To make it easier for you to deploy, we use stored “Credentials” in our PowerShell Scripts.

The following list should help you see the “Credentials” we are using.


 NameVariable for CredVariable for FileFilename
SMTP Credentials$SMTPcredential$SMTPcredential_FileSMTPCreds.xml

Azure Graph API$AzureADGraphAPICred$AzureADGraphAPICred_FileAzureADCreds.xml
Mail Graph API$AzureGraphMailCred$AzureGraphMailCred_FileAzureGraphMailCreds.xml

Run the following PowerShell command to store credentials in an XML File. Make sure you run the command as the Service User, configured at the IIS App Pool. Change the Path to fit your Credentials Store.
