Hi @George Grammatikos,


It is by default not possible to change the Conditionall Access messages.

I don't know what you case is but if you have the MCAS license, this can give you some options to Customize the error messages.


You can check the following blog post. 


Kind regards,



Hi @Mr_Helaas,


Thank you for your response.
The need is to grant access to the organization O365 apps only to devices that joined the corporate azure ad. I also wonder if we can change the default message. For example, please check the image below:

Hi @George Grammatikos,


I'am sorry it is not possible to change the default Conditional access message.


You can take a look at the MCAS solution of Microsoft were you can customize the message. I don't know which license you have but MCAS is not included in all licences.   


Kind regards,
