easyEws v1.0.16 Published

I have made a few minor updates to easyEws. First, was a fix for distribution lists with an “&” in the name. The second is a few minor JSDoc updates for better linting. And finally, I changed a couple forEach loops to traditional for loops for performance reasons.

I have published the update to NPM and to my GitHub.

Please let me know if you have any issues or questions.

easyEws v1.0.15 Released

In this latest release I have incorporated my first community pull. A big thank you to Vijay Samtani for adding the sendMailItem. This new addition allows you to create a message to multiple recipients and with zero to many attachments.

Here is a link to the repository: https://github.com/davecra/easyEWS

You can references it in your code:

And you can allow pull it down from NPM:

npm install easyEws

easyEws v1.0.14 released

First off, there is no version 1.0.13. wlEmoticon-winkingsmile.png

For this latest release, I have added one handy new function getParentId(). This function uses the child message “InReplyTo” field to locate the parent message with the same corresponding “InternetMessageId” field. If found, you will get the Id of that parent message. If not found, you will get NULL.

As per usual, to get the latest you can link to the CDN: https://cdn.jsdelivr.net/gh/davecra/easyEws/easyEws.js

Or you can access it from NPM via this command:

npm -install easyews

NOTE: I was informed that I had forgot to update NPM to v1.0.12 per the last release. So I have fixed that and have updated this build on NPM.

easyEws v1.0.12 released

I have updated the easyEws library.

The changes I made in v1.0.11 for ResolveNames were only ES6 compliant and did not work in IE11. Specifically, I defined an ES6 class object versus a more compliant ES3+ function/class. The update was recoded and now functions in IE11.

Additionally, there was a reported issue with recipient aggregation in the getallRecipientsAsync() function. I was using a .forEach() on the recipient array which seemed to be causing problems with larger result sets. So I updated it to use a standard for loop.

Other than that there were no major changes to this version.

easyEws Updated to v1.0.11

It has been a while since I have updated this library, however I have had a few requests.

The first one that I am publishing today is adding the ResolveNames operation. The latest is now on GitHub here. And you can install it using NPM like this:

npm install easyews

Also, I have updated the CDN listing. Before I was using RAWGIT but that has been retired. You can now add the CDN like this:

To issue a resolve names you will pass the email address or the display name to the function like this:

If you have any suggestions for this library, please ping me.

Expanding Personal Contact Lists in Outlook with OfficeJS

If you are developing an OfficeJS add-in for Outlook or Outlook Online (OWA) and your project requirements have a need to peek inside distribution lists, you might find that there are two kinds:

  • Distribution Lists – these are Exchange groups, or mail enabled Active Directory groups. These are managed by the enterprise IT and contain a list of email addresses and/or other distributions lists.
  • Contact Lists / Private Distribution Lists – these are personal lists created by the user that can contain similar objects.

For an Office Add-in, you must use the makeEwsRequestAsync() command to submit EWS to Exchange. And the specific command you will need to use is ExpandDL to get the members of a DL (or contact list). With regards to the first item in the list above, it is pretty straight forward. For the second item there is this blurb on the page:

Private distribution lists are located in the Contacts folder of a user’s mailbox. Private distribution lists do not have e-mail addresses so their store item identifiers are used in an ExpandDL request. Members of a private distribution list can be any mail-enabled user, contacts or distribution lists from Active Directory, or contacts or private distribution lists from a user’s Contacts folder.

The bold part is key. But where do you get this. When you request a to.getAsync() and receive “Bob’s Favorite People” as a recipient item what do you do with it?

The key is to call the EWS method ResolveNames. When you call this on “Bob’s Favorite People” you will get a return value with PrivateDL and an ItemID (the Exchange Store Item ID in the users Contact folder) that you will then send that ItemId to ExpandDL. Here is what the soap response would look like from ResolveNames:

You can then make your ExpandDL request like this:

The result will be a list of all the email addresses, like this:

NOTE: For now the ResolveNames operation is not supported in my library easyEws. I am working to add it in the coming weeks.

Please let me know if you have any suggestions or questions.

NOTE: I am not an Exchange Web Services (EWS) expert, but have some experience with it through the OfficeJS makeEwsRequestAsync() command. To get the answer for this blog entry, I had to go to a real EWS expert to figure this one out. Many thanks to Dan Bagley (EwsEditor) for his assistance.

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”
