Enterprise Coexistence Collaboration Tool

Enterprise Coexistence During Mergers, Acquisitions or Divestitures

We allow end-users to collaborate as if they’re on the same system during mergers, acquisitions, or divestitures. A great way to enhance communications between different platforms with no impact on day-to-day operations.

Whether you’re looking for a seamless, short-term tool during mail migration or a reliable long-term solution for users on multiple environments, the Cloudiway coexistence suite provides everything you need.

Take away the configuration headache of coexistence with Cloudiway. Our 2 main components are Calendar Free/Busy, and GALSync. Share free/busy time between users on different platforms, use the GALSync directory sync tool to synchronize your Office 365 global address lists. Each can be purchased individually and work with any combination of Office 365, Exchange On-premises, and Google Workspace.

Your address books remain synchronized during migration, as well as your user passwords, groups, etc. You can migrate your users in batches. Using Cloudiway migration, you will be able to provision and migrate the users in each batch at a time and date of your choice.
