CodeTwo Signatures Add-in for Outlook - global installation

Follow this guide for step-by-step instructions on how to automatically install CodeTwo Signatures Add-in for Outlook for users in your organization using GPO. You can deploy the add-in for all users, selected security groups or OUs. Use the links below for instructions (if you prefer individual users to install the add-in manually on their machines, see this guide).

Read this before you install

For the add-in to work, the CodeTwo software needs to work in client-side or combo mode (learn more about signature modes). You also need to prepare an email signature template and assign users who should get it. To do so, create and set up a client-side signature rule(s) in the Manage Signatures App by following our Quick guide.

The add-in requires .Net Framework 4.7.2 installed on users' machines to work correctly.

  1. (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.
  2. 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.

  1. 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 Office 365 work account credentials and accept the permissions to synchronize the add-in with Outlook and get signatures.
  2. 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. Learn how to use the add-in.
