The Error 0x80072f05 prevents the user from installing or updating their application from the Microsoft Store. In addition to Microsoft Store, this error sometimes also pops up in Microsoft Outlook or other Mail clients and the users are unable to receive any new emails on their application. Most of the time this error can easily be resolved by changing the Date and Time on the system.
However, there can also be other reasons for this error. For instance, the Microsoft Store might not be able to connect to its server, or there can be problems in your system’s registry, or a missing or corrupt system file.
Method 1: Setting Up Date And Time
In this method, we will correct the Date and Time on the system according to the user’s Time Zone. This is very important as there are software and services that perform their authorization from the internet and if the Time or Date is incorrect then the access to those services to the resources on the internet is denied. This can be caused by some malware installed on your system to change your Time Zone or the user must have mistakenly chosen the wrong Time zone. You can avoid this by setting your Time and Date to an Internet-based Time Server.
- In the Start Menu, Type Date & Time and open the Date & Time Settings
- Make sure that you have the correct Time Zone Selected under the Time Zone
- Turn the option on where it says Set time automatically and click Sync Now under Synchronize Your Clock
- Now open the Microsoft Store and see if the problem has been resolved.
Method 2: Turn Off Proxy Settings
Proxy Server acts as an intermediary between your computer system and the internet, When you send a request, it is sent to the Proxy Server, and then it is sent to the server on the Internet. If this setting is enabled, then it can interfere with the authentication process because the Server that is trying to authenticate the user; it might think that you are accessing your account from a different device or location and will consider this as an attempt by someone to steal your credentials and will block the authentication request. Therefore it is suggested to Turnoff your proxy settings.
- Open the Windows Menu and Click on Settings
- Click on Network & Internet
- In the left side-pane click on Proxy
- Under Manual Proxy Setup, make sure the option Use a Proxy Server is turned off
