o ensure that you have the correct settings configured in the "import.exch.ini" file, please configure Outlook on a machine (other than the importer) connected to the same domain and network segment authenticated as the policy engine user who will be deployed with the Importer. Once configured follow the steps below:
a. Start Microsoft Outlook.
b. On the Tools menu, click Account Settings.
c. Click the E-mail tab, click the Exchange account, and then click Change.
d. Click More Settings, and then click the Connection tab.
This will display the Microsoft Exchange Proxy Settings.
The "Connection Settings" string is equal to MSExch.ProxyServerName in the .ini file.
For example; https://email.unipraxis.com
If you are using SSL then check note the FQDN that is listed in the "Only connect to proxy servers that have this principal name in their certificate" box. For example, email.unipraxis.com. This aligns with the .ini setting = "MSExch.CertPrincipal = msstd:"
The "Proxy Authentication Settings" string is equal to MSExch.HTTPAuthMethod in the .ini file.
For example; NTLM
Also add the following line to your .ini file
MSExch.IgnoreNoPublicFolders = yes
This is to avoid any additional errors relating to public folders and more detail on this setting is discussed in the Technical Document ID: TEC554432.
