How to set default and reply signatures for Client-Side with Microsoft 365 subscriptions

Scenario

You are using Exclaimer with Microsoft 365 and Client-Side deployment and wish to set certain signatures to apply by default, such as when composing a new email thread or when sending a reply or forward email.

Resolution

You can use signature rules in the Manage screen or the Exclaimer Outlook Add-In pane to set a specific signature to apply as default in two ways: the default for new emails, and the default for replies and forwarded emails. Your defaults then apply using the Exclaimer Outlook Add-In.

To set a Client-Side signature as a default:

Select an option below to view the related instructions:

Option 1: Set a signature as a default in the Exclaimer portal

From the menu sidebar, select Signatures, then locate the signature you wish to set as a default and select Manage Rules.
Select the Enable tab. The default options are found in the Client-Side section under Apply as default for.

_{The Apply as default for checkboxes set this signature as a default.}
Select a checkbox to choose a default type for this signature:

Select New messages to apply this signature as a default for new emails.

Select Replies and forwards to apply this signature as a default for email replies and forwarded emails.

Tip! You can set a signature as a default for both types of application. This signature will be applied to all emails as a default.

NOTE: If you set more than one signature as a default, the one which is higher in the All Signatures list will take priority. Re-order your signatures to change the priority.
To remove a default setting, deselect the checkbox.
In the unsaved changes banner, select Save.
Run a manual data synchronization to sync your signatures with Outlook.
Install the Exclaimer Outlook Add-In. Your default signatures are now applied when you send an email using Client-Side deployment.
To view your default signatures, open your email client and view the Add-In signatures pane. Icons are displayed above signatures - if a signature has been set as a default, the corresponding icon is highlighted.
