When you open a PowerPoint file or try to save a presentation, you may see the error message The server is not available. This error typically occurs because PowerPoint cannot communicate with a required system service or add-in component. The problem is often caused by a corrupted add-in, a blocked DCOM (Distributed Component Object Model) permission, or a conflict with your antivirus software. This article explains why the error happens and provides step-by-step fixes to resolve it in Windows 11 and Windows 10.
Key Takeaways: Fixing the Server Is Not Available Error in PowerPoint
- File > Options > Add-ins > Go (COM Add-ins): Disable third-party COM add-ins that block server communication.
- Component Services > DCOM Config > Microsoft PowerPoint: Restore default launch and activation permissions for the PowerPoint DCOM object.
- Windows Security > Virus & threat protection > Manage settings: Add PowerPoint and its parent folder to the antivirus exclusion list to prevent blocked file access.
Why PowerPoint Shows the Server Is Not Available Error
PowerPoint uses DCOM to communicate with system services and embedded objects such as Excel charts, Word documents, or media players. When the DCOM permissions for the PowerPoint application object are changed or corrupted, Windows blocks the communication and raises the server is not available error. This problem is not a network issue despite the wording. It is a local permission or add-in conflict.
The error can also appear if a COM add-in registered in PowerPoint crashes or fails to load. Add-ins such as PDF converters, screen capture tools, or third-party presentation enhancers often register themselves as COM servers. If the add-in server is unresponsive or missing, PowerPoint cannot start it and shows the error.
Common Triggers
Three scenarios most often trigger this error. First, a recent Office update may have reset DCOM permissions. Second, you installed a new add-in or updated an existing one. Third, your antivirus software blocked a file that PowerPoint needs to access during startup or save operations. Antivirus programs sometimes quarantine PowerPoint helper files, causing the server lookup to fail.
Steps to Fix the Server Is Not Available Error
Perform the following fixes in the order shown. Test PowerPoint after each step to confirm whether the error is resolved.
1. Disable All COM Add-Ins
- Open PowerPoint in Safe Mode
Press and hold the Ctrl key while double-clicking the PowerPoint icon. Click Yes in the confirmation dialog. If PowerPoint opens without the error, a third-party add-in is the cause. - Open Add-ins Manager
Go to File > Options > Add-ins. At the bottom of the window, next to Manage, select COM Add-ins from the drop-down list and click Go. - Disable All Add-ins
In the COM Add-ins dialog, clear every check box. Click OK and restart PowerPoint normally. If the error does not appear, enable add-ins one by one to identify the problematic one.
2. Restore Default DCOM Permissions for PowerPoint
- Open Component Services
Press Windows key + R, typedcomcnfg, and press Enter. In the Component Services window, expand Component Services > Computers > My Computer > DCOM Config. - Locate Microsoft PowerPoint DCOM Object
Scroll the list until you see Microsoft PowerPoint Presentation or Microsoft PowerPoint. Right-click it and select Properties. - Set Launch and Activation Permissions
In the Properties dialog, go to the Security tab. Under Launch and Activation Permissions, select Use Default. Click Apply and then OK. - Restart PowerPoint
Close all Office programs and reopen PowerPoint. If the error persists, restart Windows to apply the permission changes fully.
3. Repair Office Installation
- Open Programs and Features
Press Windows key + R, typeappwiz.cpl, and press Enter. Find Microsoft 365 or Microsoft Office in the list. - Run Quick Repair
Right-click the Office entry and select Change. In the window that opens, choose Quick Repair and click Repair. Follow the on-screen prompts. - Run Online Repair if Needed
If the Quick Repair does not resolve the error, run the Online Repair option from the same dialog. This process reinstalls Office components and fixes corrupted registry entries.
4. Add PowerPoint to Antivirus Exclusions
- Open Windows Security
Go to Start > Settings > Privacy & Security > Windows Security, or search for Windows Security in the Start menu. Click Virus & threat protection. - Manage Exclusions
Under Virus & threat protection settings, click Manage settings. Scroll to Exclusions and click Add or remove exclusions. - Add PowerPoint Executable
Click Add an exclusion, choose File, and browse toC:\Program Files\Microsoft Office\root\Office16\POWERPNT.EXE. Click Open to add it. Also add the folderC:\Program Files\Microsoft Office\root\Office16as a folder exclusion. - Restart PowerPoint
Close and reopen PowerPoint to test if the error is gone.
If PowerPoint Still Shows the Error After the Main Fix
PowerPoint Error Appears Only When Opening a Specific File
A corrupted embedded object inside the presentation can trigger the server error. Open the file in Safe Mode by holding Ctrl while launching PowerPoint. If the file opens, go to File > Info and click Check for Issues > Inspect Document. Remove any embedded objects or linked content. Then save the file under a new name.
PowerPoint Error Occurs After a Windows Update
Windows updates sometimes change DCOM security descriptors. Run the Microsoft Easy Fix tool for Office activation and permissions. Alternatively, run System File Checker. Open Command Prompt as administrator, type sfc /scannow, and press Enter. Restart after the scan completes.
PowerPoint Error Appears When Using a Specific Add-In
If the error only happens when a particular add-in is enabled, the add-in server is outdated or incompatible. Visit the add-in developer’s website and download the latest version. If no update exists, remove the add-in permanently. Go to File > Options > Add-ins, select the add-in, and click Remove.
PowerPoint Online vs Desktop: Server Error Behavior
| Item | PowerPoint Desktop | PowerPoint Online |
|---|---|---|
| Error occurrence | Local DCOM permission or add-in conflict | Browser or network connectivity issue |
| Main cause | Corrupted COM add-in or blocked DCOM object | Outdated browser cache or firewall block |
| Fix approach | Disable add-ins, repair Office, restore DCOM permissions | Clear browser cache, disable extensions, check firewall |
| Affected features | Embedded objects, linked content, save operations | Real-time co-authoring, embedded media playback |
PowerPoint Online uses a browser-based server model. The error in the online version is almost always a browser issue, not a DCOM problem. Clearing the browser cache or using a different browser resolves it. The desktop version requires the DCOM and add-in fixes described in this article.
After applying the steps above, PowerPoint should open and save presentations without the server error. If the problem returns, check for new add-ins installed recently or revert the most recent Windows update. As a final measure, use the Microsoft Support and Recovery Assistant tool to scan for Office configuration issues automatically.
