Outlook on Mac not showing up Categories set through MS Graph API

Hi Team,

I'm changing mail message category using MS Graph api (eg: "Blue category"). I am not able to see the corresponding email marked as "Blue" on outlook on Mac. Where as I can see the change reflected on Outlook on Windows.

But, when I query the Messages on Graph api explorer, I can clearly see the categories are set for the mail message.

Can you please help, if this is a know issue or we need to do something in addition to see the change reflected on a Mac.

Thanks in Advance,

    Got the answer. The category names are case sensitive on Mac. Where as a name of "Blue Category" works on outlook on Windows, but not on Mac, "Blue category" does show up both on outlooks on Mac and Windows.
