Exclaimer cloud signatures for office 365

As we all know exclaimer have been in the auto self signed signature market for a long period of time.

I have been working on the on premise version of this product for a quite period of time.

When we talk about the on premise solution based on my experience i would say its definitely a WOW factor. It is loaded with bundles of options by which you can customize the signature per department basis. Even you can give  granularity till each and every user .

If you are an HTML expert then you can play around with the signatures on your own  and make more customization. It gives you the flexibility to modify each and every signature from the source code which is amazing.

I thought to explore the cloud signature for office 365 .In this article we will have a detailed review of the installation and configuration of exclaimer for office 365 environment.


Office 365 subscription with Microsoft.

Admin account in the office 365

Ex-claimer  for office 365 subscription

After you are subscribed for office 365 for exclaimer you will get the below information


Specify the domain name


Then login with your office 365 admin account



Then you will be prompted to read the directory data


Once granted it establishes a connection with the Azure directory


On a successful sync you will get the below information


After establishing synchronization ,now we need to set up a connector inorder to route the emails to exclaimer cloud so that they can apply email signatures to outgoing email.

In-order to achieve this we need to establish connectivity between office 365 and exclaimer cloud.

Inorder to set this up first login with your username and password


Now we have an option to set up signatures for all users in your organization or only for specific users.

If you want to set signatures only for few users then create a group and add all those users in office 365. Since the azure directory is already synced when you type the group name it would be able to pick it up.


Now we need to perform the below actions:

Create Send connector – from your office 365 to Exclaimer cloud

For doing that login with admin privilege on your office 365 portal – Go to mail flow – click connector and create new connector


Make sure to  select only the first option else  your outbound emails will be affected.


Proceed to the next step and smart host it to the below  exclaimer smtp server



In the similar way we need to create  a receive connector


Now we need to enter ,By verifying that the subject name on the certificate that the sending server uses to authenticate with
Office 365 matches this domain name (recommended)’. In the field below, enter smtp.exclaimer.net then click ‘Next’:


Now we need to create a rule exactly as below with same values


As we can see the idea behind creating this rule is to forward only genuine emails to the exclaimer cloud and this is very mandatory. The rule is pretty simple and going through the rule will give a clear idea behind them.

On a successful configuration of the above things you can login successfully to your exclaimer for cloud


This is the place where we can create a new signature, Import a signature template designed by your development team or use the existing template which is very good.


Below are the available fields in the signature template provided . It has good default templates which is very good. It pulls all the information from the value eg: Telephone, organization, address on every users mailbox. So we need to make sure that the newly created mailboxes is populated with the values that are required in the template you have chosen.


Below is the sample of signature applied from the exclaimer cloud.



I’m always positive and will definitely recommend Exclaimer for any one based on my personal experience with the on premise version. If Microsoft releases any new version of Exchange i’m sure there will be a supported version of this product without any delay.

The Exclaimer cloud version is too  awesome and also it simplifies more by having the setup in the cloud and you just need to create the signature which is amazing. And the exclaimer support is always instantaneous without any delay based on my real time experience.

    Really great review, very in-depth. We did a comparison between CodeTwo and Exclaimer here. https://www.osh.co.za/codetwo-vs-exclaimer-email-signatures-office-365-speed-function-spf-dkim-designing-html-csat/ Both are really great products.
