When I log in to my office 365 account it says that I am already logged in within the organisation as i was previously logged in with another login which no longer exists. Can you help me to clear the background data that is making the system thing it is already logged in

    Hi Ansell,

    This usually happens because the browser still has saved cookies or sign-in information from the previous organization account.

    To resolve the issue, please follow these steps:

    1. Clear the browser cache and cookies
    • Launch the browser, and press Ctrl + Shift + Delete to open the Clear browsing data utility. 
    • Now, select All time from the Time range dropdown menu, tick the checkboxes for Cookies and other site data and Cached images and files, then click on Clear data towards the bottom. 

    Delete browsing data X Time range Last hour > Browsing history 22 items. Includes autocompletions in the address bar. Download history None Cookies and other site data From 41 sites. Signs you out of most sites. Cached images and files Frees up less than 320 MB. Some sites may load more slowly on your next visit. Passwords None Autofill form data (includes forms and cards) This will clear your data across all your synced devices signed in to To clear browsing data from this device only, sign out first.

    1. Use a private browsing window
    • Open an Incognito window in your browser.
    • Go to https://www.office.com and sign in with the current account.
    1. Create a separate browser profile
    • Open your browser browser.
    • Select your profile icon in the upper-right corner.
    • Select Set up a new profile.
    • Sign in using your current Microsoft 365 work account.
    • In the new profile window, visit https://www.office.com and try signing in again.
    1. Remove the old account from Windows
    • Go to Settings > Accounts > Access work or school.
    • If the previous organization account is still listed, select it and choose Disconnect. Please only remove the old account that is no longer in use.
    1. Clear cached credentials: 
    • Go to Control Panel > User Accounts > Credential Manager > Windows Credentials    
    • Under the section Generic Credentials, look for any entries that has Outlook, Office or having your email address in the name and remove them. 
    • Restart your computer.
