Firstly ensure you're within your GSuite Admin panel, from there select the Apps > Marketplace Apps > CloudManager menu options. Once you're within this menu, there'll be a bin/trash icon in the tool bar at the top. If you click on this you'll get a confirmation prompt. After you've confirmed that you want to remove the app you'll be brought back to your Marketplace Apps menu screen. Please note that you may still get marketing emails, be sure to unsubscribe from these also!
Some users get domain notification emails when they've stopped using CloudManager, if this is your case please see our removal of CloudManager page, as you only receive these with an active CloudManager installation. If you've removed CloudManager but still get "marketing" emails or "update" emails about the state of CloudManager as a product, you'll find an unsubscribe link at the bottom of the email which will remove you from our CloudManager mailing list. You need to do both of these actions to not receive further emails from CloudManager.
No, CloudManager as it currently stands absolutely requires to be installed on the Primary Domain. Attempting to do otherwise can cause issues when attempting to access CloudManager or run any sync. You can only install on the Primary domain.
No, right now there is no way for CloudManager to be aware of domain name changes. However this doesn't mean it can't be done! A lot of your information in CloudManager is already influence by Google, however not all. Several steps are required in order to have a copy of your own data to be re-imported once CloudManager is reinstalled on the new domain name. Firstly you'll want to go to your Root Organisation and then from the 3-dotted menu in the top right, select export. You'll be presented with a menu item asking what format you want your file to be in, and if you want to export all the child OUs, be sure to enable this. Once you've enabled that, select the format you want and hit export. After this is done go to the External Contacts OU (if you have any) and export those too, using the same method described. It's important to note here that not everything can be saved whilst doing this - Smart Groups/Contacts will be lost, they'll just be manual items in GSuite, also any custom roles or OU rules you have in place will also be lost, you may therefore want to be sure that you go to Email Signatures, click on "Tools" and then "Source Code" and then copy all the text shown into a text file that can be copied from later back into CloudManager.
No, this cannot be done. We charge for the number of users at the point of purchase, and we take into account if your domain has more/less users at the point of renewal. However, CloudManager is used to manage all users therefore all users require a license.
