Merging accounts in portal.office.com is not directly supported. Each Microsoft account is designed to be unique, with its own data, subscriptions, and settings. However, you can link multiple accounts by sharing access to files or using shared resources like OneDrive or Microsoft Teams. If youre trying to consolidate data, you can manually transfer files, emails, or calendar entries between accounts. For work or school accounts, your IT administrator might assist in consolidating or managing permissions. To streamline access, consider signing into both accounts simultaneously using different browsers or incognito mode. Visit portal.office.com for account management options.
