Outlook Categories

I tried searching for it but the search on this forum is just awful. Most search results are 4 years old and there’s no way to limit the search to anything useful. Anyway…

When I assign a Category to an e-mail in EM Client through an Exchange account, the name of the Category shows up in Outlook but the color is blank. When I assign a Category in Outlook, the name of the Category shows up but the color is different in EM Client than Outlook. If I rename all the Categories in Outlook, the changes don’t show up in EM Client, but shows up fine in any other Outlook client connecting to the same account.
