How to setup room accounts

ozy

Hello,

I'm struggling to get rooms to work properly, and I asked myself is there was any "special" way to deal with that.

First off, I come from an Exchange environment, and never had to deal with "normal" or "shared" room accounts.
Is that the equivalent of setting up a standard room mailbox with -EnableRoomMailboxAccount $true -RoomMailboxPassword (Get-Credential).password parameters ?
Is there perhaps any (important) difference between normal and shared rooms apart from the normal one being basically a full blown mailbox ?

So I begun setting up a shared room account in Grommunio admin UI.
I checked both decline meetings with secheduling conflicts and accept conflict-free metings as in the following screenshot.

So far, when I try to include the room in a new meeting, the room doesn't get booked.
Anyway, I am not allowed to see the room calendar unless I change the default / anonymous permissions.

Here's where it gets tricky for me.
I can change permissions via grommunio-admin for specific users, eg grommunio-admin exmdb room@domain.tld folder grant 0xf user@domain.tld 0x061b, but I can't do so for anonmyous / default permssions, at least I didn't find any way to achieve this per CLI.
So in the meantime, I did make myself "owner" of the shared room mailbox, changed the permissions to "author" for both anonymous / default entries, then removed myself from the owner permissions again.

Now, when I create a new meeting request, once I'm not the "owner" anymore, the meetings don't show up in shared room calendar.

I cannot imagine that the whole Grommunio rooms don't work.
Is there something I basically did very wrong ?

Is there any guide on how to setups rooms ? Documentation is quite thin for this AFAIK.
Anyone successfully deployed rooms / equipment mailboxes ?

Thanks for any better insight, it's been days and I get crazy.

Currently running gromox-2.48.161.gcc55a07-lp156.91.1.x86_64

Some notes, if I happen to set permissions via grommunio-web, "read items" don't stay.
If I happen to add same permissions via Outlook, permissions stay.
If using outlook cached mode, I need to disable "download shared folders" in order for shared calendars to show up properly.

So far no entries show up in rooms, shared (or normal btw) when I setup new meetings and include the room.
I need to use the "one step" rule processor since the "two step" rule processor disables forwards etc for now, so I guess somehow meetings don't get accepted by the calendar ?
Any workaround perhaps ?

Btw, does the "room address book" exist or is it normals that rooms show up in GAB ?

Honestly, I'm quite a seasoned Exchange admin, and use Grommunio for about 2 years now (never used the room features), but here I'm totally lost, and nothing really makes sense.

There must be something stupid I do. Any help would be appreciated.
