How to Remove Outlook Mobile Data After an Employee Leaves
Product
Microsoft 365 Outlook mobile
Device & OS
not provided
Scenario
An employee leaves, and the administrator must prevent continued access to cached mailbox data on a mobile device after changing the Microsoft 365 password.
Observed behavior
Changing the Microsoft 365 user password does not necessarily remove previously synchronized Outlook data from the mobile device.
Before you start

Confirm whether the mobile device is enrolled in mobile device management (MDM) and whether the account still appears as an active device in the Exchange admin center before choosing a removal or blocking method.

Solution 1Recommended

Remotely wipe the device through the organization's MDM solution

Use this when the device is enrolled in MDM and you need to erase cached Outlook mailbox data immediately.

A remote wipe removes Outlook mobile data and can also remove other organization data from the device, depending on the wipe type. It is the most reliable way to prevent continued access when a password reset is not enough.

1
Open the MDM admin center

Sign in to the Microsoft 365 admin center or Intune admin center with an administrator account.

2
Locate the departed employee's device

Select Devices > Active devices, or the equivalent mobile device list in your MDM console, then search for the employee's device.

3
Issue a remote wipe

Select the device, choose Wipe or Remove company data, and confirm the action.

Remotely wipe the device through the organization's MDM solution
Cached data removed: A successful remote wipe removes synchronized mailbox data even if the Microsoft 365 password change did not.

Frequently Asked Questions

Does changing the Microsoft 365 password remove Outlook mobile data that was already synced?

No. A password change does not reliably remove cached mailbox data from a mobile device. You should use a remote wipe through MDM or block and remove the device in the Exchange admin center.

Where can an administrator block mobile access to a mailbox?

In the Exchange admin center, go to Mobile > Mobile device access. Select the user's device and choose Block or Remove according to your organization's security policy.

Does a remote wipe remove personal data from the device?

A full device wipe removes all device data, including personal data. Some MDM solutions support a selective or company-data wipe that removes only organization data, so check your MDM policy before performing the action.

What should I do if the device is not enrolled in MDM?

Use the Exchange admin center under Mobile > Mobile device access to block or remove the mobile device partnership. This prevents future mailbox access, although data already cached on the device may remain until the mail profile is removed or the device is wiped.

Can WPS Office manage Microsoft 365 mobile device access?

No. WPS Office is a document productivity suite and does not administer Microsoft 365, Exchange, or MDM mobile access controls. Use Microsoft 365 or Intune for mobile data protection tasks.
