SharePoint Online: Change Idle Session Timeout Settings

Task: Set idle session timeout value for SharePoint Online.

How to Set SharePoint Online Idle Session Timeout?

Did you know that there is a session timeout for SharePoint Online? Well, Idle session timeout in SharePoint Online is a security mechanism that warns and sign-outs the user after a period of inactivity. By default, idle session timeout settings are disabled in SharePoint Online. In this post, we will walk through how to modify your session timeout settings for SharePoint Online. We’ll also provide some tips on how to extend your session timeout beyond the default setting.

To enable idle session timeout in SharePoint Online, follow these steps:

• Login to SharePoint Online Admin Center
• Click on “Policies” >> Access Control >> Idle session Sign-out
• Turn-On the Idle session timeout and set other configuration parameters accordingly.

  

This ensures that your users’ sessions are terminated after a set amount of time of inactivity, which can help to improve security and performance. The idle timeout settings apply only to web browsers – It doesn’t affect any clients such as the OneDrive Sync client – they stay logged in as usual.

SharePoint Online: Configure Idle Session Timeout using PowerShell

To set default session timeout values, use the PowerShell cmdlet: Set-SPOBrowserIdleSignOut, Open SharePoint Online Management Shell, and run this PowerShell script to change SharePoint Online session timeout:

#Set Config parameters
$AdminSiteURL = "https://crescent-admin.sharepoint.com/"

#Connect to SharePoint Online Tenant Admin
Connect-SPOService -URL $AdminSiteURL -Credential (Get-Credential)

#Get Current Idle session Timeout values
Get-SPOBrowserIdleSignOut

#Change Session Timeout Value
Set-SPOBrowserIdleSignOut -Enabled $true -WarnAfter (New-TimeSpan -Minutes 30) -SignOutAfter (New-TimeSpan -Minutes 60)

#Verify the settings
Get-SPOBrowserIdleSignOut

This setting dictates how long a user’s session is allowed to remain idle before it is automatically terminated. By default, this value is set to 0 minutes, meaning that the user’s session will not expire until they explicitly log out. However, by adjusting this setting, you can control how much time a user has before their inactive session is terminated.

So, after executing the above script, SharePoint Online gives a warning after 30 Minutes. If the users press the continue button, they can continue working until the next time they leave the browser window idle for the warning period configured.

And if there is no activity from the end-user, then SharePoint Online automatically redirects to the sign-out page.
