February 25, 2017 Leave a comment

a few days ago I got the project to implement migration from google to o365 incude mailbox and onedrive online, we have done migration data mailbox using third party, but this post i dont want to discuss how to migration the data from google to o365 but I want to share step by step to migration the users using scripting while users will be moved to o365

just for information we have to change the domain from @demagnum.com to @demagnum.co.id

  1. Create forwarding users in gmail to forward users o365, here i dont have script to enable forwarding in gmail because i dont have experience in gmail
  2. Remove-MailContact -Identity “deby@demagnum.co.id” -confirm:$false previously we create all contact in gmail because for this implementation we didnt migration big bang, so we have migration for partial users,
  3. set-aduser “deby” -clear msexchhidefromaddresslists we need to clear exchange address list in proxy SMTP address because we will create new smtp proxy address will be defined
  4. Get-Aduser -identity “deby” | Set-aduser -Clear Proxyaddresses yes we need step to clear proxy addres
  5. Get-Aduser -identity “deby” | Set-aduser -add @{proxyaddresses = “SMTP:deby@demagnum.co.id”} we need add SMTP proxy address will be defined
  6. Running delta azure AD Connect, because primary address SMTP on active directory need sync to o365
  7. Set-MsolUserPrincipalName -UserPrincipalName “deby@demagnum.com” -NewUserPrincipalName “deby@demagnum.co.id” we need to change UPN existing from @demagnum.com to @demagnum.co.id
  8. Get-Aduser -identity “deby” | Set-aduser -add @{proxyaddresses = “smtp:deby@demagnum.com”}  we need add additional SMTP previously to be secondary SMTP address to o365

Office 365 PowerShell Tip: Bulk change UPN’s

February 26, 2016 2 comments

Sometimes you may provision accounts in Office 365 before any sort of domain validation.  In this case, you don’t want to hit up each user account and manually change the UPN one at a time, possibly leading to setting something incorrectly.  We’re going to give you some PowerShell code you can cut and paste to make this change.  This code will effectively:

  1. Change the domain portion of the UPN to the domain of your choice
  2. Not change the UPN of the admin account (we determine this by ignoring any UPN that begins with “admin@”).  Normally you aren’t going to change the admin account UPN to your own domain and will leave it as the onmicrosoft.com address.

Here’s a quick two line PowerShell command you can do to change all of the UPN’s in your account:

  1. Install the Office 365 PowerShell modules
  2. Launch the command shell from the start menu (Start → All Programs → Microsoft Online Services → Microsoft Online Services Module for Windows PowerShell)
  3. Copy and paste the following into the window (replace example.com with your own domain)

Connect-MsolService

Get-MsolUser -all | Where { -Not $_.UserPrincipalName.ToLower().StartsWith(“admin@”) } | ForEach { Set-MsolUserPrincipalName -ObjectId $_.ObjectId -NewUserPrincipalName ($_.UserPrincipalName.Split(“@”)[0] + “@example.com”) }

As you can see, PowerShell is a very powerfull tool to perform bulk operations.
