Is your sync software vendor closing its doors or no longer supporting new platforms? Connected Software announced earlier this year that they are winding down operations and shutting down September 30, 2022. For affordable Epicenter Server GAL sync alternatives and a replacement solution you can count on, let DidItBetter Software help — ask about Add2Exchange for up to date corporate contacts on employees’ phones from the GAL or from an Exchange Public Folder containing contacts or calendar appointments!

Nothing to install on each individual smartphone, mobile device, or on user workstations (or their virtual machines) – one installation, centrally-managed that works in the background seamlessly. 

Looking for an Exchange sync software vendor supporting the newest platforms? If using CODETWO’s Exchange Sync software which only supports Exchange 2013 (and prior versions) at this time, you might be looking for another Exchange public folder sync app. With organizations migrating to Exchange 2019, 2016, Office 365, we can help. Our Add2Exchange app is timeless … and works with many different platforms (Exchange 2019, 2016 (and prior), hosted Exchange, Microsoft 365 (Office 365) / Exchange Online, hosted Exchange, M365 hybrid, and also supports cross tenant GAL and calendar sync).  Hosted Add2Exchange options available!

Thanks for the support you gave me in migrating the Add2Exchange product to my new server environment…it was a bit more involved than I originally planned, but your technical support helped me through this to make sure my transition was complete. Excellent job! And I for one am very happy to have this project off my desk.
