Sent emails from mobile not syncing with Outlook Sent items

Dear Zoho Mail Support,

We are using outlook in computer and email setup in mobile for users. When users are sending email from mobile it is not syncing to outlook sent items folder but at the same time it is appearing on the webmail sent items folder.

We need it to appear on outlook sent items folder as well. 

Please help since this is a serious issue. Thanks,
