Duplicate user

Question

Hi, please, I would be very grateful if you could help me in some way to find users, aliases and distribution groups that are duplicates in my Office 365 organization, since I am trying to add several users and I am receiving duplicity errors. I have worked in Power Shell, but I can not find a way to create a script to determine duplicity.

How can I do?

Hello

A pleasure to help you.!!

Having the confirmation that you work or know how to work using the PowerShell Module, I can recommend the following commands to identify users / aliases / distribuxion groups, duplicates.

In the following script you should only substitute in the variable $ Duplicateuser = "user who wants to validate their duplicity".

$ Duplicateuser = "******@domain.com"

get-contact | where {$ _. WindowsEmailAddress -match "$ Duplicateuser"} | ft identity

get-msoluser -All | where {$ _. ProxyAddresses -match "$ Duplicateuser"} | select UserPrincipalName

Get-MsolGroup | where {$ _. ProxyAddresses -match "$ Duplicateuser"} | ft displayname, emailaddress

get-mailbox -Result unlimited | where {$ _. EmailAddresses -match "$ Duplicateuser"} | fl Name, RecipientType, EmailAddresses

get-DistributionGroup | where {$ _. EmailAddresses -match "$ Duplicateuser"} | fl Name, EmailAddresses

get-user -ResultSize Unlimited | where {$ _. WindowsEmailAddress -match "$ Duplicateuser"} | ft identity

Get-Recipient -ResultSize Unlimited | where {$ _. EmailAddresses -match "$ DuplicateUser"} | Select -Expand EmailAddresses Aliases

Get-msoluser | Where-Object {$ _. AlternateEmailAddresses -eq $ Duplicateuser}

Get-Mailbox -ResultSize unlimited | Where-Object {$ _. WindowsLiveID -eq $ Duplicateuser} | select userprincipalname, identity

I hope it is very helpful and can identify the user or user that may be duplicated in your organization.

Answer 4

Thanks for answering me so fast.

I just ran it and it really worked for me, great, it's what I wished I had tried other commands that I found on the internet, but the command that you just gave me is optimal for my work.

I'm really grateful I'll share it with my colleagues.

But I have an additional question, how can I validate duplicate users that are deleted?

Thank you so much for help me. Dayamis
