Frequently Asked Questions

Which account, file, or app should I use when I click Share / Start sharing?

Click Share / Start sharing. Use the Install apps control after signing in at microsoft365.com with the account that owns or receives the license.

What result should appear when I ask her to open the email and click Accept > Join now?

The device list is not always the installer source. Confirm the subscription under Services & subscriptions and install from the signed-in Microsoft 365 portal. Confirm the account type, product version, ownership, and permissions before assuming the control is unavailable.

What should I preserve before I open any of the apps (for example, Word)?

Compatibility depends on the Office version and operating system. Unsupported editions may install poorly and no longer receive security updates; use a supported alternative. Keep the relevant backup or confirmation until you have checked the result.

Where should I verify the final result after I install Microsoft 365 on another device?

Check that your subscription is still active. Reopen the affected app or portal and confirm that the expected status persists.
