When I log into one of our servers my email signature works but on another not.
Outlook when loaded on a server adds a First-Run registry line that needs to be the same on other servers or your users could be missing signature lines in email. Here is the fix for that issue on networks with more than one outlook hosting server.
Why in the world does my Signature File disappear when I login?
This issue is related to how Microsoft handles the installation process of Outlook.
When Outlook is installed on more than one server the registry key for the setup value First-Run needs to match any and all other servers hosting Outlook.
In the case of a cloned server we need to Export the Registry key from the first server and merge that key with the second server.
When both servers have the same First-Run keys then your signature files should be good to go.
Export from SERVER-1 the following key.
Edit the registry SERVER-1 so only the first-run value remains.
You will need to restart the server.
Take the key and import it on every other server that hosts outlook.
This will be SERVER-2, SERVER-3, etc.
The end result is each server will have the same key and that will match to the signature files.

Good Job Dan.
LegIT Note: You should not install a single user licensed copy on a community server and share it via terminal services. There is a license for that type of application and it's not the retail version license. The above tip is to help those that login as a single user remotely and not to promote more than one person using the single license on a terminal server.
