A customer is right now migrating from a Thirdparty MDM solution to Microsoft Intune. He has a custom iOS IMAP configuration for round about 30 users and do not wanted them to migrate every policy manually so we created a quick Powershell script which is changing the user values inside the XML and uploads them as a configuration via the Intune Graph API.
The interesting part was, that these are Exchange Online Shared mailboxes which have to be configured with the primary user’s UPN account.
So I have taken the DeviceConfiguration_Add.ps1 Powershell Script from the Intune Github Sample Page and added/changed the following things.
The full script is available as a GIST or on the bottom of the blog post.
- Added a parameter named $upn which is getting the User Principal Name for which user the policy should be built. Line 14-17
1234param ([Parameter(Mandatory=$True)][string]$upn)
- Added a region called “Build XML” where I am replacing some Usernames with variables. Line 320 – 408
123456789101112131415161718192021222324252627282930313233343536373839404142434445464748#Split out the surname of the upn$name = ($upn.Split('.')[1]).Split('@')[0]#Split out the first letter of the name$conUsername = ($upn.Substring(0,1) + '.' + $name)#Building the custom XML payload with the variables $name and $conUsername$xmlPayload = @"<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict><key>PayloadContent</key><array><dict><key>EmailAccountDescription</key><string>Contoso Confidential</string><key>EmailAccountName</key><string>Confidential</string><key>EmailAccountType</key><string>EmailTypeIMAP</string><key>EmailAddress</key><string>$conUsername@contoso.com</string><key>IncomingMailServerAuthentication</key><string>EmailAuthPassword</string><key>IncomingMailServerHostName</key><string>outlook.office365.com</string><key>IncomingMailServerPortNumber</key><integer>993</integer><key>IncomingMailServerUseSSL</key><true/><key>IncomingMailServerUsername</key><string>$upn\$conUsername</string><key>OutgoingMailServerAuthentication</key><string>EmailAuthPassword</string><key>OutgoingMailServerHostName</key><string>smtp.office365.com</string><key>OutgoingMailServerPortNumber</key><integer>587</integer><key>OutgoingMailServerUseSSL</key><true/><key>OutgoingMailServerUsername</key><string>$upn</string><key>OutgoingPasswordSameAsIncomingPassword</key><false/><key>PayloadDescription</key><string>Configures Email settings</string><key>PayloadDisplayName</key><string>Contoso Confidential</string> - Finally a region called “Build JSON Payload” where I encoding the UTF8 XML Payload to a BASE64 string and building the JSON request. Line 410 – 425
123456789101112$bytes = [System.Text.Encoding]::UTF8.GetBytes($xmlPayload)$encodedPayload =[Convert]::ToBase64String($bytes)$jsonConfig = @"{"@odata.type": "#microsoft.graph.iosCustomConfiguration","displayName": "iOS - Confidential $name","payloadName": "Confidential - $conUsername","payloadFileName": "config.xml","payload": "$encodedPayload"}"@
This is my first public Powershell script, so if there are any requests to make it portable and do some error checks I am happy about your feedback.
And here is the full script.
