Identify which Microsoft session you are ending
An Office application, the OneDrive synchronization client and the Windows user profile may use related credentials without sharing exactly the same sign-out state. List which of these is active on the device, then identify whether your goal is to remove Office activation, stop OneDrive sync or protect a shared computer. Signing out of Office alone should not be treated as proof that every related session has ended.
Save any document that is still being edited before ending a session. A document held only locally requires a different check from one already confirmed in OneDrive or SharePoint.
Test the Office app after signing out
Open an Office application again and inspect which account, if any, is displayed. Depending on the license, Office sign-out can change editing capability without uninstalling the software or deleting your documents. Test a representative file locally and separately from another signed-in device so you do not confuse activation with file availability.
If the objective is to remove Microsoft 365 applications from this device, use the uninstall guide; if it is to cancel paid billing, check the subscription account.
Verify OneDrive and the device independently
Microsoft documents that Office sign-out and the OneDrive desktop client are separate. Inspect the OneDrive app’s own account and synchronization status rather than assuming that the Office command disconnected it. On a shared or departing employee device, check relevant organizational instructions before changing Windows profile or device registration settings.
The final evidence is a clear account-state check for every service you meant to disconnect—not merely the disappearance of a name from one Office window.
Keep billing separate from signing out of Microsoft 365
Before signing out of Microsoft 365, identify any subscription tied to the app or device and verify its renewal state in the billing account, not on the device alone.
Trusted-device status after signing out of Microsoft 365
On a shared or retiring computer, distinguish Office activation, OneDrive sync and the Windows user profile before deciding access has been removed. Sign out of each service you actually used, remove the device from the account only where appropriate, and confirm that recovery and sign-in on your remaining device still work.
Signing out of Microsoft 365: verify another device or user
Your subscription can continue billing. Before finalising the Microsoft 365 sign-out, try a signed-out or second-device recovery check. After signing out of Microsoft 365, test sign-in from another device and check one shared file, role or service that should still work.
Verify the device after sign-out
Open the Office app again after signing out and confirm which account it now requests. Check OneDrive sync separately, since Microsoft documents that Office sign-out does not automatically sign out the OneDrive client. Test an important document from your remaining authorized device and confirm that your Microsoft 365 subscription status has not been mistaken for a device sign-out.
Check synced and local Office files before signing out
Confirm which documents are already synchronized and which files exist only on the computer. Save local-only work somewhere you can open without the current Microsoft 365 session, then record the account that owns the subscription. After signing out, test the files and the sign-in path you intend to use next. This separates access to documents from the subscription itself and avoids treating a sign-out as if it were a licence cancellation.
Signing out changes activation; uninstalling changes the software on the device
Signing out and uninstalling Microsoft 365 solve different problems. Microsoft says that for a Microsoft 365 subscriber, signing out removes the account’s Office license from that signed-in app state and can leave the apps unable to create or edit files until you sign in again. It also removes the recent-files list and some app settings from that session. That is an account-and-activation change, not removal of the Microsoft 365 applications from the computer.
Uninstalling is the device-software action. Microsoft separately states that uninstalling Microsoft 365 removes the applications but does not remove the documents, workbooks or other files you created with them. So if the goal is to hand a device to someone else, troubleshoot an installation, or stop a particular account from being active, choose the action that matches the real goal rather than treating sign-out and uninstall as interchangeable.
One more boundary matters: signing out of Office is not the same as signing out of the OneDrive sync app, and signing out does not cancel a Microsoft 365 subscription. Before changing anything, record which Microsoft account owns the subscription, where important files are stored, and whether OneDrive is still syncing independently.

Sign-out is not uninstall
This page checks Office activation and OneDrive sessions after sign-out. If you intend to remove the apps themselves from the computer, use the uninstall guide instead. Read the related, differently focused guide.

Signing out is an account-session decision
This article is about ending or changing the signed-in Microsoft 365 session on a device. It concentrates on identity, account access, sync state, and what should be checked before the session is removed.
Uninstalling Office is a different operation: it removes local applications rather than simply ending a signed-in session. Use the uninstall guide when the software installation itself is the thing you plan to change.
