How to Manage Multiple Microsoft 365 Accounts on One Device at the Same Time



Microsoft Office 365 has a helpful feature. One subscription can be on multiple devices. You probably have a single sign-in at work that you can use on your phone and computer. At home, however, a family account gives you up to six different accounts you can share with your family.

Issues with Having Multiple Microsoft or Office 365 Accounts

Microsoft has made it easier to transfer between Microsoft 365 (formerly Office 365) accounts without logging out. However, this in no way implies that changing accounts is simple.

For example, you won’t be able to use multiple logins to access the same Word document. There must be a third-party app for it to function. For example, you can open a Word document sent to one inbox and an Excel file sent to another, which is helpful; however, if you try to open two Word documents simultaneously in different programs, you will run into some difficulties.

Another common mistake experts make attempting to sign in using a username already in use. You must sign out of Office 365, restart your computer, and select “This app only” when re-logging into the Office 365 app if the error message “Sorry, another account from your company is already logged in on this computer” displays.

There are numerous advantages to working from home, but there are also some challenges. In increasing cases, users report that their Microsoft 365 for personal use and Microsoft 365 for business are incompatible.

Using two distinct browsers (Microsoft Edge and Google Chrome or Mozilla Firefox) or an “In Private” and “Incognito” window within the same browser will do this.

Here are the steps to take to accomplish this using your preferred web browser:

Using Google Chrome to Manage & Use Multiple Microsoft 365 Accounts at the Same Time

  • Launch Chrome and sign in to your Office 365 account at outlook.office365.com
  • Choose a menu item (the three lines “hamburger” icons in the top-right corner)
  • Choose “New Incognito Window” by pressing the shortcut keys CTRL + SHIFT + N
  • Open a new incognito window and sign into your second Office 365 account there

Using Microsoft Edge to Switch & Manage Different Microsoft Office 365 Accounts on One Device

Option 1: Using InPrivate Browsing

  • Log in to a Microsoft 365 account you have
  • Select the Tools option from the top toolbar
  • Hover your cursor over the Safety Option by going there
  • Select “InPrivate Browsing” from the menu. You’ll get a new window after doing this
  • Log into a different Microsoft 365 account in the InPrivate Browsing window. Ctrl + Shift + P are the keyboard shortcut for this, which will make things simpler

Option 2: Adding Profiles

  • Open a fresh Microsoft Edge window for browsing
  • Click on the user profile image located in the toolbar’s upper right corner
  • There are three choices available: Add a profile, Browse as a guest, and Browse in Kids Mode
  • Select Add profile
  • After that, you will be directed to sign in to sync your data or proceed without doing so
  • Select the one that best meets your needs, then launches your search

Using Mozilla Firefox to Use & Manage Multiple Microsoft 365 Accounts

  • Launch Firefox and sign into one Office 365 account
  • Choose “Menu” (the three lines “hamburger” menus in the top right corner)
  • Choose “New Private Window” by pressing the shortcut keys CTRL + SHIFT + P
  • Use the new private window to sign into your other Office 365 account

Wrapping it Up

Microsoft has made it easier to transfer between Office 365 accounts. Switching between accounts is now as easy as clicking your profile picture on the top right when logged into several accounts. As long as you’re using separate programs, you can even manage many accounts simultaneously.
