Version History

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 for Office 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.
Date:24 Jan 2019
