Hi,

Following are the reason why MSN is not allowing you to send and receive emails:

If your data base of your email is corrupt it will load slowly and sometime automatically MSN will shut down. If you have an Antivirus software, or a firewall which might be blocking the msn to reply emails.

If your MSN is corrupt it will fail to respond.

In order to fix this you need to rename the SDF files which are in Database folder.

To find the database folder location, please follow the instruction given below:

Windows Vista/Windows 7/Windows 8.1/Windows 10

Note: Sign out from MSN then close the program before performing the steps below.

1.  Click ‘Start’

          2. In the Search box, type the following: %USERPROFILE%\AppData\Local\Microsoft\MSN

          3. Press the ENTER key         

          The MSN folder will open.

          4. In the MSN folder, do the following:     

               a. Click ‘Organize’, ‘Folder and Search options’, then ‘View’

               b. Put a dot on ‘Show hidden files and folders’

               c. Uncheck the ‘Hide extensions for known file types’ and ‘Hide protected operating system files options’

               d. Click ‘Apply’, then ‘OK’

       If Its msn 11.00/11.50 db30 and db40 folders will appear inside the MSN folder.

          5. Open db40(msn11.00/ 11.50)folder then look for files that end as msn-com.sdf and msn-com_JMF.sdf

          6. Right-click, choose ‘Rename’ and add .old after .sdf to both these files

          7. Close the db40 folder

Open the db40(msn10.50)folder then look for files that end as msn-com.sdf and msn-com_JMF.sdf
 Right-click, choose ‘Rename’ and add .old after .sdf to both these files
      
. Close the db40 folder

After renaming the sdf files. Sign in to MSN and wait for the emails to get filter.If still you are unable to reply emails on msn client, then please check the private message for further assistance
