Migrated room mailbox in hybrid shows under mailbox instead of rooms

Question

Hi ,

i am in a full hybrid setup.
i migrated my room mailboxes to O365 and apparently all is fine except the room mailbox show under "mailboxes" in the onprem environment (as mail-enabled users)
I have read articles that say that onprem doesn't know it is a remoteroommailbox , but isn't there a solution to have those remoteroommailboxes under "rooms" and not "mailboxes" on the onprem server ?
I have checked attribute editor for the values msexchrecipienttypedetails and msexchrecipientdisplaytype and they seem correct ...

Hi @FSO1983
Totally normal and expected. Its just a visual thing, so I would not be concerned

In Power Shell, however, it should show it correctly.

Get-aduser <Migrated Room> -Properties * |FL  *rec*  

msExchRecipientDisplayType : -2147481850
msExchRecipientTypeDetails : 8589934592
msExchRemoteRecipientType : 36

and

Get-RemoteMailbox <Migrated Room>  

RecipientTypeDetails RemoteRecipientType

--------------------
-------------------
RemoteRoomMailbox Migrated, RoomMailbox

Update:
I did a test and created a remote room mailbox directly from on-prem and it still shows as a 365 Mailbox under Mailboxes in On-Prem EAC.
So its totally cosmetic and doesn't affect functionality

Answer 2

Hi ,

i just checked the settings and they are ok :

msExchRecipientDisplayType : -2147481850
msExchRecipientTypeDetails : 8589934592
msExchRemoteRecipientType : 36

the command get-remotemailbox gives me
remoteroommailbox and migrated,Roommailbox - so ok .

All settings indeed seem ok , so it will be pure cosmetic.
Thanks for this reply , very clear !
