Sync problems, or use the diagnostic log export if available.
- Browser console output when reproducing the error: open DevTools (F12) -> Console -> reproduce and save the output.
- Exact error text and error code as displayed, with timestamps and the user account that experienced it.

```text
Example error text to capture:
"Error: Sync failed - [error code] - [exact message]"
```

Text

- For tenant admin escalation: SharePoint ULS correlation ID from the error (if shown), the time window, the site URL, and the affected list name.

When opening a ticket provide: tenant ID, affected user accounts, timestamps, screenshots, OneDrive client version, browser and OS versions, and the steps to reproduce the issue.

## Common root causes and prevention (why this keeps happening and what to change)

Common root causes and how to address them:

- Permissions and inheritance breaks: use groups instead of per-user grants, and audit permission changes regularly.
- Conditional Access or MFA blocking background sync: create an exception policy for OneDrive/SharePoint sync or require device compliance instead of interactive MFA for trusted devices.
- Large attachments, oversized rows, or list size limits: move large attachments into SharePoint document libraries and link them from the list; archive old rows and use indexed columns for performance.
- Unsupported or complex column types (lookup chains, calculated fields): simplify the list schema where possible and test schema changes in a staging list.
- Outdated or buggy OneDrive sync client: enforce automatic client updates and monitor client versions in the tenant.
- Network interruptions or proxy/TLS inspection interfering with authentication: ensure required endpoints are allowed and TLS inspection devices aren't breaking tokens.

Prevention and monitoring:

- Schedule periodic audits of large lists, permission anomalies, and OneDrive client versions.
- Apply retention and archival policies to keep list sizes manageable.
- Keep a documented re-link/reset procedure and require backups before destructive steps.
- Validate conditional access test policies that permit OneDrive background sync for compliant devices before rolling them out.

## Conclusion

If non-destructive checks and client resets fix the problem, monitor the list for a day and note client versions and patterns. If the issue persists after permission and cache resets, collect the diagnostics described above and escalate to your tenant admin or Microsoft support with timestamps and exact error strings.

## Frequently Asked Questions

### Will stopping and restarting OneDrive delete data from SharePoint?

No. Stopping sync or resetting the OneDrive client removes the local sync state and may remove the local synced folder reference, but it does not delete data stored in SharePoint. Back up any unsynced local changes before stopping sync.

### How long should I wait after a reset for changes to appear?

After a client reset or re-link, a full re-sync can take minutes to hours depending on list size and network speed. Small lists and test edits should show up within a few minutes.

### What list column types commonly cause sync issues?

Complex lookup chains, multi-lookup columns, heavily used calculated fields, or unsupported third-party column types can cause problems. Simplifying schema or using document libraries for large files helps.
