Scenario: You have an Office 365 account, work or personal, licensed to you or your organisation. You also have need to occasionally log into Office 365 accounts to access Outlook. These maybe created for you by other organisations, to which you do not want their credentials saved on your computer as they may interfere with your credentials for O365. Also, you may not want multiple Outlook profiles and data hoarding disk space on your computer.
Alternative:
I would recommend using Chrome incognito mode or Firefox new private window mode to access the link below. This will ensure that any other Microsoft Office 365 services that you may use, personally or at work, are not interfered with when you sign in with the credentials found below. Essentially this ensures the details are not saved in your preferred browser; which can lead to a “mix up” with saved usernames and passwords associated with Office 365.
Chrome
To put Chrome into incognito mode, open a chrome Windows as you normally would. Once Chrome is open, press CTRL + Shift + N on your keyboard and this will open another Chrome window incognito mode.
In the Chrome incognito address bar copy in the link below and press enter
https://outlook.office365.com/owa
From here you will be able to sign in to Outlook Office 365, just enter the e-mail address then click next and enter the password and click on the sign in button.
When you see the option to sign in, click on the NO button. (As you’re in the incognito mode the credentials will not be remembered anyway.)
You’ll now be signed into Outlook Web Access, also referred to as OWA.
Once you have exited Chrome incognito mode the connection will be terminated and you will need to go through the sign in process again to reconnect.
Firefox
Open Firefox and then press CTRL + Shift + p on your keyboard. This will spawn a FireFox Private Browsing window.
In the Firefox Private Prowsing address bar copy in the link below and press enter
https://outlook.office365.com/owa
From here you will be able to sign in to Outlook Office 365, just enter the e-mail address then click next and enter the password and click on the sign in button.
When you see the option to sign in, click on the NO button. (As you’re in the incognito mode the credentials will not be remembered anyway.)
You’ll now be signed into Outlook Web Access, also referred to as OWA.
