Many users of Windows Live Mail 2012 have received an email under this heading from the Outlook Team advising them of the changes that are taking place at Outlook.com as accounts are migrated to the same platform as that used by Office 365. Apart from advice to switch to using the built-in Mail apps on Windows 8.1 and 10, users are instructed to apply the patch KB3093594 . A few points to note: The change means that migrated accounts can no longer be synchronized using the old DeltaSync protocol. To synchronize these accounts, users can set up the account again to use IMAP . This will enable mail messages and folders to synchronize, but not the calendar and contacts. The patch enables support for Exchange ActiveSync (EAS) to be used instead of DeltaSync in Windows Live Mail 2012 on Windows 7, 8 and 8.1 (see System requirements on the download page). Mail synchronization errors can often be cleared by removing the account, closing down the program and waiting a few minutes, then re-launching it and adding the account back again. We don't know what is going to happen with Windows Live Mail 2009 on XP and 2011 on Vista. It is clear that users will no longer be able to sign in with a migrated account to synchronize contacts and calendar, and they won't be able to synchronize mail messages and folders using DeltaSync. Whether the programs will continue to work in other respects (e.g. as a POP3, IMAP and NNTP client) remains to be seen. Apart from this question of synchronizing mail, calendars and contacts with a Microsoft Email account, there is no change now or in the foreseeable future for Windows Live Mail 2012. Mail accounts configured to use POP3 or IMAP will continue to work as before, the default calendar and contacts lists will still be available and the other functions - RSS feeds and newsgroups - continue as before. Because of the many problems that update KB3093594 caused for some users, it has been re-released, now at version 5.0 dated 23 December 2015. The revised KB includes this text under More information : Known issues about this update<ul> <li>Issue 1: After you install this update (that was released before December 17, 2015), you may find that the program crashes soon after start. Solution: Microsoft has identified the cause and has released a fix that addresses the issue for affected users on applicable platforms. To fix this issue, install this update that's released on December 17, 2015. </li><li>Issue 2: After you install this update that's released on December 17, 2015, you may experience mail sync issues. </li></ul> Update 1 February 2016 <ul> <li>Issue 3: Some customers have reported other issues with the release on December 17, 2015. This update is no longer being offered while Microsoft investigates these issues farther. Server interactions will remain supported during this investigation.

Microsoft is researching this issue and will post more information in this article when the information becomes available.</li></ul> --- The re-issued patch d-Mail.msp updated Windows Live Mail 2012 and its program files to version 16.4.3564.1216. The direct link to the English language download is https://download.microsoft.com/download/6/D/7/6D7FD0CD-BF45-418A-B131-6483CA075D76/d-Mail.msp

This has been a known, serious problem for a month now. Others here are pointed to this thread for information yet there has been ZERO response of information for weeks now. Once again, in a long line of similar failures, the Microsoft Mail team has managed to screw their customers and do NOTHING to address the problem ....

Just fix it Microsoft. Stop releasing half-baked patches. Windows Live Mail should be able to work on Windows 10 with ActiveSync. Not everyone wants to use the "universal" Mail and Calendar apps.

Exchange Active Sync never got set after the d-mail .msp update ... I re-added the account. Yes - after applying the update, you have to remove the account then add it back again to refresh the server connection. You won't see a difference on the Server tab of the account's properties dialogue, but you will in any error message. Mine show Server: https://m.hotmail.com/Microsoft-Server-ActiveSync Any ideas why larger number of message fails to sync?? No, but there is some throttling in place, I suspect to ease the server load as hundreds of thousands - or possibly millions - of users suddenly start re-synchronizing all their folders and messages. Check the progress window (a single click on the Checking email status message opens it): if the download has stalled on Downloading message 0 of n , you won't get any further and might as well click Stop . The sync may continue after closing down the program, so right-click on the program icon in the notification area and select Show send/receive progress to monitor activity. Again, if it's stalled, Stop it. You may find that it has a go with another folder next time. Another problem is that sync seems to choke - and stall - on any attachment.

Microsoft still has a major problem on their mail servers. I have one email address that requires POP mail and another email address that requires IMAP-Mail. This is because they are on different MS mail servers. It took many hours to resolve this problem. I suspect I will have a problem in the future when MS upgrades all mail servers with the same software updates. This is a very poor way to do business for a swr provider..

I have one email address that requires POP mail and another email address that requires IMAP-Mail. This is because they are on different MS mail servers. Sorry, I don't understand. Microsoft Email accounts (ones with a mailbox at mail.live.com) are all provisioned for access via HTTP, IMAP and POP3. The choice is yours. The only change is that an account upgraded to Outlook Mail can no longer use the DeltaSync protocol to synchronize mail, contacts and calendar over HTTP that has been the default in Windows Live Mail since 2006. I use IMAP for one upgraded Microsoft Email account with no problems, and POP3 for some other Microsoft Email accounts just to make it possible to use complex message rules in Windows Live Mail. No two of my Microsoft Email accounts are hosted on the same server. This is a very poor way to do business for a swr provider.. What is a swr provider ?
