Version History

Data:26 Feb 2024
Nowość:You can now configure conditions (or exceptions) for your rules based on email headers. This lets you apply a specific action (e.g. add a signature) to emails that contain a defined header name, value, or both.
Date:17 Aug 2023
New:When configuring the Sent Items Update service in a hybrid environment, you can now manually configure the EWS connection to an Exchange server.
Fixed:In rare scenarios, images added by conditional placeholders would end up as attachments.
Fixed:Minor bug fixes.
Date:14 Sep 2022
New:Azure AD Graph API and Azure Active Directory Authentication Library (ADAL) have been replaced with more secure and resilient Microsoft Graph API and Microsoft Authentication Library (MSAL), respectively. These components are used when configuring the Sent Items Update service for a hybrid environment, which requires registering CodeTwo Exchange Rules in Azure Active Directory of a Microsoft 365 tenant.
New:The Microsoft 365 cloud step has been removed from the Sent Items Update configuration wizard for a hybrid environment. The Office 365 Germany cloud has been deprecated by Microsoft.
New:The new version of CodeTwo Exchange Rules Converter now lets you automatically transfer rules with the Auto respond action to CodeTwo Email Signatures 365. The transferred rules are available in the signature management app, under the Autoresponders group.
New:Microsoft .NET Framework 4.6.2 or higher is now required to install the Administration Panel. The program’s installer can automatically download and install the required version of .NET Framework.
Fixed:Minor bug fixes.
Date:31 Jan 2022
New:New simplified version of the HTML template editor, designed for intuitive use. The simplified editor experience is available:
  • on the Secure messages tab in the program's settings,
  • in Rules Tester, when composing a test email.
New:Upon opening the template library, the user is now asked to allow the program to download predefined templates from an external (CodeTwo) resource.
Fixed:Fixed various image-related problems that might have occurred with templates:
  • that contained conditional placeholders,
  • created on the Secure messages tab in the program's settings.
Date:27 Oct 2021
Fixed:The Sent Items Update service when configured for a hybrid environment failed to connect to Microsoft 365 (Office 365) using the automatic application registration option after Microsoft enforced the requirement for Azure AD applications to use the default scheme or verified domains in their ID URI.
Fixed:Improved synchronization of settings between multiple instances of the CodeTwo Exchange Rules Service.
Date:10 Aug 2021
Fixed:The Sent Items Update service could not obtain an EWS URL by using the Autodiscover service when configured in environments with the latest Exchange Server updates installed.
Date:09 Jun 2021
New:New HTML signature template editor, designed to make composing signatures much easier, faster and more intuitive.
New:New signature template library. It contains many predefined signature templates that can be quickly customized before loading them into the editor for further processing. 
New:Conditional placeholders added to the signature template editor. This feature lets you create custom placeholders that can contain multiple values. Which value replaces a conditional placeholder in a signature depends on a set of user-defined conditions that are checked as the signature is added to an email. Conditional placeholders can be used e.g. to add a generic phone number to an email signature if a sender has no phone number specified in AD, or to insert different marketing banners for selected users only.
New:CodeTwo Exchange Rules Converter, a stand-alone application that lets you automatically transfer your email signatures, signature adding rules and custom placeholders to the cloud signature product - CodeTwo Email Signatures 365.
Fixed:After reaching their recipients, encrypted or digitally signed emails to which the program applied a signature did not contain all the original email addresses specified in the To / CC fields.
Date:27 Oct 2020

Support for OAuth 2.0 authorization:

  • the Sent Items Update service uses OAuth 2.0 to connect to and communicate with Exchange Online;
  • to continue using the service in a hybrid environment, it is now necessary to register CodeTwo Exchange Rules in Azure Active Directory of the Microsoft 365 (Office 365) tenant configured in that environment. The program can perform the registration automatically (Microsoft 365 global admin account required), or you can choose to register the program yourself.
New:The program can now process messages that contain the CalendarPart property.
Fixed:The Sent Items Update service configured for a hybrid environment could not obtain an EWS URL by using the Autodiscover service.
Fixed:The Sent Items Update service could not find emails in the Sent Items folder if they were sent from Apple Mail installed on Mac computers.
Fixed:Messages for which an incident report was created by an Exchange Server would generate an error in the CodeTwo Exchange Rules Transport Agent log despite being correctly processed by the program.
Fixed:After importing rules and setting from another CodeTwo product, some entries generated in a log file would be incorrectly marked as errors.
Fixed:Improved handling of encrypted and digitally signed emails.
Date:29 Jan 2020
New:Improvements to the QR Code image insertion mechanism. QR Codes can now also contain more characters.
New:The names of CodeTwo Exchange Rules services have been revised to avoid ambiguity.
New:Optimized handling of HTML email signatures.
Fixed:Inserting side banners or a header section to HTML emails that were missing the <body> tags would delete the contents of those emails.
Fixed:After selecting to remove previous occurrences of an email signature from a conversation thread, the program would also remove email reply separators if that signature ended with empty HTML paragraphs.
Fixed:On rare occasions, the Sent Items Update (SIU) service would fail to connect to certain Exchange environments via Exchange Web Services.
Fixed:Minor bug fixes.
