CodeTwo Signatures Add-in for Outlook
CodeTwo Signatures Web Add-in for Outlook, co-engineered with Microsoft, adds signatures to emails in Outlook for Windows, Outlook for Mac (early access) and Outlook on the web (OWA). See the video below or continue reading the article to learn how the Web Add-in works and how to use to manually select different email signatures.
Information for admins
The Web Add-in is a component of CodeTwo Email Signatures for Office 365. If you want your Microsoft 365 users to get automatic signatures in Outlook, you need to:
If you are looking for instructions on how to deploy and use the classic CodeTwo Signatures Add-in for Outlook (COM Add-in), refer to this section. For a comparison of the two Outlook add-ins, see this article.

Once you start typing an email in Outlook, a signature is automatically inserted into the email body, according to the configured client-side rules (Fig. 1.). For example, a different signature is inserted to new messages and a different one to replies/forwards. The Web Add-in uses the newest event-based activation feature from Microsoft to completely automate the signature adding process (there's no need to launch the add-in first).
If the event-based activation doesn't work in a desktop Outlook app, it may be that your version of Outlook doesn't fully support the Web Add-in. Try updating your Outlook or change the Microsoft Apps update channel, as described in this article by Microsoft. You can still add signatures manually, as described below.
To insert a signature manually, first click the CodeTwo Signatures button on the ribbon (Fig. 2., item 1). Next, in the pane that opens, click Use this signature below the signature that you want to use (Fig. 2., item 2).
To open the Web Add-in's pane while composing a message in Outlook on the web (OWA), click CodeTwo Signatures at the bottom of the message. If you can't see the button, click More apps () first, as shown in Fig. 3.
If you want the Web Add-in's pane to automatically open each time you compose an email, pin the pane to Outlook by using the button shown in Fig. 4. Click the pin button again to unpin (hide) the pane.
If you have multiple accounts added to your Outlook desktop app and you change the account in the From field while composing an email, the Web Add-in's pane will show email signatures set for the selected account. After the account change, you need to manually add a signature to an email by clicking Use this signature in the pane, as shown in Fig. 2.
If you are sending an email as or on behalf of another account, the Web Add-in will:
- continue to show your own email signatures (default behavior), or
- show email signatures configured for the user selected in the From field (this behavior needs to be set by the admin).
Either way, after selecting a new email address in the From field, you still need to manually add a new signature to an email.
Using the Outlook / Cloud toggle
This feature needs to be enabled by the admin. Learn more
If you see the Outlook / Cloud toggle in the Web Add-in's pane (Fig. 5.), you can use it to switch between client-side (Outlook) and server-side (cloud) signatures.
- In client-side (Outlook) mode, the Web Add-in works as described above in this article.
- In server-side (cloud) mode, signatures are added in the cloud, after you send an email. However, you can use the Web Add-in to preview server-side signatures, as described in this article.
CodeTwo Signatures Add-in for Outlook adds client-side signatures to emails in Outlook for Windows.
To have access to client-side signatures, you need to sign in to the add-in with your Microsoft 365 account credentials. CodeTwo signatures added by the COM Add-in are available just like any other Outlook signatures. If they are set as default by your organization's admin, they are added automatically when you compose a new message or when you forward/reply to an email (Fig. 6.).
You can also add them from your Outlook ribbon - in compose mode, go to the Message tab, click Signature on the ribbon (Fig. 7.) and choose any signature that is available to you (if a signature is already added to your message, it will be replaced with the one you selected).
Click the add-in button on the Outlook ribbon to show/hide the add-in pane. Note that the button might not be visible if you open a message in a new window. You can use the add-in pane to:
- quickly preview the signatures that are available to you,
- force signature refresh (Fig. 8.) if you do not want to wait for automatic signature synchronization that occurs every couple of minutes,
- sign in or sign out of your user account.
