Look for Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.3 6.5.8 in the list, click on it and then click Uninstall to initiate the uninstallation. Method 2: Uninstall Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.3 6.5.8 with its uninstaller.exe. Collaboration Data Objects (CDO), previously known as OLE Messaging or Active Messaging, is an application programming interface included with Microsoft Windows and Microsoft Exchange Server products. The library allows developers to access the Global Address List and other server objects, in addition to the contents of mailboxes and public folders.
I wanted to point out a significant note for some in the Exchange 2016 Architecture blog post here : http://blogs.technet.com/b/exchange/archive/2015/05/05/exchange-server-2016-architecture.aspx. Specifically, that Exchange 2016 will not support clients using Exchange's MAPI (aka MAPI CDO) to access Exchange Data. Exchange's MAPI has been out of main stream support for some time now (as it's tied to the lifecycle of Exchange 2003), so it isn't a surprise that Exchange 2016 will no longer allow it. However, for some ISVs and vendors still relying on MAPI CDO this is important note. The time to start planning and developing the next version of your product is now so you are ready when Exchange 2016 ships.

Cause
Acronis Backup works with Exchange mailboxes by using Microsoft Exchange MAPI and CDO. Microsoft Outlook substitutes some of the Microsoft Exchange MAPI and CDO files on the Exchange server with its own version of MAPI and CDO. This corrupts Microsoft Exchange MAPI and CDO and prevents Acronis Backup from correct work with Exchange mailboxes.
Solution
Perform the following steps on the Exchange server where Microsoft Outlook is detected:
