@Sangeetha Priya S Thanks for reaching out. The error message you are seeing indicates that some of the connections in your Logic App are not authorized. This can happen if the password for the user account that is used to send emails has been reset, as you mentioned.
To fix this issue, you will need to reauthorize the connection for the email sender in your Logic App. Follow the prompts to sign in to the account and authorize the connection.
Once you have reauthorized the connection, try saving the workflow again.
Let me know if you have any other questions.
