I Exclaim that Exclaimer works

We are currently in a Hybrid environment where our Exchange server is still on-premise. Unfortunately, Microsoft only supports this feature for customers who are in a full Office 365 environment. We did previously utilize a tool from CodeTwo, however it has the same limitations as Microsoft's offering.

Exlaimer has allowed us to mass deploy email signatures to all our staff and manages to do so in our hybrid environment. Not only that, but it allows email signatures to be sent on all emails including from mobile devices. This is helpful as not all users use the same phones, some users have Androids, while others have iPhones. We also don't have a standard email client on mobile devices, so it saves us a lot of time from configurating each individual mobile device.

Lastly, this helps all the users who still prefer to use Outlook Web App instead of Outlook on Desktop. In summation this allows us to set up a strict standard for signatures without the need to configure anything on any devices outside of the initial sync client.

We have configured different templates for different departments. That has been very helpful as we can tailor the signature to better match that department's personality.

We do utilize the feature that disables the signature when it detects one, as well as the feature to disable the signature during auto-replies.

We have not utilized their scheduling feature as we do not feel like that is needed in our organization.

From what we can see on our end, Exclaimer does seem to be secure. During the initial set up I did not experience any sort of red flags for security. One part of the setup requires you to allow access to your Azure environment, and it is made very clear that once it has been completed you should manually remove the access. I do appreciate that they go over that, but I can also see some users ignoring or skipping that step.

Outside of that, I can't say I have a hard stance on their data security.
