== Outlook add-ins ==
Outlook [[Plug-in (computing)|add-ins]] are small additional programs for the Microsoft Outlook application, mainly purposed to add new functional capabilities into Outlook and automate various routine operations. The term also refers to programs where the main function is to work on Outlook files, such as [[Synchronization (computer science)|synchronization]] or [[Backup|backup utilities]]. Outlook add-ins may be developed in [[Microsoft Visual Studio]]<ref>{{cite web|url= https://www.pcworld.com/article/159204/top_10_reasons_to_use_outlook.html|title= Top 10 Reasons to Use Outlook|date= February 10, 2009|work= PCWorld|access-date= September 17, 2017|archive-date= September 17, 2020|archive-url= https://web.archive.org/web/20200917054053/https://www.pcworld.com/article/159204/ms_outlook_enterprise.html|url-status= dead}}</ref> or third-party tools such as Add-in Express. Outlook add-ins are not supported in [[Outlook Web App]].

From Outlook 97 on, Exchange Client Extensions are supported in Outlook. Outlook 2000 and later support specific [[Component Object Model|COM]] components called Outlook Add-Ins. The exact supported features (such as [[.NET Framework|.NET]] components) for later generations were extended with each release.

[[File:Outlook connector.png|thumb|Hotmail Connector setup screen]]
''Microsoft Outlook Hotmail Connector'' (formerly ''Microsoft Office Outlook Connector''), is a discontinued and defunct free add-in for Microsoft Outlook 2003, 2007 and 2010, intended to integrate [[Outlook.com]] (formerly Hotmail) into Microsoft Outlook. It uses DeltaSync, a proprietary Microsoft communications protocol that was formerly used by Hotmail.<ref>{{cite web|url=http://office.microsoft.com/en-us/outlook-help/microsoft-office-outlook-hotmail-connector-overview-HA010222518.aspx|title=Microsoft Office Outlook Hotmail Connector overview|publisher=[[Microsoft]]|archive-url=https://archive.today/20130128151603/http://office.microsoft.com/en-us/outlook-help/microsoft-office-outlook-hotmail-connector-overview-HA010222518.aspx|archive-date=January 28, 2013|work=[[Microsoft Office website]]}}</ref>

In version 12, access to tasks and notes and online synchronization with [[MSN Calendar]] is only available to MSN subscribers of paid premium accounts. Version 12.1, released in December 2008 as an optional upgrade, uses [[Windows Live Calendar]] instead of the former [[MSN Calendar]]. This meant that calendar features became free for all users, except for task synchronization which became unavailable. In April 2008, version 12.1 became a required upgrade to continue using the service as part of a migration from [[MSN Calendar]] to [[Windows Live Calendar]].<ref>{{cite web |url=http://ask.officelive.com/smallbusiness/blogs/team/archive/2009/04/02/outlook-connector-users-you-must-upgrade-to-a-new-version.aspx |title=Transition information for former Office Live Small Business customers – Manage Office 365 – Office 365 – Microsoft Office 365 Community |publisher=Ask.officelive.com |access-date=June 15, 2013 |archive-date=March 23, 2020 |archive-url=https://web.archive.org/web/20200323175849/https://products.office.com/en-us/home?ms.url=office365com&rtc=1 |url-status=dead }}</ref>

=== CardDAV and CalDAV Connector ===
Since Microsoft Outlook does not support [[CalDAV]] and [[CardDAV]] protocol along the way, various third-party software vendors developed Outlook add-ins to enable users synchronizing with [[CalDAV]] and [[CardDAV]] servers. [[Nextcloud]] recommends the Open Source Caldavsynchronizer<ref>{{Cite web |last=Poortvliet |first=Jos |date=2016-11-14 |title=Nextcloud offers CalDav Synchronizer for Outlook users |url=https://nextcloud.com/blog/nextcloud-offers-caldav-synchronizer-for-outlook-users/ |access-date=2025-05-19 |website=Nextcloud |language=en}}</ref>.
