Custom attributes

CodeTwo Email Signatures for Office 365 lets you use your own Active Directory attributes when composing signatures. These custom attributes (also known as Directory extension attributes) include, for example: CustomAttribute1-15, Initials, HomePhone, Notes, Pager, PostOfficeBox, WebPage, etc.

If you want to use custom attributes in the signature editor, you have to make sure they are in sync with the program. Proper synchronization will depend on your environment.

Hybrid environments

If you have a hybrid environment, it is essential to configure Microsoft Azure Active Directory Connect properly. By default, custom attributes defined in your on-premises Active Directory are not synced to your Azure Active Directory. Therefore, they are not available to CodeTwo Email Signatures for Office 365 and you are not able to add custom placeholders in the signature editor.

Our program lets you verify if custom attributes are synchronized. To do that, open the User Panel, enter the management section of a chosen tenant by clicking the Manage tenant (ESIG for O365 edit button 14px) button next to the tenant's name, then select User AD attributes from the left menu. If your custom attributes are not synced, the section will look like below (Fig. 1.).

Info

If you do not see the Custom attributes subsection in User AD attributes (Fig. 1.), contact CodeTwo Support.

To fix the synchronization problem, open your Azure AD Connect. First, enable the Directory extension attribute sync feature in the Sync, Optional Features section, as shown in Fig. 2.

Second, navigate to the Directory Extensions section (Fig. 3.) by clicking Next, select your custom attributes (e.g. extensionAttribute[1-15], initials or homePhone) from the Available Attributes list on the left and move them to the Selected Attributes list on the right. Finally, complete the wizard by clicking Next.

When you finish the configuration, your custom attributes will be synchronized with Azure AD and the corresponding custom placeholders will be available in the signature editor. Click here to learn how to add them to your signatures.

Non-hybrid environments

By default, in non-hybrid (cloud) environments custom attributes are not synced to CodeTwo Email Signatures for Office 365. Using PowerShell commands is necessary to access them. That is why our program features a ClickOnce application called CodeTwo Email Signatures for Office 365 Custom Attributes Sync. The app is installed locally on your computer and lets you quickly synchronize custom attributes using a 3-step wizard (Fig. 4.).

To install the application, open the User Panel and enter the management section for your tenant by clicking the Manage tenant (ESIG for O365 edit button 14px) button. Select User AD attributes from the left menu and click the Synchronize attributes button located at the bottom (Fig. 5.).

Info

If you do not see the Custom attributes subsection in User AD attributes (Fig. 5.), contact CodeTwo Support.

After the app is installed, you can launch it directly from the Start menu. A simple wizard guides you through the configuration. Once you enter your global admin credentials (Fig. 6.) the program will synchronize your custom attributes to the Azure AD Cache (to learn more about the program's components, click here).

Important

CodeTwo does not store, copy or have access to your global admin credentials. These personal data are used to access your Azure AD via PowerShell, using standard Microsoft procedures. If you select the option to store your credentials in the program, they will be encrypted and kept only locally.

You need to run the Custom Attributes Sync application each time you modify your custom attributes and want to make them available to CodeTwo Email Signatures for Office 365. Such a solution protects your data - you enter your global admin credentials only when they are required for the synchronization.
