Microsoft has announced retirement of the Outlook Web Access (OWA) mobile application for iOS and Android. Moving forward, the Outlook mobile application will be the preferred option. In April the OWA application will be removed from the online stores and on May 15, 2018 the OWA application will cease to function. For those that have OWA connected to an Office 365 tenant they will receive messages regarding the change and a link to the Outlook mobile application. However, if OWA is used to work with an on-premise Exchange server, then no notification is received.
To avoid a barrage of support calls due to the pop ups or OWA “breaking” on May 15th, begin pro actively communicating the changes and moving users to the Outlook application. Using PowerShell, you can determine who has configured the OWA application. Also, if your users are using OWA to remotely work with shared mailboxes, they will need to use OWA in the device’s browser client until the Outlook application offers this feature later in 2018.
If you still have OWA app users in your Office 365 environment, Microsoft will be posting a notice to your Message Center advising of the retirement of the apps.
For on-premises Exchange organizations, you can identity OWA app users with the following PowerShell command in the Exchange Management Shell:
[PS] C:\>Get-MobileDevice -OWAforDevices
