Microsoft has confirmed that some Outlook.com users are experiencing issues with emails being blocked and marked as spam when trying to email Gmail accounts.
Until the Outlook.com Team can address this newly acknowledged issue, Microsoft advises impacted users to add an Outlook.com alias to their accounts and email Gmail contacts using that alias.
Outlook aliases are additional email addresses associated with your Outlook.com account, and they use the same inbox, contact list, and account settings as your primary email address.
Within the "Add an Alias" section, create a new Outlook.com email address and designate it as an alias or add an existing email address as an alias, then click "Add Alias."
While Microsoft didn't share the root cause behind Outlook.com emails getting tagged and blocked as spam, Google suggests Redmond should review its new bulk sender guidelines to improve Outlook email deliverability to Gmail accounts.
