Windows Unplugged

Summary:   Microsoft is deprecating(discontinuing) the DeltaSync protocol supported by Windows Live Mail

 

Comments:

• DeltaSync is an email protocol used in Windows Live Mail(2012, 2011¹, 2009¹) for Sending and Receiving mail
• DeltaSync supported Outlook.com type email accounts(Outlook.com, Live.com, Hotmail.com, and MSn.com)
• DeltaSync provided synchronization of email messages and folders/sub-folders between the Outlook.com type accounts configured in Windows Live Mail and the corresponding account’s web based Inbox.
• Sending, Receiving, and Synchronization will cease to function once an Outlook.com type account is migrated to the new backend server on the Office 365 Platform

 

Recommendations:

• For those using the DeltaSync protocol in Windows Live Mail 2012 switch to one of the other two protocols(IMAP or POP3) – See ‘How-To’ sections below 
  • IMAP supports synchronization of messages, folders, and subfolders between the local client(Windows Live Mail 2012) and the Outlook.com type account(Outlook/Hotmail/Live/MSn.com) web based INBOX
  • POP3, does not support synchronization of messages, folders, subfolders between the local email client and the account’s web based INBOX.  (NOTE: To use POP3 in a local client, the POP3 setting must be enabled in the account’s web based user interface(UI) Settings).

 

How-To:

• POP3 and IMAP settings for Outlook.com type accounts(Outlook.com/Hotmail.com/Live.com/MSN.com)

• IMAP server name imap-mail.outlook.com

• IMAP port 993

• IMAP encryption method SSL

• POP server name pop-mail.outlook.com

• POP port 995

• POP encryption method SSL

• SMTP server name smtp-mail.outlook.com

• SMTP port 587
