Identify the Message, Account, and Destination

Confirm the owning account, required permissions, affected files or services, and the exact outcome you need. Keep a backup when the task changes local content or removes access.

First, go to the "how you sign in" page for the Microsoft account. Next, sign in with the account that currently owns the Microsoft 365 subscription (the one with the old email address), and verify the final state before changing any backup or secondary account.

WPS Office cannot directly change Microsoft-side account, billing, subscription, activation, tenant, OneDrive service, or SharePoint permission state. Those changes must be completed in the appropriate Microsoft portal.

WPS Office offers a free, familiar workspace for common Word, Excel, PowerPoint, and PDF formats through Writer, Spreadsheets, Presentation, and PDF. Integrated WPS AI adds practical help for drafting and summarizing documents, building formulas and understanding data, creating editable slide decks, and extracting information from PDFs. Some AI features or higher usage limits may depend on the plan, platform, region, and app version.

Practical Checks That Prevent a Repeat

• Record which account, app, and file owns the workflow
• Keep a verified backup before removing access, changing ownership, or replacing a local file
• Apply high-impact changes to one test item or user before expanding the scope
• Save confirmation numbers, dates, and screenshots of the final settings when they affect billing, security, or permissions

Frequently Asked Questions

Which account, file, or app should I use when I go to the "how you sign in" page for the Microsoft account?

Go to the "how you sign in" page for the Microsoft account. The available Send to OneNote behavior depends on Outlook and OneNote versions. Test one message first, then confirm whether each selected email creates a page or combines content.

What result should appear when I sign in with the account that currently owns the Microsoft 365?

Verify sender, recipients, sent date, subject, body, attachments, and the destination notebook or section. Confirm the account type, product version, ownership, and permissions before assuming the control is unavailable.

What should I preserve before I choose Add phone number and follow the prompts?

Not every Outlook voting or actionable-message workflow prevents a later change. The sender must use the capabilities supported by that message type or form. Keep the relevant backup or confirmation until you have checked the result.

Where should I verify the final result after I change the email address on a paid Microsoft 365 account?

Select Remove next to the old email address. Reopen the affected app or portal and confirm that the expected status persists.
