Unable to connect to SMTP server

Product Name: WorkCentre 6515
Operating System: Windows 10

Hi, Can anyone help me? We have a 6605 that I did not install that connected to the sendgrip smtp server for scans to email. It's now stopped working because I think Sendgrid has changed something. We have a new id  and the p\w is apparently a created api key. We are using sendgrid for other apps apparently and it's working fine. The port no. is 587, everything is correct according to Sendgrid, but I just get 'Unable to connect'. Is there anywhere I can fix this or get a better error message?
