Outlook Addin

Outlook for Web (OWA) and New Outlook
We really tried to develop an add-in for new outlook and OWA. Unfortunately, the official office-js API from Microsoft does not allow us to create a working regimail add-in. The main reason is the lack of API functionality provided. This is what we are missing (12/2024):
- Composing regimails
- Reading regimails
- No API to set/replace body or delete/replace attachments (source). The alternative would be to create a new message with decrypted content in parallel. But see next point.
- No API to create a new message in inbox folder with custom content.
- Only an API to open the compose form, but this does not allow us to save to the correct location except of drafts folder. It would become sent or a draft. Both we don't want.
In addition, the API version provided by the users environment must support the needed API functionality. For on-prem installations of Exchange 2016 and 2019, the maximum API requirement set available is 1.5. But for the most functions required, an API requirement set of 1.11 or even higher is needed. Such API requirement set levels are only available if your Outlook is connected to Exchange Online from Office 365 (hosted by Microsoft) (source). Microsoft also did not yet announce, what API requirements set it will support for upcomming Exchange 2025.
Therefore, we recommend you to not update to Outlook new if you want to keep your current regimail add-in working!
Here is how you can stop Outlook from automatic update to Outlook new.
What comes next?
Until now, we focused on the official new office-js API provided by Microsoft. But there is the option to communicate with the connected Exchange server directly, offering some more functionality than the office-js API. We are investigating the possibility to gain what we want from this path. But it needs time, so please be patient.
We will keep you updated on this page.
Outlook Legacy
Supported versions
The current AddIn for Microsoft Outlook is available for the following versions:
- Outlook 2019 (32 Bit & 64 Bit)
- Outlook 2021 / Office 365 (32 Bit & 64 Bit)
- Outlook 2024 / Office 365 (32 Bit & 64 Bit)
Please respect that we're no longer supporting Outlook before 2019. Running this e-mail client is also no longer secure. Please consider upgrading to a newer version or how about trying Mozilla Thunderbird?
Functions
The AddIn for Microsoft Outlook offers the following functions:
- create new regify e-mails
- forward, reply and reply all using regify
- reconvert regify mails to ordinary e-mails
- automatically reconvert while receiving
- configure regify settings (account settings)
- invite new users to regify
Setup
The Outlook AddIn is installed automatically (in the correct version) during setup of the regify client. If you do not like to install the Outlook AddIn during setup, please refer the "regify client software deployment documentation" for possible options. It is provided to you by your regify provider.
