Powershell script for Office365 Federation

This script helps you

• To add a new domain and federate with your on-premise ADFS server.
• To federate your existing Office365 domain.  

Requirement

• You need to run this script from the ADFS box which will federate with Office365.
• Basic idea of how to add a TXT entry to your hosting provider, for more info refer https://onlinehelp.microsoft.com/en-us/office365-enterprises/gg584188.aspx .

Quick introduction about this guy.

He collects the following information from you:

• Office365 credentials
• Domain Name
• Your confirmation to know: if you are federating with a domain name which is already added to your Office365 portal or add and federate a new domain to office365.
• Finaly a log file location for an error output.

Things you should be aware:-

• This script does the domain verification, once the added TXT record is replicated.
• Domains added using this script can be verified only with New-MsolFederatedDomain –DomainName <Domain Name> command
• The domain verification might fail due to TXT recort replication, if so follow this KB Article and run New-MsolFederatedDomain –DomainName <Domain Name>

 Note: - With my experience, I had to wait for 15-30 mins for the DNS replication.

I recommend you to download the attached .ps1 file to avoid any typo's.

• Choose your option, if you need to federate an existing domain / add & federate a new Domain
• Based on your selection the script federate / add & federate a domain to Office365
  • If it is only the federation of an existing Domain, then this script does the federation and ends there.
  • If it is for adding & federating a new domain to Office365 then it follow the below steps:
    • Adds the domain to your Office365 tenant
    • Provides the TXT record that needs to be added with your provider
    • Once the record is added and ready for replication, An ENTER key will help the script to verify your domain.
    • If the verification failed for the 1^st time, it prompts you to validate the replication of TXT record that was added and then confirm by hitting an ENTER key.
    • If the TXT record was replicated, your verification will be completed by now.
    • Else, you will have to run New-MsolFederatedDomain -DomainName <Domain Name> for verifying the domain once the TXT record replication is done.
• Once the script is executed set it back to Restricted, using

Hope this helps you.
