Answer 1

Do you use an Outlook.com mailbox or Exchange online mailbox? - we use o365

Which mail server that you want to forward meeting from? O365

Could you send email from the external mailbox to your internal mailbox successfully?

external mails are coming properly , only externally meeting requests are not being forwarded to internal users

example

1. meeting request received from xxx@Alexander Kovachev .com is forwarded to ******@mystyle.com, this meeting requested is internally forwarded to ******@mystyle.com, now this meeting request is not delivered to recipient neither notification is received regarding failure to deliver.
