Let me give you an example of how this almost ruined a project of one of our company's customer due to this new 'UPGRADE' Microsoft released with Office 2016.Ī Customer is migrating from a Hosted Exchange email provider to Office 365 (Exchange Online) but the migration also includes to upgrade their office desktop applications. It seems that Microsoft is forcing us to use their email services trough Exchange Online if we are getting the software trough an Office ProPlus subscription or any other Office 365 plan that includes it.

Log onto Exchange ActiveSync mail server (EAS): The server cannot be found. What is the issue then? The problem occurs because Outlook does not support connections to a server that is running Exchange Server by using the EAS protocol and when you configure Microsoft Outlook to connect to Microsoft Exchange by using the Exchange ActiveSync (EAS) protocol, you receive the following error message: Having said that Exchange ActiveSync lets mobile phone users access their email, calendar, contacts, and tasks, and lets them continue to access this information when they're working offline.įor now all seems to be clear and right.

The protocol, based on HTTP and XML, lets mobile phones access an organization's information on a server that's running Microsoft Exchange. Exchange ActiveSync is an Exchange synchronization protocol that's optimized to work together with high-latency and low-bandwidth networks. Exchange ActiveSync is enabled by default when you install Exchange 2016. Let me give you some details about Exchange ActiveSync and what it does.Įxchange ActiveSync is a client protocol that lets you synchronize a mobile device with your Exchange mailbox. On a regular basis Microsoft is releasing upgrades for Office Desktop applications, most of them comes with a lot of benefits that makes things easier but some of them are just not that good.
