Three Mail Folders on Mac Mail

Hi Tech,

There are three mail folder called ' RSS Feeds', ' Working Se' and ' SmsAndChats Sync' appearing on my MAC mail sidebar.  They are not my creation. From Mail account detail, I know these three folder from office365.  I access outlook web of office365,  I can see 'RSS Feeds' folder, but not another two.  I really need these three folders not showing on My MAC Mail, how can I do?  Thanks
