This was more than a patch this time. It was a minor update to two functions:
There was an issue reported (#12) where the sendMailItem function was not working in IE11. This was because it was created to take an inline object (ES6). Well on IE11 (which only supports ES5), it broke.
So, I fixed sendMailItem to support ES5 and also took the opportunity to add two often requested features of this function:
It will now allow you to submit HTML body content or Text. It will also parse the HTML for you if you submit it as is.
It will also now allow you to send both file attachment (new), and mail item attachments (original).
Also I updated the sendPlainTextEmailWithAttachment function. Under the covers this uses the sendMailItem function. So I had to update it to use the new format so it would work as well. There was no change to it’s features/functionality however.
I did not get to the last item I have had requests for:
ability to specify recipients as To/CC/BCC. I will update this at some future date. Also, please let me know if you would like to see this.
Overall, the goal is to have the sendMailItem() function be a full multi-purpose function at some point. It is almost there, but please keep the suggestions coming.
There is one major change and one fix in this update:
The library no longer has any dependencies on jQuery. As such all parsing is done with DOMParser and all loops are traditional (for, versus $.each()).
NOTE: This is a fairly major change as it touches the core asyncEws call, which is at the very core over every call in the library. If you have an issue with this build, please point to the previous build of the library directly. See more below…
The sendPlainTextEmailWithAttachment() function was fixed to submit parameters as a Object versus individually.
The GitHub repository has all previous versions. For example, to access the primary CDN, go to:
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.
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.
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.
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.
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:
<?xml version="1.0" encoding="utf-8"?>
<!– Note: EwsEditor has replaced the "utf-16" text in the first line with"utf-8" in order for the XML to render in the response web control. –>
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.
