Some of my gmail recipients are randomly not receiving my outlook.com emails. The emails are in my sents and I am not receiving any notice of delivery issues. What can I do to fix this on my end as new recipients wouldn't have notice to look for emails from me.

    A personal Microsoft Account (e.g.outlook.com, hotmail.com) does not provide Non-Delivery Reports. If your mail was rejected by Google, you will not get any notification.

    Because outlook.com is the source of so much spam, Google bounces almost everything from an outlook.com account with no "reputation". You can improve your standing with Google by having your recipients add your email to their Google Contacts and replying to your emails.

    Be sure that no one you are sending to ever reports your emails as Spam.

    But there is no magic bullet. It takes time and an accumulation of "normal" traffic.

    For Outlook.com, the most relevant causes are recipient-side spam filtering, temporary server issues, account sending restrictions, and message content/signature issues.

    Try these checks on the Outlook.com side:

    1. Confirm the message is not over the send limit conditions
      • If the Outlook.com account is newly created, it can have a temporary low sending quota until credibility is established.
    2. Remove anything in the message that may trigger filtering
      • If the message has a signature, remove the signature and resend a test message.
      • If the message has an attachment larger than 25 MB, Outlook.com cannot send it.
    3. Improve recipient acceptance
      • Ask affected Gmail recipients to add the Outlook.com address to their safe senders list.
      • Add the recipients to Contacts in Outlook.com.
    4. Check whether this is a temporary delivery condition
      • Some delivery problems such as connection timeout or remote server connection issues can resolve on their own. If no non-delivery report is returned, wait a short time and resend a test message.
    5. If Gmail is blocking the message as spam or low reputation
      • Outlook.com guidance for blocked/listed errors is that the recipient’s email provider support team must unblock the account or domain.
      • A known Outlook.com issue affecting some country domains sending to Gmail was marked fixed.
    6. If Outlook.com account validation is involved
      • Outlook.com has a documented workaround for send issues caused by Microsoft account validation problems: follow the Microsoft account security info and verification steps from the Outlook.com known issues page.

    If the problem is only affecting some Gmail recipients and there is no bounce message, the supported Outlook.com actions are to simplify the message, remove the signature, avoid large attachments, add recipients to Contacts, and have recipients safelist the address.
