After more than 20,000 ARRL members had their arrl.net and arrl.org e-mails blocked by Microsoft, the issue has been resolved. According to ARRL Information Technology Manager Michael Keane, K1MK, Microsoft told the ARRL that the mail blockage from ARRL servers to Microsoft domains (including msn.com, hotmail.com, live.com and outlook.com) was mitigated as of Sunday, March 10. Microsoft cautions that this mitigation may take 24-48 hours to replicate completely throughout their systems.
