Shared mailbox with the same email (local part) can't be created to a different domain
Moi Matti,
The problem is that when you create a shared mailbox, the alias with the local name is also created. Thus, regardless of the domain part, you have the error you described.
Luckily the workaround is quite simple. Just create a shared mailbox with unique local name, such as support_domain2@domain2.com. After it is created, edit the mailbox email addresses to change the default address to support@domain2.com and you're done!
Hi!
Please see this blogpost:
I have no idea how to replicate the solution in office 365 admin center.
Simply use PowerShell, the UI is limited for this scenario.
- Without Powershell experience in a mac environment with instructions from a 5 year old blog post doesn't seem like a great combo.
This scenario seems so obvious that there must be an easier way?
Its two domains having an email address for support. Shouldn't be that complicated.ok! i've managed to create 3 shared mailboxes with the addresses of support@domain1.com , support@domain2.com and support@domain3.com. My setup was exchange online only and i did it from the exchange admin center only.
Go to exchange online admin center -> recipients -> shared : click the plus sign
Here you can type the name and also alias if you click the "more options" button..(see attached file)
Type a name and alias different to the mailaddress, like support_uk or something and set the mailaddress to ex. support@domain1.com!
Repeat this when creating another shared mailbox:
name/alias: support_us
mailaddress: support@domain2.com
tested and confirmed working in my test environment
