MAILBOXES NOT FOUNDED

Question

MAILBOXES NOT FOUNDED

Antonio 1

Hi,
from the exchange admin panel I can't see the mailboxes belonging to 2 users provided with an active 365 business basic licence.
The same two are shown regularly in the Microsoft 365 admin panel.
Thank you for the assistance.
Best regards

Hi @Antonio ,
Please have a ask if the two users who don't appear in the EAC were created directly from the Microsoft 365 admin panel? Or were they migrated from on-prem exchange?
Have you check if they are in the contact page?

Please refer to the following command to get more detail about the mailbox:

GET-EXOmailbox -identity <username>

(Note: Please pay attention to protecting the privacy information in your post. Thank you!)

Hi @Aholic Liang-MSFT ,
thanks. They were both created directly from the Microsoft 365 Admin panel and they are not in the contact page.
If I try to edit the mail Exchange properties from the 365 Admin Center I get the following error:
"The operation couldn't be performed because object '_cff14ffc60' couldn't be found on '.prod.outlook.com'".

Hi @Aholic Liang-MSFT ,
please don't mind a common question: what should I use to launch the suggested command [GET-EXOmailbox -identity <username>] ?
Thanks

Hi,
It has been a few days and I am checking in to see how things are going on with this issue. Do you perhaps have any further concerns or questions?

Hi @Aholic Liang-MSFT ,
the two mailboxes were apparently linked to MS Bookings and that caused the issue.
We were advised to create them again through exchange.
Thanks for the assistance.
