About 6 hours ago I removed an SMTP address from one of our users using the Office365 admin portal. I want to attach this address to a new shared mailbox.
Trying to create the new mailbox with the address is just giving me
Email addresses need to be unique and this one is already being used by the pgreen.
I understand that there is a time period for the removal of the address from the original recipient to propagate but I thought that was measured in minutes, not hours. Certainly after 6 hours I'd expect it to be clear, so now I'm wondering if I've done something wrong.
Checking the recipient from the O365 powershell module show the address is no longer associated.
The address removed was email@example.com from the recipient pgreen.
PS> (get-recipient pgreen).EmailAddresses smtp:firstname.lastname@example.org SMTP:email@example.com SIP:firstname.lastname@example.org smtp:email@example.com smtp:Pfullname.Green@somethingfundraising.com smtp:Pfullname.Green@somethinggroup.com
Email sent to the removed address [firstname.lastname@example.org] is returned undeliverable
pgreen wasn't found at somethinggroup.com
I can't think of any other way to identify if/what/where is going on. Is it just a case of waiting it out?
