Hi there,
Exchange 2013 CU21 running on Win2012r2 std server, so far so good.
Recently observed that there are a lot of event 12018 MSExchagneTransport as below screen dump
After login to EAC also received similar alert as below screen dump
I've done my research, it seems I just need to click the Renew button to fix it.
However this is my production email server & I don't have any spare resources for testing, just wondering if such renew process will result in any email service temporary outage?
Also for such process, typically how long to finish, within a few mins or need some 30 mins or so?
Should you need more info, I'm available to further discuss with you.
Thanks in advance for your help!
