When it comes to the corporate environment, everyone can agree that a good collaborative tool can mean the difference between projects getting done on time, and money being wasted.
That is why many companies use such tools, and one very good example is Microsoft Teams.

How do I fix the MS Teams’ third-party cookies error?
1. Use a GPO that enable s third-party cookies
Since third-party cookies are usually restricted at a corporate scale via Group Policies, the only obvious choice if you really want Microsoft Teams as your collaborative tool is to simply ask the IT administrators to enable a GPO that allows for cookies to be stored.
2. Manually enable third-party cookies on your browser
If your company does not have a GPO that forbids the saving of third-party cookies, then all you need to do is manually enable them on the browser you are using to access the Microsoft Teams web client.
Since this process varies greatly depending on what browser you are using, then you should check up on this in-depth article for steps on how to enable cookies on all of the major browsers.
3. Add MS Teams’ website in the Local Intranet zone
- Open Internet Explorer
- Click on Settings
- Go to Internet Options
- Select Security tab Local Intranet Zone Sites
- Then, click Advanced
- Add the base URL for your site to the list
- Click OK
- Then, click OK again to confirm your action
Adding the site’s path to the list of Local Intranet Zone sites may also help to fix the error. Just don’t forget to configure Internet Explorer to automatically log in using the current username and password for sites in the Intranet Zone.
4. Use the desktop client
Since the cookies issue is only something that you encounter while using the web client, one obvious choice would be to simply switch to the downloadable desktop client instead.
This software comes free of price and it can be acquired free separately or part of the Microsoft Office Suite.
By following these steps, you should no longer receive any cookie-related errors when trying to log into Microsoft Teams.
