SMTP address error

Question

I deleted a user's SMTP address using the Office365 management portal. I want to attach this address to a new shared email.

Trying to create a new email using this address is just for me

Email addresses need to be unique and this one is already being used by the pgreen.

I know it takes a propagation time to remove the address from the original recipient, but I believe this is measured in minutes rather than hours. Of course, I will be very clear in 6 hours, so now I want to know if I did anything wrong.

Check from O365 PowerShell module that the recipient's displayed address is no longer associated.

The deleted address has been removed from recipient pgreen ******@somethinggroup.com .

PS> (get-recipient pgreen).EmailAddresses    smtp:******@somethingfundraising.onmicrosoft.com
SMTP:******@somethingfundraising.com
SIP:******@somethingfundraising.com
smtp:******@somethingtm.com
smtp:******@somethingfundraising.com
smtp:******@somethinggroup.com

Send to deleted address[ ******@somethinggroup.com ]The email return cannot be delivered to pgreen was not found at something group.com

I can't think of any other way to determine if/what/where it happened. Just waiting for its situation?

Hi, @Tom1156

You have already deleted your e-mail address, but please double-check if there is a linked e-mail address.

You can use the following command to view the results. If the address exists, you'll see the relevant recipient information. If the address does not exist, no results will be returned.

Get-Recipient -Filter "EmailAddresses -eq 'smtp: ******@somethinggroup.com ' "

You can also try adding the email address as an alias for a shared mailbox. Specifically, after you create a shared mailbox, add ******@somethinggroup.com as an alias, then set it as your primary address and delete the old address.

It should be noted that the time for the configuration modification to take effect is affected by the configuration of the system or organization, and the specific time may be slightly extended.
