More than 5,000 organisations now run Cloud Drive Mapper

Published 9 November 2026 · by Leon Mallett

Cloud Drive Mapper is now used by more than 5,000 organisations, 5,105 at the last count, with more than 1.5 million users between them and more than 600 IT and MSP partners around the world. It follows another milestone we never quite got round to sharing: 2025 was the first year IAM Cloud passed £5 million in annual recurring revenue, finishing the year at £5.26 million.

To everyone behind those numbers, our customers, our partners, and our team across Europe: thank you. And to mark the moment, we're releasing one of the biggest features in Cloud Drive Mapper's history.

Introducing Dynamic: Custom

From today, you can build your own drives in Iris. A Dynamic: Custom drive brings content from across Microsoft 365 together behind a single drive letter, so instead of handing people a row of drive letters, you give them one drive with exactly what they need.

Each Dynamic: Custom drive can hold up to 304 items:

• up to 100 SharePoint sites;
• up to 100 SharePoint document libraries;
• up to 100 shared OneDrives, colleagues' OneDrives that they've shared with the user;
• the user's own OneDrive;
• Dynamic: Teams, the Teams they belong to;
• Dynamic: SharePoint, the SharePoint sites they belong to;
• Dynamic: Shortcuts, the shortcuts they've added to their OneDrive.

And you're not limited to one. You can create as many Dynamic: Custom drives as there are free drive letters in Windows.

What makes it dynamic

A Dynamic: Custom drive isn't a fixed list of folders. Each one is built from several sources, and then personalised to every user based on their own permissions and their Teams and site memberships.

That means you can define one drive for a whole department or organisation, and each person sees only what's relevant to them and what they're allowed to open. When someone joins a Team or gets access to a new site, it appears in their drive. When they leave, it goes.

You choose how often drives refresh. The default is every six hours, because permission lookups are expensive calls to Microsoft Graph, and a conservative schedule keeps you well clear of Microsoft's throttling. Some customers refresh every 20 minutes or less, and it works well for them.

What you can do with it

Dynamic: Custom gives you complete control over what's in a drive, and just as importantly, what's out of it.

• Recreate a hub. Bring a SharePoint hub and all of its associated sites together as one drive.
• One drive per project. Give a project team its site, its document libraries, and everything else it needs behind one drive letter.
• One drive per department or business unit. Gather every site a team works across in one place.
• A single point of access. Build one drive with everything a person needs, rather than a long row of drive letters.
• Leave out what you don't need. A Dynamic: SharePoint drive shows every site someone belongs to. A Dynamic: Custom drive lets you choose exactly which ones appear, and filter out the rest.

Who can use it

Dynamic: Custom is included for every Cloud Drive Mapper customer, with no extra licence. Iris admins create and manage the drives, and that includes partners who manage customers through Central Command.

It works with Cloud Drive Mapper 3.21 and later, so nearly every customer can start using it straight away, without upgrading.

It's a good illustration of what Cloud Drive Mapper has always been about: Microsoft 365 storage, arranged the way your organisation actually works. We can't wait to see what you build with it.
