Updated Exchange Certificate now Incoming Mail no longer works

We updated out Exchange Server Certificate on friday and now the incoming mail handler no longer works. I get the following error:

Unfortunately no connection was possible. Review the errors below and rectify:

  • SunCertPathBuilderException: unable to find valid certification path to requested target

I tried to use portecle and import the new cert into Java but this did nothing.

I guess the real question is where are the certs stored I just need to update the cert

Hi @Troy_Pawleska ,

You have to add the certificate  to the Jira keystore. Usally jira uses the keystore of the java that is coming with jira and is located here : $JAVA_HOME/lib/security/cacerts , password is changeit 


Here is also an related kb article

So I added it to the cacerts file because I found several articles on that but it's still not working, I found the cacerts file in 2 locations so put it in both. 


C:\Program Files (x86)\Java\jre1.8.0_221\lib\security\cacerts

C:\Program Files\Atlassian\JIRA\jre\lib\security\cacerts


Am i putting it in the wrong location? How can I point Jira/Java to these cacerts files?
