I have added another user's email account to my OUtlook365 account using their credentials . How do I remove that account - not just hide it.

    If this was added as a full email account in new Outlook for Windows:

    1. Open View > View settings.
    2. Go to Accounts > Your accounts.
    3. Under Email accounts, find that other user’s account.
    4. Select Manage next to it.
    5. Under Account details, select Remove.

    Important:

    • This removes the account from Outlook only. It does not delete the actual mailbox or email account.
    • Any offline cached content for that account is deleted when the account is removed.
    • If it is a non-Microsoft account, Outlook may offer Remove from only this device or Remove from all devices. Remove from all devices can permanently remove Microsoft Cloud data for that account across Outlook clients.

    If what was added was another person’s mailbox under an Exchange account rather than a separate full account, remove it this way:

    1. In Outlook, select File > Account Settings > Account Settings.
    2. On the Email tab, select the Exchange account, then select Change > More Settings.
    3. Open the Advanced tab.
    4. Under Open these additional mailboxes, select the other person’s mailbox.
    5. Select Remove.

    Hi Regan,

    Since you’re using new Outlook, please follow these steps:

    Option 1: If you’re using new Outlook, go to:

    • Settings > Accounts > Email accounts.

    User's image

    • Locate the other user’s email account.
    • Select Manage, then choose Remove account.
    • If prompted, choose Remove from this device. This removes the account from Outlook without deleting the actual email account.
    • Restart Outlook.

    If the mailbox appears under Shared with me, go to Settings > Accounts > Shared with me, expand the mailbox, and select Remove.

    User's image

    Please note that if it was automatically added by your administrator, only the administrator can remove the mailbox permission.

    Option 2: If the account cannot be removed directly, you can create a new Outlook profile containing only your own account:

    • Close Outlook.
    • Open Control Panel and search for Mail.
    • Select Mail (Microsoft Outlook) > Show Profiles.
    • Select Add, then create a new profile using only your email account.
    • Set Always use this profile to the new profile.
    • After confirming everything works, return to Show Profiles and remove the old profile.

    Please note that removing an account or profile from Outlook does not delete or deactivate the actual email account. It only removes its connection and locally cached data from that computer.

    You may find further guidance here:

    I hope the information I shared earlier was somewhat helpful in addressing your issue. If you have any further questions or updates, please don’t hesitate to share.

    Best regards,
