Recently i tried to send emails to my other domain from o365 account which contains more than 30 recipients of my other domain. There also recipients from my o365 domain. Main issue is o365 domain user received the mail but my other domain user didn't get the mail. It shows pending on mail flow menu.

    @Uday Chandra Sarker

    It shows pending on mail flow menu.

    Could you provide a screenshot about this one?

    send emails to my other domain

    Does those mailboxes hosted on another mail server? Or, hosted on your Office 365 but use your customized domain name?

    If those mailboxes hosted on another mail server, I would suggest you try to send email from Office 365 to one of mailboxes on another mail server directly, check whether could send email successfully. If you still cannot send email successfully, I think this issue is related with the MX record for your another mail server. Please have a check about it.
