We are using Microsoft 365 Exchange Online. Can I create a company-wide signature template which is something Exclaimer?
You can create a disclaimer in Exchange Online as it was in Exchange on-premises which can include some variables indicate properties from the particular users. You can make a rule in Exchange Online to tack on a signature and even make custom ones based on users. The format can be HTML with external links to images as well. But, the quality of the result is far to have the same quality than Exclaimer, or equivalent products.
Although you can do this in Microsoft 365 natively but there are a few issues. For example, people cannot see it, so if they add their name or anything to the bottom of an email, you get a duplicate. We looked at Code42’s software, which provides more options, but in the end the company decided not to enforce a template for everyone.
Follow below steps to set up company-wide email signature natively in Microsoft 365 Exchange Online.
