Find all users with a 'Primary SMTP address' that ends with '@example.com'

Question

We have some groups and/or users that have the wrong Primary SMTP address.

1. Find all users with primary uppercase SMTP address of *@example.com while not including lowercase addresses.

2. Result should display users Name and Primary Email Address

Tried:

Get-Mailbox -Filter {recipienttypedetails -eq "SharedMailbox"} -ResultSize Unlimited |
    where-Object {($_.PrimarySMTPAddress -like "*@example.com")} |
    fl displayname,PrimarySMTPAddress

But this returns Users that have "No" uppercase SMTP address. I am looking for users and groups that have the wrong SMTP address but have a correct smtp address. The SMTP addresses need to be corrected.

Answer 1

What you are after is the Get-CASMailbox cmdlet. The Get-Mailbox cmdlet would work as well. They both have an overlap on some commands but CASMailbox is more for configuring ActiveSync and OWA.

Get-CASMailbox -ResultSize unlimited | 
where {$_.primarysmtpaddress -like "*@example.com.au"} | 
select name, primarysmtpaddress | 
Export-CSV C:\temp\file.csv

This should get you to where you need. Filter the data as required

Answer 2

The following seems to be working for me.

Thank you everyone for the help and education.

Sometimes it just takes a little help to find the right track.

Get-Mailbox -ResultSize Unlimited | where-Object {($_.PrimarySMTPAddress -like "*@somecompany.com")} | fl displayname,PrimarySMTPAddress
