Hi @A O ,
Thanks for your reply!
According to your description, I have done research on New Outlook for Mac with a Gmail account. My test result is that I can't create new folder, which is the same as yours. But I can create new contact for the Gmail account in New Outlook for Mac. How did you create new contact?
In addition, based on my test, both the new folders and new contacts can be created successfully for Gmail account(As an IMAP account) when turning off the "New Outlook" switch to continue to use the old version of Outlook for Mac. As a workaround, it's suggested that you could try to turn off the "New Outlook" and continue to use the old version of Outlook for Mac.
By the way, as I know, for the New Outlook for Mac, the features it can currently support are indeed very limited. Please refer to the following article about New Outlook for Mac if you need: The new Outlook for Mac.
