harmon.ie for Outlook - Administrator's Settings

This article explains how administrators can centrally and remotely control all the settings of harmon.ie for Outlook.

What can be centrally managed?

SharePoint sites: Add and configure SharePoint sites. Sites can also be provisioned using the user profile service.
Documents options: Control the Locations view, navigation, and document management.
Favorites: Set favorite locations.
Upload options: Options for uploading documents to SharePoint.
Email options: Options for uploading emails to SharePoint.
Search options: Options for searching on SharePoint.
Teams options: Controls working with Teams.

Troubleshooting: Options used by support when troubleshooting harmon.ie.

An administrator can:

Set default startup values that the user can later change.
Force values for the user, which disables them in the harmon.ie Options dialog, preventing the user from changing them.

How to change the harmon.ie settings?

Changing harmon.ie settings is done by adding keys to the harmon.ie registry tree, using one of the following methods:

By adding registry keys to the harmon.ie installation file (.msi). Read customize the harmon.ie installation file to learn how.
By centrally updating registry keys. Windows provides several methods for updating registry keys. Read Distributing Registry Changes to learn how.

Setting default values

harmon.ie root key:

The root key under which the administrator should add the harmon.ie keys is:

For provisioning the product for the current user only: HKEY_CURRENT_USER\Software\Mainsoft\Prefs\.
For provisioning the product for all users on the machine, the exact location is different for each operating system, as shown in the table below:

OPERATING SYSTEM	KEY
32-bit Windows running 32-bit Office	HKEY_LOCAL_MACHINE\Software\Mainsoft\Prefs\
64-bit Windows running 32-bit Office	HKEY_LOCAL_MACHINE\Software\Wow6432Node\Mainsoft\Prefs\
64-bit Windows running 64-bit Office	HKEY_LOCAL_MACHINE\Software\Mainsoft\Prefs\

harmon.ie registry keys

The tables below list the optional registry keys that can be added to set default values for the users.

Please read the list of common keys first.

harmon.ie common keys:

Here is a list of common harmon.ie keys to set:

Sites: Set initial SharePoint sites for users. This simplifies starting to work with harmon.ie, as users can immediately see their documents.

There are other ways to configure sites for users:
- You can provision different sites to different groups of users, using the Published Links mechanism in SharePoint’s profile service. Read all about it here.
- You can add Sites I’m following to users’ sites list, by setting the ShowFollowedSites key (see below).
After provisioning a new site for users, they can click the Refresh button () in the All Locations view to update their site list (in harmon.ie 6.5 or later).
DefaultSocialServer: Set the SharePoint site that is used as the social server – this is the SharePoint server running the User Profile service application. By defining this site, users have access to many social features.
HideSocialFromNavigation: Set to True if the social server does not include documents and should be hidden from the sites list.
ExcludeLibraryByNameFilter: Hide SharePoint libraries and technical lists non-relevant to the users. For example: Site Assets, Form Templates, and Style Library.
If necessary, restrict SharePoint sites from users. Read Restricting SharePoint sites to users for more information.
If your organization requires it, you may replace the harmon.ie logo, icons, links and labels with your company's logo and labels. They will appear in the harmon.ie sidebar and ribbon-buttons. Read Modify harmon.ie labels and images for more information.
ShowFollowedSites: Set to True, and then when you follow SharePoint sites from the SharePoint Web page, harmon.ie automatically shows these Sites I'm following in the Sites list.
SyncFavoritesWithMyLinks: Set to Document Libraries to add the links defined in the Document Libraries group of My Links to the favorites list in harmon.ie.
MoveEmailOnDrag: Set to True to delete email messages uploaded to SharePoint, or to False to leave them in the Inbox as well as on SharePoint.
UniqueEmailName: Set to True to save email messages to SharePoint with a unique name.

Add a String Value called user-field-name and set to the user field name (default: UserName). Add a String Value called password-field-name and set to the password field name (default: Password).	When connecting to SharePoint sites with browser authentication: Set this key if you wish harmon.ie to save the user name and password, and suggest them for future browser authentication logins. You can override the values of user-field-name and password-field-name for a specific site using the BrowserAuthentication\fill-office-forms-authentication\<site URL> key.		6.1

Thus we make sure that IE control brings and uses fresh cookies in each authentication process.		6.7

Forcing values for users

To force a value for the users, and disable it in the harmon.ie Options dialog, add a new value to any of the harmon.ie keys listed above:

KEY NAME	VALUE NAME	VALUE TYPE	VALUE DATA
< any >	Force	DWORD	1

Note: To force a favorite location, define the Force value in the key FavoriteList\<name>. Defining the Force value in its subkeys has no effect.

To provision URLs:

We support this URL format for setting a SharePoint site:

https://<server>/<site>

If a document library or folder name is specified, it is trimmed from the URL.

We support these URL formats for provisioning favorite locations:

https://<server>/<site>
https://<server>/<site>/<document library>/
https://<server>/<site>/<document library>/<folder>

Notes: Do not specify aspx pages or query parameters.

Tip: To find out the SharePoint location using harmon.ie, right-click it and select Copy > Address, then remove aspx pages and query parameters.

Site provisioning example:

Registry definition for a site called MySite:

The site is added to harmon.ie:

Combining administrator and user preferences

To build the list of sites available in the harmon.ie sidebar each time Outlook starts, the SharePoint sites defined in the registry are combined with the sites that the user configured via the harmon.ie Options.

This is true for building the favorite locations list as well.

Administrator preferences, set in HKEY_LOCAL_MACHINE, do not take precedence over user preferences, unless the administrator defines forced values. Specifically, if the user changed his preferences, and the administrator provisioned the product afterwards, the user preferences are not replaced.

Administrator preferences set in HKEY_CURRENT_USER, do replace the preferences set by the user. Unless the administrator defined forced values, the user can overwrite the preferences using the harmon.ie Options dialog.
