Active Directory attributes in CodeTwo Email Signatures for Office 365

In this article you can find information about the Active Directory attributes available in the Editor when you use CodeTwo Email Signatures for Office 365.

CodeTwo Email Signatures for Office 365 is aimed at Office 365 environments. The program supports all the single-value attributes available in Office 365 (Azure Active Directory) and Azure AD Graph API. Multivalue attributes are currently not supported (see this article to learn how to check if an attribute is single- or multivalued).

If you want to use custom AD attributes (such as CustomAttribute1-15, Initials, HomePhone, etc.) in the Editor (as shown in Fig. 1.), these attributes need to be synchronized to the CodeTwo software. Learn how to use custom attributes in CodeTwo Email Signatures for Office 365

Placeholders may not work right after you configure your signature rules for the first time or after resetting Azure AD cache. This is because placeholders' values are populated by cached data, not by data taken directly from your Office 365.

A cache mechanism has been added to speed up message processing and prevent software from querying your Azure AD too often. The software automatically refreshes its cache every 60 minutes. You can manually reset the Azure AD cache on the Manage tenant pages in CodeTwo Admin Panel. Learn more


Use the Photo placeholder (see Fig. 1.) to add users' AD photos to signatures. You can easily upload photos to Azure Active Directory by using our freeware application, CodeTwo User Photos for Office 365. The program uploads users’ photos to Exchange Online mailboxes and associated services. It lets you manage photographs collectively, without having to run the Set-UserPhoto cmdlet separately for each user.
