We have a client wit a couple of Exchange 2013 databases that have been automatically excluded from provisioning because of a lack of space.
Unfortunately I have been unable to find the minimal amount of required free space. Does anyone know the minimum amount of free space required? The disks containing the affected databases all have around 10% of free disk space at the moment.
That parameter is not applicable in environments with Exchange Installed On-premise.
That is a Microsoft Internal Parameter which they will use for managing Tenants using Microsoft Cloud services.
This parameter is reserved for internal Microsoft use.
Can you ping the output of the cmd below which is run against 1 or 2 DB's against which we have space constraints ?
Get-MailboxDatabase DatabaseName -Status | fl Name,DatabaseSize,AvailableNewMailboxSpace
AvailableNewMailboxSpace is the property which will give the information about the Freespace which can be fragmented or reclaimed after the DB is Defragmented. But Defrag on DB's on Exchange 2010 Later versions is not recommended. So, you could consider creating a new DB and move the mailboxes over to the NEW DB.

Base on my experience, there're lots of factors which relate to disk quota, for example: database copy, number of mailbox, mailbox size, the mount of message per day, the average size of message for inbound and outbound and log file.
By default, the value of IsExcludedFromProvisioning is false, also IsExcludedFromProvisioningBySpaceMonitor is True. If server disk monitor that there's no sufficient free disk space, IsExcludedFromProvisioning will be automatically set to True.
Therefore, to fix your issue, it's recommend to increase your driver disk or split those database into separate disk, for example add 200G per disk driver.

Every database has it's own disk.
We have 4 volumes all between 300 and 400 GB with 1 database per volume. Every volume has 6 to 13% of free disk space.
Adding space to the disks seems logical to me, I had the same idea. The client however pays per GB of storage so we need to explain to them why they would need the additional space. Is there any source we can quote what the minimum amount of free space needs to be?
