Set Outlook Web App signature with image using PowerShell

Applies to Exchange 2016, Exchange 2013, Exchange 2010 and Exchange Online (Office 365).

In corporate environments central management of email signatures is a must – you don’t want users messing up the company’s image by sending out emails stamped with notes in Comic Sans, lacking crucial contact info, etc.

So it’s a good thing that Microsoft Exchange platforms offer several means of controlling the email footer situation in your network. The most popular one is the Apply disclaimers feature available via Exchange transport rules, which I’ve talked about extensively on this blog (see respective guides for Exchange Online, 2016, 2013, 2010 and 2007).

How to set Outlook Web App signature with image using PowerShell

Another way of deploying email signatures from one place across an Exchange organization, is using the Set-MailboxMessageConfiguration PowerShell cmdlet with the -SignatureHTML parameter.

This method allows you to populate the Email signature box in end-users’ Outlook Web App / Outlook on the Web clients with any type of HTML content: text, tables, images, links, etc.

How to create company-wide email signatures and disclaimers in Office 365

Below you will find details on what you have to do to set up your own server-level automatic email signature or disclaimer using the built-in Office 365 tool.

A little info about the tool: like most today’s email signature solutions, it supports HTML content such as tables, images and font formatting, but In contrast to e.g. Google Apps for Business, it also allows for automatic personalization of individual signatures.  Limitations include no option to insert the signature directly below the latest email reply or forward and lack of preview on the end-user’s side (learn more…).

Steps to set up an email signature policy in Office 365:

  1. Log in to the Office 365 portal using an Exchange Online administrator account and access the Microsoft 365 admin center as shown in the below image:

How to set up email signatures on Exchange Server 2016

Possibly the biggest surprise brought about by the release of Exchange 2016 is… how similar it is to Exchange 2013. In fact, in terms of email signature management it’s pretty much identical (if you’re familiar with the 2013 version of Microsoft’s email server, you’ll see what I mean). However, many of you may have never had the opportunity to poke around Exchange 2013, so let’s get to work:

NOTE: This solution comes with several limitations, which I discuss in the last section of the article.

How to set up automatic email disclaimers on Exchange 2007

Exchange 2007 was the first edition of Microsoft’s messaging platform to introduce Hub Transport rules and with them a built-in append disclaimer action. The options available in this action are very basic, the most important limitation being lack of support for dynamic Active Directory fields (see this article for more). Due to this, the action can only be used for creating automatic disclaimers (legal, financial, etc.) and general company signatures without users’ details.

Once you have the Hub Transport role installed on your Exchange 2007 server you can start working on automatic disclaimers for your organization.

Steps to set up automatic email signatures and disclaimers on Exchange 2007:

  1. Open the Exchange Management Console, expand Organization Configuration, select Hub Transport, click the Transport Rules tab in the middle Result Pane and in the Actions Pane on the right click New Transport Rule… (Fig. 1). This will trigger the New Transport Rule creation wizard.
