Automated Outlook Signature Scripts
This project contains two scripts:
- GenerateSignature.ps1 - Used to generate and set a user's signature for desktop Outlook
- Set-OutlookWebSignatures.ps1 - Used to gen
Outlook desktop signature script currently tested on and working with Outlook 2010, 2016 and 2019. Outlook web signature script has been tested on Exchange Online.
The Scripts
This is a very basic description on how to use the scripts and how they work. For more detail please see the YouTube videos linked earlier
Desktop Signature Script
Video guide: https://www.youtube.com/watch?v=rt9y02iBoPE
I recommend using the script in Group Policy as a log-on script. If you are unaware of how to do this rather than reinvent the wheel explain here I shall point you to this article :) - Configuring Logon PowerShell Scripts with Group Policy - 4Sysops
During logon the the script is ran, gets the details for the user, creates a new signature file and replaces their current one. It also sets registry keys to configure this signature as their default Outlook signature. These means if their job title etc. has changed their signature will be kept up to date at next logon.
Exchange Online Signature Script
Video guide: Coming soon Currently this script can be ran manually from a device which has both the ActiveDirectory module and the ExchangeOnlineManagement module. It checks for all users in a particular security group, in the example currently in the script that group is called "Outlook Web Signature" and for all the users in there it creates a .html file in a specific folder. If the file doesn't already exist or is different it will add that user to a list of users who need their signature updated. Once this step is complete, if there are any signatures to update the script will prompt you for credentials to connect to Exchange Online and will use the require html files to update the specific signatures. This avoids all mailboxes getting new signatures each time it is ran.
