EDIT: We have found the issue and have since fixed it. Emails should be able to receive activation emails. If any issues remain with not receiving @eastmans.com emails, please send an email at webmaster[at]eastmans.com
We are currently experiencing an issue with all Microsoft related email clients with some users who do not receive an activation email. If your email ends with @live.com, @hotmail.com, @msn.com or @outlook.com, there is a possibility that you may not receive any emails from our forum software and may not be able to activate through your email. In the meantime, if this is the case, please send a message here telling us that your email is not being received for activation and we will activate it manually. We apologize for this inconvenience and hope to have it resolved very soon.
