How to Setup a Company-Wide Email Signature in Office 365 Exchange Online.
Office 365 Business with Exchange Online, gives you the ability (such as Exchange 2016 & 2019), to set up a corporate email signature, which applies to any email sent by any user or device of the company. A company-wide email signature is configured on the server side, and therefore ensures that all of your company's outgoing e-mail messages will have the same signature format and details for your organization, and eliminates the ability to add other details to the signature that you didn't want.
Although adding a organization-wide email signature has many benefits, on the other hand it has some limitations, as mentioned below.*
* Note: To bypass these limitations, you can use a third-party app from CodeTwo or Exclaimer.
Limitations of a company-wide signature on Office 365 or Exchange:
- The signature is not visible to the users when composing an email.
- The signature is always added, at the bottom of the email conversation.
- You cannot embed an image directly in the signature. If you want to use an image, you'll need to use a public URL for that image.
- The users don’t have the ability to choose a different signature, if they want to.
- An HTML-formatted e-mail signature is not displayed correctly when sent by devices that do not use Outlook as an e-mail client.
In this article you 'll find step by step instructions, on how to create and customize an email signature for your company on the server-side by using Exchange transport rules (Exchange 2019 & 2016).

This is a good article. We have two domains in our office365 account where we have pretty much two companies running in one. Half of the people send emails as user@domain1.com and half of the other users send emails as user@domain2.com. How can i create different signatures for those two domains?
