HI @shanti_18

Can you check all the email address

This error can be for write a space between emails, example:

Correct: email1@email.com
Incorrect: email1@email. com

The activity “Send Outlook Mail Message” does allow spaces but “Send Exchange Email Message” don’t allow

Hi @shanti_18

Check out this thread

Multiple mail recipients

I receive following error with “,” (comma) as recipient separator: “Send Exchange Mail Message : One or more recipients are invalid.” BUT it works with “;” (semicolon) if there is NO SPACE behind, i.e. “recipient1@domain.com;recipient2@domain.com” So solution found but it would be worth to enhance the Send Exchange Mail Message activity to ignore the space.

If semicolon (; ) as separator does not work then try using comma (,) without space anywhere for example recipient1@domain.com,recipient2@domain.com. Please let me know if it works for you. It worked for me.
