Problem

Microsoft 365 is a popular cloud-based service that offers various applications and features for personal and professional use. However, sometimes you may encounter an error message when you try to sign in to Microsoft 365. The error message says: “Another account from your organization is already signed in on this device. To add this account, you’ll need to sign out of the other account and sign in again.”

This error can be frustrating and confusing, especially if you have multiple Microsoft 365 accounts for different purposes. You may wonder why you can’t sign in with more than one account at the same time, or how to switch between accounts without signing out and signing in again. In this article, we will explain the causes of this error, and provide you with some simple solutions to fix it. We will also answer some frequently asked questions related to this topic.

Causes of the Microsoft 365 Error: Another Account from Your Organization is Already Signed In

The main cause of this error is that Microsoft 365 does not allow you to sign in with more than one account from the same organization on the same device. This is because Microsoft 365 uses a single sign-on (SSO) feature that automatically signs you in to all the applications and services that are associated with your account. This feature is designed to enhance your security and convenience, but it also means that you can’t sign in with another account from the same organization without signing out of the current one.

Another possible cause of this error is that you have signed in with a personal Microsoft account instead of a work or school account, or vice versa. Microsoft 365 distinguishes between personal and organizational accounts, and you can only sign in with one type of account at a time. If you try to sign in with a different type of account, you will get the error message.

Solutions to Fix the Microsoft 365 Error: Another Account from Your Organization is Already Signed In

Depending on the cause of the error, there are different solutions that you can try to fix it. Here are some of the most common and effective methods that you can follow:

Solution 1: Sign Out of the Current Account and Sign In with the Desired Account

The simplest and most straightforward solution is to sign out of the current account that is causing the error, and sign in with the account that you want to use. This will allow you to access the applications and services that are associated with the desired account. To sign out of the current account, you can follow these steps:

Step 1: Open any Microsoft 365 application, such as Word, Excel, PowerPoint, Outlook, etc.

Step 2: Click on the File tab in the top left corner of the screen.

Step 3: Click on Account in the left sidebar.

Step 4: Under User Information, click on Sign Out.

Step 5: Close the application and reopen it.

You will be prompted to sign in with your account. Enter the email address and password of the account that you want to use, and click on Sign In.

Alternatively, you can also sign out of the current account from your web browser, if you are using Microsoft 365 online. To do this, you can follow these steps:

Step 1: Open your web browser and go to [https://www.office.com/].

Step 2: Click on the Sign In button in the top right corner of the screen.

Step 3: Enter the email address and password of the current account that is causing the error, and click on Sign In.

Step 4: Click on your profile picture in the top right corner of the screen, and click on Sign Out.

Step 5: You will be redirected to the Microsoft 365 sign-in page. Enter the email address and password of the account that you want to use, and click on Sign In.

Solution 2: Use Different Browsers or Incognito Mode for Different Accounts

If you want to sign in with more than one account from the same organization on the same device, you can use different browsers or incognito mode for different accounts. This will allow you to access the applications and services that are associated with each account separately, without interfering with each other. For example, you can use Chrome for one account, and Firefox for another account. Or, you can use Chrome in normal mode for one account, and Chrome in incognito mode for another account. To use incognito mode, you can follow these steps:

Step 1: Open your web browser and go to [https://www.office.com/].

Step 2: Click on the Sign In button in the top right corner of the screen.

Step 3: Enter the email address and password of the account that you want to use, and click on Sign In.

Step 4: Click on the menu button in the top right corner of the screen, and select New Incognito Window or New Private Window, depending on your browser.

Step 5: A new window will open in incognito mode, which means that your browsing history and cookies will not be saved. You can use this window to sign in with another account from the same organization, and access the applications and services that are associated with it.

Solution 3: Use Different Profiles or Accounts for Different Accounts

Another option to sign in with more than one account from the same organization on the same device is to use different profiles or accounts for different accounts. This will allow you to create separate environments for each account, with their own settings, preferences, bookmarks, extensions, etc. For example, you can use different profiles in Chrome, or different accounts in Windows 10. To use different profiles in Chrome, you can follow these steps:

Step 1: Open your web browser and go to [https://www.office.com/].

Step 2: Click on the Sign In button in the top right corner of the screen.

Step 3: Enter the email address and password of the account that you want to use, and click on Sign In.

Step 4: Click on the profile picture in the top right corner of the screen, and select Manage People.

Step 5: Click on the Add Person button in the bottom right corner of the screen.

Step 6: Enter a name and choose an icon for the new profile, and click on Add.

Step 7: A new window will open with the new profile, which means that you can customize it according to your preferences. You can use this window to sign in with another account from the same organization, and access the applications and services that are associated with it.

To use different accounts in Windows 10, you can follow these steps:

Step 1: Click on the Start button in the bottom left corner of the screen, and select Settings.

Step 2: Click on Accounts in the left sidebar.

Step 3: Click on Family & other users in the left sidebar.

Step 4: Click on Add someone else to this PC under Other users.

Step 5: Follow the instructions to create a new account, and choose a name and password for it.

Step 6: Click on the Start button in the bottom left corner of the screen, and select the new account that you have created.

Step 7: A new session will start with the new account, which means that you can customize it according to your preferences. You can use this session to sign in with another account from the same organization, and access the applications and services that are associated with it.

FAQs Related to the Microsoft 365 Error: Another Account from Your Organization is Already Signed In

Here are some of the frequently asked questions related to the Microsoft 365 error that says another account from your organization is already signed in:

Question: Why can’t I sign in with more than one account from the same organization on the same device?

Answer: Microsoft 365 uses a single sign-on (SSO) feature that automatically signs you in to all the applications and services that are associated with your account. This feature is designed to enhance your security and convenience, but it also means that you can’t sign in with another account from the same organization without signing out of the current one.

Question: How can I switch between accounts without signing out and signing in again?

Answer: You can use different browsers or incognito mode for different accounts, or use different profiles or accounts for different accounts. This will allow you to access the applications and services that are associated with each account separately, without interfering with each other.

Question: What is the difference between a personal and an organizational account?

Answer: A personal account is an account that you create for yourself, using your personal email address, such as Gmail, Yahoo, or Outlook.com. An organizational account is an account that is created for you by your organization, such as your school or workplace, using your organizational email address, such as @school.edu or @company.com.

Question: How can I tell which type of account I have?

Answer: You can tell which type of account you have by looking at the email address that you use to sign in to Microsoft 365. If your email address ends with a domain name that is owned by your organization, such as @school.edu or @company.com, then you have an organizational account. If your email address ends with a domain name that is not owned by your organization, such as @gmail.com or @yahoo.com, then you have a personal account.

Question: Can I sign in with a personal and an organizational account at the same time on the same device?

Answer: Yes, you can sign in with a personal and an organizational account at the same time on the same device, as long as they are not from the same organization. For example, you can sign in with your personal Gmail account and your work account from your company, but you can’t sign in with two work accounts from the same company.

Question: How can I sign in with a personal and an organizational account at the same time on the same device?

Answer: You can sign in with a personal and an organizational account at the same time on the same device by using the same methods that we have mentioned above for signing in with more than one account from the same organization. You can use different browsers or incognito mode for different accounts, or use different profiles or accounts for different accounts.
