Hi @Ryan, Samantha
Welcome to our forum!
This error message usually indicates an issue with Outlook’s data files or synchronization problems. Here are some steps you can try to resolve this issue:
- Sometimes this error occurs when Outlook data files corrupt, therefore, you can try to Repair Outlook Data Files (.pst and .ost).
- Check your account settings: If you’re using an IMAP account, you might need to specify the “Inbox” in the root folder path.
- Create a new Outlook profile: In some cases, creating a new profile entirely can resolve persistent issues with sending emails.
