Microsoft Exchange - OVH Hosted


OVH offers a professional email hosting service called OVH Exchange, based on Microsoft Exchange technology. This service enables businesses to efficiently manage their emails, calendars, and contacts with seamless integration with Outlook and other email clients. It is compatible with ROOMZ, making it easier to integrate meeting room management solutions with this email platform.

Create a ROOMZ User

Communication with calendars will be done through delegation using a user account. Therefore, we recommend creating a specific user account named Roomz. This account does not require a license or administrative rights.


If you haven't done so already, first you need to create the resources (meeting rooms):

  1. Log in to your OVHcloud customer space and select Web Cloud from the top navigation bar.

  2. Click on Microsoft, then select Exchange. Choose the relevant Exchange service.

  3. Click on the Plus + tab, then select Resources.



Click on the "Add a resource account" button to create your first resource. In the new window, fill in the following fields:


Resource email address

Enter the resource's email address

Resource name

Enter the Resource name


You can define the maximum size of a resource (for example, the number of seats in a room or shared company vehicle seats).

Allow conflicts

If this box is checked, you will be able to create overlapping calendar events involving the same resource.

Resource type


Click on "Next" to proceed to the summary, then confirm the task by clicking on "Create."

Access rights & calendar information


In the resource section, click on the three dots of the desired meeting room and select "Manage delegations”.

In the permissions, you need to select the account you created in step and check all the boxes for that account:

You can repeat these actions for the other rooms that the account needs access to for ROOMZ.


Meeting Title & Private Flag


By default, when a user is sending an invitation for reserving a meeting room, Exchange will only store the name of the organizer in the agenda of the meeting room. The meeting's title and the private flag are not stored.

With OVH, you may not have direct access to the console, so you will need to contact OVH directly for the command to be entered by their support


If you want to show the meeting title, the following PowerShell command has to be executed for each room. When the meeting is considered as 'private', the title of the meeting will be replaced by 'Reserved' on the ROOMZ Display. 

(Adapt the parameter "" to the email address of the desired meeting room)

Set-CalendarProcessing -Identity ""-AddOrganizerToSubject $false -DeleteSubject $false -RemovePrivateProperty $false

The following command allows applying the parameter to all rooms :

Get-Mailbox| where {$_.RecipientTypeDetails -eq "RoomMailbox"} | Set-CalendarProcessing -AddOrganizerToSubject $false -DeleteSubject $false -RemovePrivateProperty $false

Once executed, this command will only be effective for the new meetings. When new meeting rooms are created, this command has to be executed again.
Make sure to activate “Show meetings titles” in the Room option set menu. From default, the titles are deactivated:
