set-place command populating room mailboxes (floor and capacity) with value 0 when it should be empty

If the Set-Place cmdlet is operating on an AD object directly and not on the mailbox (and then depending on Exchange to modify the AD object), you might try using the Set-ADObject cmdlet and the -Clear parameter to remove the value.

I think the -Clear parameter takes the LDAP name of the property, which may very well be different to the name of the value in the Set-Place cmdlet.

I have no Exchange server on which to try this, so the above is just my best guess at a solution!

Hi @MasterBlaster

I tested in my lab but was not able to set the values of the parameters (floor and capacity) back to the default None value.

If using $null as the value to the parameters, it would not return any errors but the actual value remains unchanged.
I am afraid it may be the by-designed behavior that you must input an integer as a valid value.

I suppose if you are using a csv file to butch modify the information of room mailboxes, you may have to specific invaild values (like a string) instead of leaving it blank for these two parameters.
It would fail to change the values of the two parameters and return error messages.

Hello Harshit,

Set-Place, This cmdlet is available only in the cloud-based service.

Use the Set-Place cmdlet to update room mailboxes with additional metadata, which provides a better search and room suggestion experience.

In hybrid environments, this cmdlet doesn't work on the following properties on synchronized room mailboxes: City, CountryOrRegion, GeoCoordinates, Phone, PostalCode, State, and Street. To modify these properties on synchronized room mailboxes, use the Set-User or Set-Mailbox cmdlets in on-premises Exchange.

Hope this answers all your queries, if not please do repost back.

Hello, dear Microsoft,

Is there any update on that topic? How can we reset the floor value to its default setting (empty)? Any answer that helps solve this will be appreciated.

Best regards
