Follow this guide for step-by-step instructions on how to automatically install and update the legacy CodeTwo Signatures Add-in for Outlook (COM Add-in) for users in your organization using GPO or Microsoft Intune. You can deploy the add-in for all users, selected security groups, OUs, or AAD groups. Use the links below for instructions.

• Deploy the add-in to the whole organization
• Deploy the add-in to a security group
• Deploy the add-in to an Organizational Unit (OU)
• Update the add-in
• Deploy the add-in using Microsoft Intune

If you prefer individual users to install the add-in manually on their machines, see this guide.

If you prefer to use an add-in that can be deployed organization-wide from the Microsoft 365 admin center, try the modern CodeTwo Signatures Web Add-in for Outlook and OWA, co-engineered with Microsoft. See deployment instructions

11. The next time a user in your organization restarts their machine and logs in, CodeTwo Signatures Add-in for Outlook should be installed automatically at startup (Fig. 11.). The user doesn’t need to have local admin rights to install the software correctly.

12. (Optional) If the add-in is not installed, after the restart, it might be that the GPO settings have not propagated yet. You can use the gpupdate /force command in the Run (Windows +R) console on the client’s machine to force-apply the GPO settings. After the user logs out and logs in, the add-in should be installed immediately.
13. After installation, the add-in is available in Outlook and opens in the right pane. (Fig. 12.). Users can change its width to resize it. Using a dedicated button on the ribbon hides/shows the add-in pane.

Fig. 12. This is how CodeTwo signatures add-in appears in Outlook right after installation.

14. To have CodeTwo signatures automatically added to Outlook, each user needs to click Sign in in the add-in pane. When a Microsoft sign-in screen appears, a user needs to sign in using their Microsoft 365 work account credentials and accept the permissions to synchronize the add-in with Outlook and get signatures.
15. When a user is signed in, the add-in pane shows signatures that are available for them. Depending on your organization's settings, these signatures can be added automatically (when users compose a new message or reply to/forward a message) or users can add them on their own in compose mode in Outlook, just as they would normally add Outlook signatures: they need to go to the Message tab, click Signature on the ribbon and choose any signature that is available.

Deploy the add-in to a security group

This section explains how to apply the GPO which installs CodeTwo Signatures Add-in for Outlook for all members of a security group.

1. Follow steps 1-4 from section Deploy the add-in to the whole organization.
2. Select the newly created GPO. In the Security Filtering section, click Add (Fig. 13.) and select the security group or (groups) to which you want to deploy the add-in.

3. On the Delegation tab, make sure the security group(s) you have chosen in the previous step and the Authenticated Users group are all listed (Fig. 14.). Use the Add button if any group is missing. Next, click Advanced to manage group permissions.

4. For the GPO to work correctly, you need to assign Read permissions to the Authenticated Users group (Fig. 15., left), and assign the Read and Apply group policy permissions (Fig. 15., right) to the security group(s) you selected for the add-in deployment.
