TikTok Allows you to send Messages to users on the platform and you also receive messages from those users, but when you disabled the message option on your account you won be able to send and receive messages from other users on TikTok aswell.
Steps to disable Messaging on TikTok
To change who can send you direct messages:
1. Tap Profile in the bottom right to go to your profile.
2. Tap the 3-line icon in the top right to go to your settings.
3. Tap Settings and Privacy.
4. Tap Privacy, then tap Direct messages.
5. Choose who you’d like to allow to send you direct messages.
Keep in mind, if you update your direct message setting to No one, you won’t be able to receive direct messages. You can still access your conversation history in the Direct messages section of your Inbox, but you can’t receive new direct messages in those conversations.
