Clean Up AD Attributes for an O365 Migration with PowerShell

I recently had to perform an Office 365 migration for a client with hundreds of users / mailboxes with a terrible assortment of mismatched on-premises Active Directory attributes.

The script below is a script I spent quite a while writing that will fully clean up AD attributes and prepare your users for migration to Office 365 from on-prem Exchange.

The script can be downloaded below, and I’ve posted the raw code as well for review:

<# 
.SYNOPSIS 
 CleanUpADAttributesforO365.ps1 - Cleanly formats AD attributes for a migration to Office 365
 
.DESCRIPTION 
 This powershell script fully cleans up the following attributes and prepares users to be synced
 to Office 365 using Microsoft AD Connect:
 
 ♦Attribute: SamAccountName
		○ Converts the current user SamAccountName attribute to lower case. No other modifications
		  are made to this attribute.
 ♦Attribute: mail
		○ Converts the current user mail attribute to lower case. No other modifications
		  are made to this attribute.
 ♦Attribute: mailNickname
		○ Converts the current user mailNickname attribute to lower case. No other modifications
		  are made to this attribute.
 ♦Attribute: UserPrincipalName
		○ Converts the current user UserPrincipalName attribute to lower case and changes the UPN
 ♦Attribute: proxyAddresses
		○ Converts all of the current user proxyAddresses to lower case and adds an additional
		  proxyAddress for the new Office 365 .onmicrosoft.com URL, using their primary email alias
		  as the alias for the .onmicrosoft.com new proxyAddress

.SYNOPSIS

CleanUpADAttributesforO365.ps1 - Cleanly formats AD attributes for a migration to Office 365

.DESCRIPTION

This powershell script fully cleans up the following attributes and prepares users to be synced

to Office 365 using Microsoft AD Connect:

♦Attribute: SamAccountName

○ Converts the current user SamAccountName attribute to lower case. No other modifications

are made to this attribute.

♦Attribute: mail

○ Converts the current user mail attribute to lower case. No other modifications

are made to this attribute.

♦Attribute: mailNickname

○ Converts the current user mailNickname attribute to lower case. No other modifications

are made to this attribute.

♦Attribute: UserPrincipalName

○ Converts the current user UserPrincipalName attribute to lower case and changes the UPN

♦Attribute: proxyAddresses

○ Converts all of the current user proxyAddresses to lower case and adds an additional

proxyAddress for the new Office 365 .onmicrosoft.com URL, using their primary email alias

as the alias for the .onmicrosoft.com new proxyAddress

#################################################################################################

│ SWITCHES │

│ Review the 12 switches below and set them to true or false based on your needs. │

│ Note: The bottom two switches cannot both be set to True (for the mail attribute), │

│ pick only one. │

#Switches for adding new domains / proxyAddresses. These can all be set to true:

#Add your O365 tenant domains to your on-premis AD domain as additional UPN suffixes - recommended:

$addO365DomainstoUPNSuffixesforAD = $true

#Set the switch below to true if you want to add a new proxy address for the .onmicrosoft.com domain of your O365 tenant:

$addNewProxyAddressesForO365Tenant = $true

###Switches for converting variables to lower-case. These can all be set to true:###

#Set the switch below to true if you want to convert all proxyAddresses to lower-case:

$convertProxyAddressestoLowerCase = $true

#Set the switch below to true if you want to convert their mailNickname attribute to lower case:

$convertMailNicknametoLowerCase = $true

#Set the switch below to true if you want to convert their SamAccountName attribute to lower case:

$convertSamAccountNametoLowerCase = $true

#Set the switch below to true if you want to convert their UserPrincipalName attribute to lower case:

$convertUserPrincipalNametoLowerCase = $true

#Set the switch below to true if you want to convert their mail attribute to lower case:

$convertMailAttrtoLowerCase = $true

#Switches for changing existing paramaters to new values using the variables you specify in the Variables section:

#Set the switch below to true if you want to replace the user UPN with a new domain specified below:

$changeUserUPNtoNewDomain = $true

#Set the switch below if you want to change their primary SMTP address to their UserPrincipalName @ the new UPN suffix you specify below:

$changePrimaryProxyAddrToUPNatNewDomain = $true

#Set the switch below if you want to set the mail attribute for each user to match their UserPrincipalName @ The new UPN suffix you specify below:

$changeMailAttributetoUPNwithNewDomain = $true

#Set the switch below to true if you want to set their mail attribute to match their primary SMTP proxyAddress (in case it is different):

$changeMailAttributeToPrimaryProxyAddr = $false

#################################################################################################

│ VARIABLES │

│ Review the variables below and set them based on your needs. │

│ Note: If you change the log file paths to have spaces, you need to enclose them in quotes.│

│ │

#Set the variable below to the OU that you want to search within for selecting the users to modify:

$userOU = "OU=SCA Users,DC=sca,DC=titan,DC=1sourcing,DC=net"

#Set the variable below to the DN of the security group that you want to search within for selecting the users to modify:

$groupDN = "CN=TestGroup,CN=Users,DC=siskinspine,DC=com"

#Fill out the variable below if you want to filter a user search by users that already have a valid proxyAddress matching the domain suffix below.

$searchDomain = "siskinspine.com"

#Fill out the variable below if you would like to add a new UPN suffix to the domain / forest for changing the user UPN.

$newUPNsuffix = "siskinspine.com"

#Fill out the two variables below with your O365 tenant domains name without the @ if you chose to add a new SMTP Proxy Address in the above switches:

$newO365TenantDomain = "siskinspine.onmicrosoft.com"

$secondNewO365TenantDomain = "mail.siskinspine.onmicrosoft.com"

#Set the variable below to the location for the master log file:

$masterLogFile = "C:\temp\ADCleanupMasterLog.log"

#Set the variable below to the location for the log file containing the unmodified settings for each user before we change them:

$usersBeforeChangeLogFile = "C:\temp\UsersBeforeChange.log"

#Set the variable below to the location for the log file containing the "after" version of the settings for each user to compare with the before file:

$usersAfterChangeLogFile = "C:\temp\UsersAfterChange.log"

#################################################################################################

│ Search OU │

│ Use the uncommented line below if you want to search by group. │

│ If you want to search by user OU, comment the first line and uncomment the second line │

│ Alternatively, if you want to filter a users search by users that already have an │

│ existingproxyAddress that matches a given domain, comment the first two lines and │

│ uncomment the third line, making sure you filled out the $searchDomain variable. │

│ You do not need to fill out the $userOU or $groupDN variables when using the third line. │
