PROBLEM

In Microsoft Office 365, when you try to open Microsoft Outlook Web App by using a web browser such as Safari, you receive the following error message:

Cannot use this ID to access this service. Please sign-in with a different ID.

When you use Windows Internet Explorer, Outlook Web App opens successfully.

CAUSE

This issue occurs when you try to open Outlook Web App by using a URL that points to a site that requires Microsoft account (formerly Windows Live ID) credentials. And, this site doesn't accept a user ID. For example, you use the following URL: 

http://www.outlook.com/<username>

SOLUTION

To resolve this issue, use a URL that resembles the following to access Outlook Web App in Office 365:

https://www.outlook.com/<domainname>

For example if your domain is contoso.onmicrosoft.com, the URL that you'd use is as follows: 
https://www.outlook.com/contoso.onmicrosoft.com
