Fix Word Co-Author Presence Indicator Misshowing User as Offline

When you collaborate on a document in Word, the co-author presence indicator shows green dots for active users and red dots for offline users. Sometimes the indicator incorrectly shows a user as offline even though that person is actively editing the document. This problem usually happens because of a stale presence cache, a misconfigured Microsoft 365 connection, or a delay in the sync service. This article explains why the presence indicator fails and provides step-by-step fixes to restore accurate online status for all co-authors.

Why Word Shows a Co-Author as Offline When They Are Online

The presence indicator in Word relies on the Microsoft 365 presence service, which communicates with the Word collaboration engine. When a user opens a shared document stored on OneDrive or SharePoint, Word sends a presence heartbeat to the service every few seconds. If the heartbeat fails or the service does not update the status, the indicator shows the user as offline.

Several factors cause this mismatch:

Stale authentication token. Word uses a cached token to connect to Microsoft 365. If the token expires or becomes invalid, the presence service cannot verify the user status. The indicator then defaults to offline.

Outdated Word build. Older versions of Word contain bugs in the collaboration module that prevent the presence indicator from updating correctly. Microsoft releases monthly updates that fix these issues.

Network or proxy interference. The presence service uses WebSocket connections to push real-time updates. Firewalls or proxy servers that block WebSocket traffic break presence updates.

Document sync delay. When a co-author opens the document, OneDrive or SharePoint must sync the metadata before Word can display the presence. A slow sync can delay or prevent the indicator from showing the user as online.

Steps to Correct the Co-Author Presence Indicator

Method 1: Sign Out and Sign Back Into Microsoft 365

1. Open Word and go to File > Account
   In the left pane, click File, then click Account at the bottom of the menu. This screen shows your connected Microsoft 365 account.
2. Click Sign Out below your account name
   A confirmation dialog appears. Click Sign Out to disconnect Word from Microsoft 365.
3. Restart Word completely
   Close all Word windows. Open Word again. This clears the cached presence data from memory.
4. Click Sign In in the upper-right corner
   Enter your Microsoft 365 credentials. After sign-in, open the shared document. The presence indicator now shows the correct online status for all co-authors.

Method 2: Update Word to the Latest Build

1. Go to File > Account > Update Options
   Click File, click Account, then click Update Options on the right side of the Product Information section.
2. Select Update Now
   Word checks for available updates. If an update exists, Word downloads and installs it. You may need to restart Word after the update finishes.
3. Verify the update installed
   Go back to File > Account. Under Product Information, look for the version number. The latest stable version for the Current Channel is Version 2410 or later. If you use Semi-Annual Enterprise Channel, ensure the version is 2408 or later.
4. Open the shared document again
   After the update, the presence indicator should refresh correctly.

Method 3: Close and Reopen the Document

1. Save your work and close the document
   Press Ctrl+S, then close the document tab in Word.
2. Wait 30 seconds
   This gives the presence service time to clear the stale session for your user.
3. Reopen the document from the Recent list or from OneDrive
   Click File > Open > Recent and select the document. Alternatively, open OneDrive or SharePoint in your browser and click the document to open it in Word.
4. Check the presence indicator
   The indicator now shows the correct online status for each co-author.

Method 4: Clear the Microsoft 365 Credential Cache

1. Open the Windows Credential Manager
   Press Windows+R, type control /name Microsoft.CredentialManager, and press Enter.
2. Click Windows Credentials
   Under the Windows Credentials tab, scroll to the Generic Credentials section.
3. Remove all entries that start with MicrosoftOffice
   Click the arrow next to each entry to expand it, then click Remove. Confirm the removal. Do not remove credentials for other applications.
4. Restart Word
   Close and reopen Word. Sign in again when prompted. Open the shared document to verify the presence indicator.

If Word Still Shows a Co-Author as Offline

Co-Author Uses a Different Microsoft 365 Tenant

The presence service only works for users within the same Microsoft 365 tenant. If a co-author has a guest account or uses a different tenant, Word cannot retrieve their presence status. The indicator shows them as offline by design. Ask the co-author to confirm they are using the same tenant as the document owner.

Presence Indicator Does Not Update During a Video Call

When a co-author is in a Microsoft Teams call or a Skype for Business call, the presence service may prioritize the call status over the document editing status. The indicator shows the user as In a Call or Offline. This is expected behavior. The indicator reverts to online when the call ends.

Word Shows All Co-Authors as Offline

If every co-author appears offline, the problem is likely a network issue or a service outage. Check the Microsoft 365 Service Health dashboard at admin.microsoft.com under Health > Service Health. Look for any advisory under Microsoft 365 suite or Word. If the service is healthy, run the Microsoft Support and Recovery Assistant from the Microsoft 365 admin center to diagnose connectivity problems.

Word Desktop vs Word for the Web: Presence Indicator Differences

Item	Word Desktop (Microsoft 365)	Word for the Web
Presence update frequency	Every 5 seconds via WebSocket	Every 10 seconds via HTTP polling
Offline indicator cause	Stale token, outdated build, network proxy	Browser cache, expired session cookie
Fix for incorrect offline status	Sign out/in or update Word	Clear browser cache and cookies
Cross-tenant presence support	Not supported	Not supported
Presence during Teams call	Overridden by call status	Overridden by call status

After following the steps in this article, the co-author presence indicator in Word should show the correct online status for all editors. Signing out and back in is the fastest fix for most users. If the problem persists, update Word to the latest build and clear the credential cache. For users who work across multiple tenants, remember that presence only works within the same tenant. The presence indicator in Word for the Web can be fixed by clearing the browser cache, but the desktop version offers more reliable real-time updates.
