Creating a new folder in a mailbox if one doesn't exist in WebDav

I posted a script that did this using ADO/Exoledb some time ago here someone asked this week about doing the same thing using WebDAV. In WebDAV to create a folder you use the MKCOL verb eg but if you try and issue this against a URL that already exist then it will throw a 405 error. While dealing with such an error is not that difficult an alternative to doing this is to first do a search against the parent folder to see if that folder exists and then take the appropriate action. A script to do this looks like the following I've posted a downloadable copy here. The script itself looks for a folder called Spamfolder within the inbox if it doesn't find it then it creates it using MKCOL.


server = "Servername"
mailbox = "Mailbox"
NewFLd = "Spamfolder"
strURL = "http://" & server & "/exchange/" & mailbox & "/inbox/"
strQuery = ""
strQuery = strQuery & "SELECT ""http://schemas.microsoft.com/mapi/proptag/x3001001E"""
strQuery = strQuery & " FROM scope('shallow traversal of """
strQuery = strQuery & strURL & """') Where ""DAV:ishidden"" = False AND ""DAV:isfolder"" = True AND "
strQuery = strQuery & """http://schemas.microsoft.com/mapi/proptag/x3001001E"" = '" & NewFLd & "'
"
set req = createobject("microsoft.xmlhttp")
req.open "SEARCH", strURL, false
req.setrequestheader "Content-Type", "text/xml"
req.setRequestHeader "Translate","f"
req.send strQuery
If req.status >= 500 Then
ElseIf req.status = 207 Then
set oResponseDoc = req.responseXML
set oNodeList = oResponseDoc.getElementsByTagName("d:x3001001E")
wscript.echo oNodeList.length
if oNodeList.length <> 0 then
wscript.echo "Folder Already Exists"
else
call Createfolder(NewFld,strURL)
end if
Else
End If

Sub Createfolder(fldname,parentfolder)

nfolderURL = parentfolder & "/" & fldname & "/"
req.open "MKCOL", nfolderURL, false
req.setrequestheader "Content-Type", "text/xml"
req.setRequestHeader "Translate","f"
req.send
if req.status = 201 then
Wscript.echo "Folder created sucessfully"
else
wscript.echo req.status
wscript.echo req.statustext
end if

end sub

Exporting and Uploading Mailbox Items using Exchange Web Services using the new ExportItems and UploadItems operations in Exchange 2010 SP1

Two new EWS Operations ExportItems and UploadItems where introduced in Exchange 2010 SP1 that allowed you to do a number of useful things that where previously not possible using Exchange Web Services. Any object that Exchange stores is basically a collection of properties for example a message object is a collection of Message properties, Recipient properties and Attachment properties with a few meta properties that describe the underlying storage thrown in. Normally when using EWS you can access these properties in a number of a ways eg one example is using the strongly type objects such as emailmessage that presents the underlying properties in an intuitive way that's easy to use. Another way is using Extended Properties to access the underlying properties directly. However previously in EWS there was no method to access every property of a message hence there is no way to export or import an item and maintain full fidelity of every property on that item (you could export the...

The MailboxConcurrency limit and using Batching in the Microsoft Graph API

If your getting an error such as Application is over its MailboxConcurrency limit while using the Microsoft Graph API this post may help you understand why. Background   The Mailbox  concurrency limit when your using the Graph API is 4 as per https://docs.microsoft.com/en-us/graph/throttling#outlook-service-limits . This is evaluated for each app ID and mailbox combination so this means you can have different apps running under the same credentials and the poor behavior of one won't cause the other to be throttled. If you compared that to EWS you could have up to 27 concurrent connections but they are shared across all apps on a first come first served basis. Batching Batching in the Graph API is a way of combining multiple requests into a single HTTP request. Batching in the Exchange Mail API's EWS and MAPI has been around for a long time and its common, for email Apps to process large numbers of smaller items for a variety of reasons.  Batching in the Gr...

Sending a Message in Exchange Online via REST from an Arduino MKR1000

This is part 2 of my MKR1000 article, in this previous post  I looked at sending a Message via EWS using Basic Authentication.  In this Post I'll look at using the new Outlook REST API  which requires using OAuth authentication to get an Access Token. The prerequisites for this sketch are the same as in the other post with the addition of the ArduinoJson library  https://github.com/bblanchon/ArduinoJson  which is used to parse the Authentication Results to extract the Access Token. Also the SSL certificates for the login.windows.net  and outlook.office365.com need to be uploaded to the devices using the wifi101 Firmware updater. To use Token Authentication you need to register an Application in Azure https://msdn.microsoft.com/en-us/office/office365/howto/add-common-consent-manually  with the Mail.Send permission. The application should be a Native Client app that use the Out of Band Callback urn:ietf:wg:oauth:2.0:oob. You ...
