Microsoft has acknowledged that some Outlook.com users are encountering problems with their emails being blocked and marked as spam when sending to Gmail accounts. The issue affects users with Outlook.com country domains, and Google's mail server is sending notifications to affected users explaining that their messages have been stopped due to suspicions of being spam. Microsoft suggests impacted users add an Outlook.com alias to their accounts as a temporary fix. Google's new anti-spam guidelines are also mentioned, which include stricter measures for bulk senders to improve email deliverability and defend against spam, phishing, and malware.
Microsoft has warned Outlook.com users about a known issue that prevents them from sending emails with attachments. Users are encountering "Error code 550 5.7.520 Message blocked" errors when attempting to send such emails. As a workaround, Microsoft suggests uploading the files to OneDrive and sharing the link with recipients. Users can also copy the link of an Office or OneDrive file and paste it directly into their email. Microsoft is actively working on resolving the issue while providing temporary solutions for affected users.
Microsoft experienced an Outlook.com bug that prevented users from searching their emails, which has since been fixed. However, a more significant issue is a flaw in Teams that allows for the sending of phishing emails and malware to other users. Microsoft has stated that they will not be fixing this flaw and instead encourages users to practice caution when clicking on links or opening unknown files. The flaw can be exploited through a Python-based automated attack called TeamsPhisher, developed by a US Army red teamer, which bypasses security controls and sends malicious attachments to external Teams users.
Microsoft is investigating an ongoing bug in Outlook.com that is preventing users from searching their emails and triggering 401 exception errors. The issue has been ongoing for almost 11 hours, and Microsoft is working to determine the source of the errors and find a solution. The search function is not working on the web, but the mobile version seems unaffected. Users have also reported difficulties contacting Microsoft 365 personal support. The company has not yet provided information on which regions are impacted.
Outlook.com is experiencing outages due to technical issues, according to Microsoft, but hacktivists known as Anonymous Sudan claim to be behind the disruptions, performing DDoS attacks on the service to protest US involvement in Sudanese affairs. The group has taunted Microsoft and demanded a $1 million payment to stop the attacks. The service has been sluggish and plagued by outages over the past 24 hours, causing disruptions for global Outlook users.
