Office 365, Email, Exchange, OWA, 'No Match Found' error while sending to multiple recipients
The Exchange Outlook Web App uses semicolons(;) instead of commas(,) in between multiple email addresses when sending. Try entering semicolons and then attempt to send the message again.
I'm getting a 'No Match Found' error when attempting to send to multiple recipients in the Exchange OWA.
New Outlook in Exchange Online eats the commas and doesn't cause this error.
