Using Graph API to Disable Outlook on the Web (OWA)

Question

Hello everyone,

I have a question regarding email provisioning through Microsoft Graph API. Is it possible to use Graph API to disable Outlook on the Web (OWA)? We are implementing a solution where we create an Azure account and provision an Office 365 E1 license for email. Our client wants OWA to be disabled when the account is created and assigned with the license. If disabling OWA with Graph API is not possible, are there any other ways to achieve this use case?

Thank you in advance.

Hi @Billy

According to the documentation, the Graph API does not yet provide an endpoint for disabling OWA. You can disable OWA using other methods, such as EAC or Exchange Management Shell. See the documentation below for details on how to disable OWA:

Hope this helps.

Hello Billy,

Thank you for reaching out to Microsoft Support!

Disabling Outlook on the Web (OWA) directly through the Microsoft Graph API is not currently supported. However, you can achieve this by using PowerShell with the Exchange Online module. Please refer documentation.

Hope this helps.
