What Our Customers Say
CiraSync is the functionality Microsoft 365 should have built in.
“This software is one of those “best things since sliced bread.” We have eliminated probably 12-25 hours a month of somebody doing busywork maintaining contacts to push out to mobile devices.”
Ed H. Senior Network Administrator/ IT
Once it is set up, it flows seamlessly.
“I have used this software across multiple companies. It works well for what it does and solves the issues of having to copy contacts to users’ Outlook profiles. Once it is set up, if flows seamlessly.”
Matthew M. IT Director
CiraSync, always available information, on- or off line.
“CiraSync is our solution to mainly sync contact information to our organization’s iDevices. Rather than depending on a Global address list (which is not really fast in delivering information), CiraSync pushes information, on- or off line. We are happy customers.”
