Exchange Email Address Policy
Posted on 2015-01-12
I walked into a problem today and I really don’t know how to begin to fix this. A little quick history about this Exchange 2010 setup. I have two servers in a DAG and two CAS Servers. On Friday evening 1/12/14 I have a round of Windows Updates and I installed Exchange 2010 SP3 Update Rollup 8. Everything went well or at least I thought. On Monday I started getting calls that people who were sending email to internal distribution groups we looking like they were being sent out to the local user but would just disappear and never reach their intended destination. After looking into the Mail flow troubleshooter it looks like I am seeing this:
The email address for recipient firstname.lastname@example.org was updated to the email address email@example.com. The message is in the process of being delivered. The funny thing it the messages are trying to go to our old domain which is simply missed the word “the”.
I determined that the update must have done something to the default email address policy. Now this 2010 environment was upgraded from Exchange 2003 almost 4 years ago. When I look at the default email address policy in the EMC I don’t see anything but when I look in the console and do a
get-emailaddresspolicy I get a warning that I need to include the –IncludeMailboxSettingOnlyPolicy. When I do that I can see the default policy in the console.
I tried to create a new policy and applied it and it seemed to work but I can’t get rid of the old default policy, now when I do the get-emailaddresspolicy –includemailboxsettingonlypolicy I can see both polices. I tried the remove-emailaddresspolicy with no luck.
Anyone that can offer some assistance, I would greatly appreciate it. I still can’t get my distribution lists to work but I feel that solving this problem may help me in that direction.
