"System.ArgumentOutOfRangeException: index is out of range." exception is raised while saving an item with ItemAttachment

[rsrini83]

Hi,

I'm trying to save an item in Exchange online into a folder (Inside Inbox), this item has ItemAttachment added. Seems item is being saved to the server properly, however client code throws below exception.

Here is the code to add ItemAttachment,

                        ItemAttachment<EmailMessage> attachment = eMessage.Attachments.AddItemAttachment<EmailMessage>();
                        attachment.ContentType = ewsAttachment.ContentType;
                        attachment.IsInline = ewsAttachment.IsInline;
                        attachment.Name = ewsAttachment.Name;
                        ExtendedPropertyDefinition PR_Flags = new ExtendedPropertyDefinition(3591, MapiPropertyType.Integer);
                        attachment.Item.SetExtendedProperty(PR_Flags, "1");
                        attachment.Item.MimeContent = new MimeContent("UTF-8", Convert.FromBase64String(ewsAttachment.Base64));

ewsAttachment -> is our own model which contains the attachment in Base64.

After further debugging, identified the failing scenario.

This issue is happening If there is a FileAttachment in the ItemAttachment.

If attaching an email message(without any attachment) as ItemAttachment then there is no issue.

Anyone faced the issue? I'm stuck here, any help would be greatly appreciated.

When you say "ewsAttachment -> is our own model which contains the attachment in Base64.", how are you getting this base64? And you say that this is happens when you attach this file attachment on an item attachment which is on an item, right? What happens if you try to attach this file attachment (via the MIME content) directly to an item?

[rsrini83]

Hi David,

how are you getting this base64 ? Download the ItemAttachment using MIME content and convert it to base64.

Let me give an example,

Assume i'm downloading mailitem1 -> which has an itemattachment mailitem2(EmailMessage). mailitem2 has a file attachment. In this scenario i'm getting the index error. However if mailitem2 does not have any attachment then there is no issue.

What happens if you try to attach this file attachment (via the MIME content) directly to an item? It works, however i need to attach mail item as is.

[davster]

Thanks for the info. I'll see if I can repro on my side and if so open a bug to fix it.

[rsrini83]

Sure. Let me know if you need any sample eml, can create one and send you.

[rsrini83]

Hello David,

Are you able to reproduce the issue? Any suggestion to resolve the issue?

[shooddelta]

I am having this same problem.

I am using the API to copy and email from one exchange server then send it on a different one (for internal use) If the email I am trying to copy has a file attachment in the mime content then I error out when I try to send it.

Did you ever come up with a solution to your issue?

Did this issue ever got solved? I am facing the exact same problem and I'm stuck!

Is there any workaround for this?

[GeoffreyYue1]

The exception is because of response in 2013 schema like below:

NoError

this.Count will be 0 after read the first attachment element.

Resolved by edit the ComplexPropertyCollection.cs, add "&& this.Count>0" when dealing with complexproperty.

///

/// Loads from XML to update itself. ///

/// The reader. /// The XML namespace. /// Name of the XML element. internal override void UpdateFromXml( EwsServiceXmlReader reader, XmlNamespace xmlNamespace, string xmlElementName) { reader.EnsureCurrentNodeIsStartElement(xmlNamespace, xmlElementName);

        if (!reader.IsEmptyElement)
        {
            int index = 0;
            do
            {
              
                reader.Read();

                if (reader.IsStartElement() && this.Count>0)
                {
                    TComplexProperty complexProperty = this.CreateComplexProperty(reader.LocalName);
                    TComplexProperty actualComplexProperty = this[index++];

                    if (complexProperty == null || !complexProperty.GetType().IsInstanceOfType(actualComplexProperty))
                    {
                        throw new ServiceLocalException(Strings.PropertyTypeIncompatibleWhenUpdatingCollection);
                    }

                    actualComplexProperty.UpdateFromXml(reader, xmlNamespace, reader.LocalName);
                }
            }
            while (!reader.IsEndElement(xmlNamespace, xmlElementName) );
        }
    }

@tallalkazmi @shooddelta @rsrini83 for my purpose, i workarounded successfully by adding the item as a FileAttachment:

//assume item = the EmailMessage to attach, message = the EmailMessage to attach to PropertySet psPropSet = new PropertySet(BasePropertySet.FirstClassProperties); psPropSet.Add(ItemSchema.MimeContent); var tmpItem = EmailMessage.Bind(context, item.Id); tmpItem.Load(psPropSet); message.Attachments.AddFileAttachment(item.Subject + ".eml", tmpItem.MimeContent.Content);

beware that this will not copy all outlook properties, e.g. Categories, which was no problem in my scenario.

I was also having this problem, when I was attaching an Email Item (with file attachments) as an Item Attachment, to a new email, which I was trying to create in an Inbox folder of other mailbox. Solution from @GeoffreyYue1 worked for me too.

[HenryLehloo]

I am having the same issue as well. I'm new to this and how do I implement @GeoffreyYue1 solution? Where do I find ComplexPropertyCollection.cs, im using EWS.

You actually have to download the entire source code, compile in Visual Studio 2017 or 2019, and then search the file 'ComplexPropertyCollection.cs', which resides in the sub folder '\ews-managed-api-master\ComplexProperties'.

Then, you would have to change line number 162 from if (reader.IsStartElement()) to if (reader.IsStartElement() && this.Count > 0)

I can provide you modified Ews DLL with the fix (which I built) if you want. Thanks

[HenryLehloo]

@laeeq can you please provide the DLL, thank you very much.

I am experiencing the same issue as well. I wish this would get addressed in an updated version.

I will roll with @GeoffreyYue1 's fix.
