Microsoft Offers Workaround for Outlook.com Emails Blocked by Gmail

Google's new email authentication requirements lead to blocking of some Microsoft Outlook.com emails, prompting Microsoft to suggest a temporary fix.

Outlook.com users report issues with emails being blocked and flagged as spam when sent to Gmail accounts, affecting those with Outlook.com country domains.
Google has implemented new mandatory bulk sender authentication requirements, causing genuine non-spam emails from Microsoft Outlook to be blocked.
Microsoft advises affected users to add an Outlook.com alias to their accounts and use it to email Gmail contacts as a temporary workaround.
Google's updated guidelines aim to reduce spam and phishing by enforcing stricter spam thresholds and authentication for bulk senders from April 2024.
Microsoft is investigating the situation and working on a more permanent solution, while Google recommends reviewing its Bulk Sender Guidelines to improve email deliverability.
