err

The err tag on WindowsForum.com covers discussions about error conditions and limits in Microsoft 365 and Windows environments. A recent thread highlights a new Microsoft-imposed hard limit on outgoing email from free MOERA (onmicrosoft.com) tenant domains, restricting external recipients to 100 per 24-hour rolling window starting October 2025. This change aims to combat abuse and protect delivery for legitimate customers. The tag may also include other error-related topics such as troubleshooting steps, configuration issues, or system errors encountered by users. Content under this tag focuses on practical explanations of error states and their resolutions within Microsoft and Windows ecosystems.
