The method for erasing browser cookies and cache differs depending on the browser. For the sake of this blog post, I’ve prepared instructions for removing cookies on Chrome which is the most widely used browser.

Step by step process – How to clear cache data from the browser

  • Firstly, open your chrome browser.
  • After that click on the three dots.
  • Hover over “History”.
  • Now click on “History”.

Alternatively, you can click on Ctrl+H to enter the history page a lot quicker.

Browsers save a lot of information from other websites on your request if you accept cookies. This makes it easy for websites to store information such as login details, shopping cart entries, or address boxes. If you ever need to return to these at a later date you don’t have to go around looking for that information as it’s there as soon as you open the website. You can block and restrict cookies that are not recommended because certain cookies may help to speed up your browsing experience. You can delete the browser cookie information at any time, and it can even help with solving the issue this blog is addressing. Follow-through:

  • Ensure “Cookies and other site data is selected”.
  • Then click on “Clear data”.
  • Finally, close the browser.

You use your browser on a daily basis to access a variety of online services, such as Facebook, online banking, and online purchasing. Your browser has a tendency to save information, which might create issues logging in or loading websites over time.

Cookies and your cache provide important services and are typically beneficial, but they can also cause issues. Browsers store websites you’ve visited so they load faster the next time you visit them, but this might cause problems if the site or software you’ve visited has been modified since you last visited. As a result, clearing your browser’s cookies and cache may be helpful in recovering web access to Outlook.

Clearing your cache, or browser history, and clearing cookies on a regular basis is always a good practice. After doing the clean-up, your privacy will be more secure, and your browser will function better; nevertheless, your saved user names and passwords will be wiped, and you will need to re-enter them.

Try incognito mode to fix error 0 in Microsoft 365 Admin Center

Incognito mode is a private browser extended from what you use normally, this has a completely clean slate without any cookies of cached data from past sessions or any login credentials stored. It is basically reminiscent of a new browser from an unused account, this will help avoid login issues you may have present. Follow through for more information on incognito mode and how it can fix the login error 0.

  • Firstly, open your chrome browser.
  • After that click on the three dots.
  • Click on “New incognito window”.

The incognito browser will open in a new window, this again is for security reasons not sharing information between different browsers. Login issues may be present due to cached credentials however despite the cached being cleared certain information from the login session may remain active on the browser unless completely cleared. Using an incognito tab changes that and allows you to get a fresh new login browser without having to clear your entire browsing data.
