Answer 1

Can you use the instruction here, change the email to plain text or rich text format (basically avoid the html format) and see if it goes through:

Answer 2

The error 554 5.7.0 ... message blocked because it contains content identified as spam .AS(4810) means the recipient’s email provider is treating the forwarded message as spam and rejecting it. This is on the receiving side, not a problem with the Outlook.com account itself.

Use these steps to work around it:

1. Verify the recipient address
   • Make sure the address is spelled correctly and is the current address for that contact.
   • If using Auto-Complete, remove the cached entry and retype the address:
     • Start typing the address in To.
     • When it appears in the drop-down, highlight it and delete it.
     • Type the full address again and send.
2. Reduce “spam-like” characteristics
   • Remove any large attachments and resend; if needed, save files to a cloud service and send a link instead.
   • Delete obvious marketing/tracking content from the body (unsubscribe blocks, heavy images, long footers) before forwarding.
   • Avoid forwarding the message unchanged multiple times to many recipients; instead, create a new message and paste only the needed text/links.
3. Send as a new message instead of a straight forward
   • Create a new email.
   • Summarize the content and include only the essential text or link from the original newsletter/website.
   • This often bypasses spam filters that are triggered by the original formatting or headers.
4. Ask the recipient to check their side
   • Ask them to check their Junk/Spam folder and any mail rules or forwarding that might be re-sending or blocking the message.
   • They may need to add the sender (or the newsletter domain) to their safe senders list or contact their email provider support to unblock messages.

If the problem persists only with this specific newsletter or site, contact that provider’s support and ask if their messages or links are currently being blocked by some providers; they may already have guidance.
