💡 If this control isn’t available or it jumps back to the default position after restart, please contact your IT or system administrator.


Polls, Quiz or Q&A do not work in presentation mode. The slide stays white.


One of the reasons why this may be happening could be your network setting. Click “Show content”, copy-paste the text and send it to your IT Department to add an exception for Slido.


Text to send to your IT admin:


Slido for PowerPoint currently doesn’t support proxy authentication of any kind. The processes -- Powerpnt.exe, Slido.exe and CefSharp.exe need to be able to run and connect to the following domains in order for the Slido Add-in to function properly.






If you’re using some type of firewall or proxy server, you can make the above mentioned domains to be accessed by the Add-in processes. The rules or exceptions would need to be configured using the domain masks instead of entering specific IP addresses as we use dynamic IP addresses.



Sidebar isn’t loading and stays white (or shows an error)


One of the reasons why this may be happening could be your computer policy set by your system administrator. Click “Show content”, copy-paste the following text and send it to your IT admin to adjust the rules.


Text to send to your IT admin:


If you’re using Microsoft Intune to manage the devices, the Attack surface reduction policy is enabled which blocks any Microsoft Office applications from creating processes. Also, Windows Defender may be blocking some parts of the Slido Add-in, too.


You can adjust the Endpoint Security Policy to exclude Slido for PowerPoint installation path from ASR rules. Here are the steps:


  1. Open Microsoft Intune and go to Endpoint security

  2. In the Manage section, open Attack surface reduction

  3. Click Create Policy

  4. Use Platform: Windows 10 and Profile: Attack Surface Reduction rules

  5. Click Create

  6. Go through the wizard and configure the policy. Enter the path C:\Users\*\AppData\Local\Slido\Slido for Windows in the Exclude files and paths from attack surface reduction rules policy.

  7. Include installed subfolders too.
