Knowledgebase

SpaceObServer runs fully on prem, but it can scan cloud storage, e.g. SharePoint Online, S3, Azure Blob. So, no agents on the scanned system are required.

The chart on our website "How SpaceObServer works" should demonstrate this:

We recommend Microsoft SQL Server 2025 Enterprise with at least 32GB of free memory (RAM) and a CPU with 4-8 cores.

Please find the supported SQL server versions here. We also documented which database size you can expect, if there are any size limits for the database size.

You can find the Offline Installer in our customer area.

To download it, please log in with your user details and navigate to "Downloads".  During maintenance, you will find the current version there as an offline installer to download.

This error code indicates that the root certificate is not trusted on the system. We just recently updated the certificate we used to sign our applications, so it still seems to be the case that this root certificate is not yet up to date.

These certificates are usually being updated and installed online and/or along with Windows updates. These updates might be disabled manually though.

Please check for pending or available Windows updates first.

If this doesn't work, please try to download and install the updated certificates manually. They are issued from GlobalSign and should therefore be considered safe:

Root certificate https://secure.globalsign.com/cacert/codesigningrootr45.crt

Intermediate certificate https://secure.globalsign.com/cacert/gsgccr45evcodesignca2020.crt

Please ensure to install the root certificate to the correct store (root certificates). Having Windows select the store automatically, it might select the wrong store for this certificate.

To install the root certificate, proceed as follows:

1. Download the certificate. If the browser reports that the file could damage the system, confirm this message with "Keep".
   As the certificate comes from a trusted source (GlobalSign), this warning is not relevant in this case.
2. Right-click on file and select "Install certificate" in the context menu.
3. A Windows dialog opens. First select the storage location "Local computer" and "Next".
4. On the following page, select "Save all certificates in the following location" -> Browse -> "Trusted root certification authorities" for this certificate.
5. Click on continue/next until the import process is complete.

Proceed in the same way to install the intermediate certificate, but select the "Intermediate certification authorities" folder in step 4.

To grant permissions on the respective site collections to be scanned via TreeSize/SpaceObServer, the PowerShell cmdlet Grant-PnPAzureADAppSitePermission can be used.

1.  Import-Module PnP.Powershell
2. Connect-PnPOnline (see Connect-PnPOnline | PnP PowerShell for connection flows and syntax)
3. Grant-PnPEntraIDAppSitePermission -AppId <AzureAppID> -DisplayName <AzureAppName>  -Site < SharePointSiteURL> -Permissions write

The user that is used for granting the permission must be a site collection admin of the respective site collection. The role 'Owner' is not sufficient.

For more information about the used cmdlets please see: https://pnp.github.io/powershell/cmdlets/

If a SharePoint Online site is configured to require a multi-factor authentication, the application will perform a browser based authentication. For a detailed explanation on how to set everything up, please refer to the manuals of TreeSize or SpaceObServer.

First ensure that you have the installer for the full version and your license key. Both are available within your maintenance period in our customer area.

You can now uninstall our software on your old computer and install it on your new computer. An explicit license deactivation is not necessary.

When you are using the option "Use MAPI client" in the settings under "Export > Email", you need to make sure that an email program like i.e. Outlook is installed and operational.

During your maintenance period, they are located at Downloads -> Older versions in the customer area, if you are logged in to your customer account.

You should be able to find the installation files and keys of the two last major versions there.

There are two main causes for why the values reported in theTreesize/SpaceObServer differ from the values reported in the storage metrics:

1. The storage metrics include the recycle bin of the site. The application does not yet take the recycle bin into account.
2. The storage metrics include all versions of all files stored in the library. TreeSize reports on the latest version only by default though. You can activate the option Options > General > 'Track advanced file system features' to let the application consider all versions. Please note that this may slow down the scan speed though.
