easyEws v1.0.10 Released

In this release I have incorporated two new functions to help with recipients (To/CC/BCC) and groups/distribution lists:

  • getAllRecipientsAsync() – helps you by getting all the unique recipients on the To/CC/BCC lines. It returns two lists in the callback:
    • A list of standard users
    • A list of groups
  • splitGroupsAsync() – accepts an array of groups (or Distribution Groups) and expands them to a unique set of users.

I have also corrected a few small bugs, like one with MailBoxUser (where Address was incorrectly JSDoc’d as Email).

I have also included a minified version of the library. So you can access easyEws.min.js in your code to reduce the download.

You can access it from:


Updated Outlook Web Add-in Sample

I will be presenting a demo at the MVP Summit 2018 for Outlook and also helping with some labs in Excel on the OfficeJS platform. In preparation, I updated my Outlook Sample on my GitHub. This sample was created in VSCode via a Yeoman template.

What the add-in does is a check of all users on the To/CC/BCC line, splits apart any groups (or groups in groups) and then checks to see if any of the user emails are external to your domain. If any external users are found it prompts you with dialog asking if you are sure you want to send:

Outlook Blocking Add-in

The updated add-in demonstrates:

  • The OnSend event
  • The use of dialogs
  • And the newly added ExpandDL function for Exchange Web Services through the makeEwsRequestAsync() call.

In this sample, I am using both of my libraries:

  • easyEws – to help with the ExpandDL call. Updated in a previous post.
  • OfficeJS.dialogs – to display the dialog you see above.

I also had to create a set of asynchronous functions and asynchronous recursive function calls to perform this work – which got a tad complex. For now all the code is in the function-file.js, but to help with splitting out all recipients and groups I might build this into a new library. For example, here is the function to recursively call itself asynchronously (splitting groups in groups in groups in groups…):

Anyway, I will be demonstrating this add-in and the functionality required at the MVP Summit. So if you are attending, I hope to see you there.

easyEws v1.0.9 Released

With recent changes to Exchange Online, the ExpandDL functionality has been added to the makeEwsRequestAsync function. As such this function, which was previously “advertised” in easyEws (but marked as **DO NOT USE**), now functions as designed.

To use the new function:

NOTE: AS of this writing (2/27/2018), this is NOT supported in Exchange 2016 (on-prem). It is to be released with CU9.

The update is posted to GitHub here: https://github.com/davecra/easyEWS.

You can also get v1.0.9 via NPM with the command: “npm update easyews”

Outlook Email Reporting Sample

I just posted a new Outlook sample on GitHub. I have created something very similar to this sample for a couple of customers now and have been using this as a template. What this sample does is place a button on the Ribbon for users to report suspicious email to the administrator. The user will get the option to select why they think it is suspicious as well as provide a comment. When they click Send, it will email the administrator. The email address which receives this notification is configured in the URL for the add-in page via the manifest XML.

Anyway, I wanted to share this basic sample with the community so others can use this to quickly implement similar solutions in their environment.

All the details for configuring the add-in are in the README.md. Here is the link the new sample: https://github.com/davecra/Outlook.ReportAddin. I also created this in VS Code.

Please let me know if you have any questions or suggestions for other samples you would like to see.

OfficeJS.dialogs version 1.0.8

I have recently updated the OfficeJS.dialogs to version 1.0.8. I have also updated the Node Package Manager version as well. You can get it by running the following command in the VSCode Terminal Window:

npm install officejs.dialogs

With this latest version comes a few bug fixes, some cleanup of the code, cleaner JSDoc documentation and a PrintPreview dialog. The PrintPreview started out as a proof of concept but it actually works for me – in the browser anyway. I am not sure how well it will work in any of the full clients as I have not tested it there yet. If anyone has a chance to test it, please let me know if you encounter any issues.

Here is a sample of the PrintPreview dialog:


Here is some code to implement it:


easyEws v1.0.7 is now released

This has been slow coming, but I have just released v1.0.7 of easyEws. As per usual, it is on NPM and on GitHub. You can get the latest with the command:

npm update easyews

Or, you can install it into your solution with the command:

npm install easyews

In this version the JSDOC information is now full incorporated so you get great inline help with each command. I enhanced the library so that it works better with inline help and so I changed how the class is setup and exposed. I have updated the README.md on GitHub, but I still am working on examples and such, that will be done later. And I added new functionality, a moveItem command which can be used to move any item from one folder to another. This was a added due to feedback I received on LinkedIn.

Please feel free to reach out to me with any questions or suggestions.
