Express Not Working after Upgrade to MailSite v6 The MailSite Express service fails after upgrading from 5.3.4 or below MailSite v6 has a new installation which introduces a new MailSite user account. In version 5 the default MailSIte services account was called MailSite-user; this user has been replaced by MSIISUSR. The new account has no permissions set other than local system access and is a member of the user group.

You will need to modify the settings so that Either MSIISUSR has rights to the mailsite and express directories and access to the BOX directory or your existing user account has the correct access.

SECURITY settings for MailSite version 6

Folder	                      User/Group	        Permission	
\MailSite	              SYSTEM	                Full Control
\MailSite	              Administrators	        Full Control
\MailSite	              MSIISUSER	                Modify	
\MailSite\Express\Web\Cache   [IWAM_MACHINE-NAME]	Modify	

In addition to the settings below, be sure that you have done the following if MailSite express is not properly operational:

• Reset the USER account you have used to access mailsite express via IIS management console, for example MailSite-user
• Restarted the IIS service after re-setting the account
• Made sure that MSIISUSER has access to the MailSite directory and child directories - if using the new account
• Make sure the BOX directory has permissions to be accessed by the account you have set up or the new MSIISUSER account

If you are upgrading a clustered solution, you will have to assign the user you had previously installed to the version 6 services and to the MailSite Express virtual directory.
