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

    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 !
