how do connect to one drive

Dear @Michael Weedon,

Thank you for posting your question in the Microsoft Q&A forum.

Based on your description, you have a new computer and already have two email accounts connected. You would like to add more email accounts and connect them to OneDrive.

For better understanding your situation, could you please confirm:
Which type of account are you using (personal account or business account)?

In the meantime, because you posted under the Business tag, I assume you are using a business account. Here are some suggestions you can refer to:

Look at the bottom‑right corner of your screen

Click the cloud icon Cloud (OneDrive)

Click setting > Account > Add an account

Enter the next email address

Sign in

For reference Sync your computer's files and folders with OneDrive

Or you can Add email account to Windows: in Search bar > Email & accounts > Add account. Sign in with the additional email

I hope information above meet your expectations. If not, please provide more information so I can support you more effectively.

On a new Windows computer, OneDrive and email accounts are set up separately. Below are the steps to connect OneDrive and add additional accounts where supported.

4. Go to the Account tab.
5. Select Add an account.
6. Sign in with the email address and password for the Microsoft account (personal) or work or school account to connect it to OneDrive.
   • Only one personal OneDrive account is supported.
   • Multiple work or school accounts are supported.

Once signed in, OneDrive folders will appear in File Explorer under OneDrive – Personal and/or OneDrive – [CompanyName].

2. Add more OneDrive accounts (where supported) Repeat the steps above from the Account tab and select Add an account again for each additional work or school account that needs to sync. Only one personal account can be added.
3. Add accounts in the OneDrive app on Windows 10 devices (if using the Store app)
4. Open the OneDrive app.
5. Select My Accounts in the upper-right corner.
6. Select Add an account.
7. Choose Microsoft account (Outlook.com, Hotmail, Live.com, MSN) for personal, or Work or school account (Assigned by your organization) for business/school.
8. Enter the email address and password for that account.

If sign-in problems occur with a work or school account, try signing in at OneDrive.com or contact the organization’s IT department.
