#MICROSOFT ACTIVESYNC TESTER UPDATE#

Over the years, connectivity has become smoother as customers upgraded to Exchange 2016 CU3 or later (always upgrade to the latest cumulative update to avoid problems like last year’s Hafnium debacle).

Microsoft documents what how Teams and Exchange interact and issues that occur between Teams and Exchange Server. However, as we know, many on-premises Exchange servers still host mailboxes, and given the success of Teams, it’s likely that millions of Teams users have on-premises mailboxes. Teams works best when it interacts with an Exchange Online mailbox. The latest tests, revealed in a Microsoft technical community post of March 3, analyze the connections between Teams and an Exchange hybrid environment. It has a new lease of life and backing within Microsoft that has allowed its developers to create new tests to help Microsoft 365 tenant administrators figure out when connectivity goes wrong. Debugging Teams and Exchange Hybridĭespite the five year hiatus, the good news is that MRCA is better than ever before. Those plans and other ideas for enhancements foundered due to a lack of investment and engineering availability. However, Microsoft dropped some hints that they wanted to incorporate connectivity tests for other applications than Exchange. In 2011, Microsoft updated ExRCA to support Office 365, but its focus remained firmly fixed on Exchange (the URL at the time was ). ExRCA was very popular and boasted its own Twitter account and YouTube video (a real trip into the past). At the time, Exchange server handled protocols like Exchange ActiveSync (mobile), Exchange Web Services, Outlook Anywhere (RPC over HTTP), and SMTP, with tests later appearing for POP3 and IMAP4. The history of RCA is that it started in 2009 as the Exchange Remote Connectivity Analyzer (ExRCA), a utility program to help Microsoft support and Exchange administrators debug connectivity problems. RCA was not in good shape and not much happened between October 2015 and January 2020. No Microsoft engineering group wanted to take responsibility for its development and maintenance, and issues like expiring certificates occurred all the time. For many years, the Microsoft Remote Connectivity Analyzer (MRCA) was in the doldrums.
