I have installed EXM 3.4 update 1 on clean Sitecore 8.2 update 2 instance. After completion of post installation steps I am getting below exceptions in log files.

As mentioned in the installation guide on the download page in step 3 of the installation process:

In the App_Config/ConnectionStrings.config file of your Sitecore solution, update the exm.master and the exm.web SQL server connection strings. For example:

<add name="exm.master" connectionString="user id=user;password=password;Data
Source=(server);Database=Sitecore_EXM" />
<add name="exm.web" connectionString="user id=user;password=password;Data

Please note that these are just example connection strings, and that you will have to change the user id, password and database name to match your setup.

    Even adding these connection string will not help. We also need to rename the databases as default sitecore databases for EXM are attached as Sitecore81_EXM Sitecore81_EXM_Web instead of Sitecore_EXM and Sitecore_EXM.WEB Apr 4, 2017 at 3:11

  • I agree however if someone dumb like me, now he might get help from this question. ;) Apr 5, 2017 at 0:37
  • Fair enough :) I added a note to clarify Apr 5, 2017 at 7:28
  • And I have marked it as Answer! Apr 5, 2017 at 23:26

This is because when you attached Sitecore Sitecore_EXM and Sitecore_EXM_WEB databases in SQL Server. They get attached as Sitecore81_EXM and Sitecore81_EXM_WEB, so database names in connection string config and attached databases is mismatched. Either Rename your exm databases in config file to match exactly same as attached dbs in SQL server or rename SQL server dbs to match exactly same as per config file to fix this issue. Hope this helps!
