Outlook 2021 can't send email to Poland.

Copper Contributor

Hi, I recently upgraded my Microsoft Office from 2016 to 2021 with my MacBook pro. Everything is fine with Office 2021 except Outlook 2021. I can receive emails without problems, and I can send most of the emails out, but all emails going to Poland (the email address ended with “.com.pl” or “.edu.pl”) are stuck in the outbox. Does anyone know the reason?

The issue you're experiencing with Outlook 2021 not being able to send emails to Poland may be related to a configuration or compatibility issue. Here are a few potential reasons and troubleshooting steps you can try:

  1. Check email settings: Ensure that your email account settings in Outlook 2021 are configured correctly. Double-check the outgoing mail server settings, such as the SMTP server and port number. Make sure they match the settings provided by your email provider.
  2. Verify recipient email addresses: Confirm that the email addresses of recipients in Poland (ending with ".com.pl" or ".edu.pl") are entered correctly. Pay attention to any potential typos or misspellings.
  3. Firewall or antivirus software: Temporarily disable any firewall or antivirus software that might be interfering with the email sending process. Sometimes, these security applications can block outgoing email connections.
  4. Test with a different email client: Try sending emails to Poland using a different email client or webmail service (e.g., Gmail, Yahoo Mail) to determine if the issue is specific to Outlook. This can help narrow down the problem and identify whether it's related to Outlook or the email server.
  5. Contact your email provider: Reach out to your email provider's support team to inquire about any known issues or restrictions regarding sending emails to Poland. They may be able to provide specific guidance or troubleshoot the issue on their end.
  6. Update or reinstall Outlook: Check for any available updates for Outlook 2021 and install them if necessary. If the issue persists, consider reinstalling Outlook to ensure a fresh installation.
