Scripting with OMA - Outlook Mobile Access

Continuing on from some of my other posts about using the Microsoft.XMLHTTP object to do some automation scripting with OWA I've started at looking at doing this in OMA as well. OMA is a lot less feature rich environment because it's designed for mobile devices but from a automation perspective this can be an advantage. There's very little information out there that covers how OMA work's from an indepth technical perspective (well that I could find anyway). But the basics of it is that its a ASP .NET application and from the reverse engineering I've looked at it passes some tokens and GUID looking parameters to make it work. As a starter script I created a simple script that uses the Microsoft.XMLHTTP object to list the contents of the inbox using OMA. Unlike OWA where you can just post a single command to the IIS server with OMA I found it required two requests. The first request logs onto OMA and gets the front page and more importantly a little token (the ufps thingy) that you must send with the post request to get it to work. I found you can specify your own GUID and this seems to work okay I guess as long as you are not using multiple clients with the same GUID. The only trick I found is that you must specify authentication in your open statement. I also haven't worked out how to target a mailbox other then the authentication user.

szXml = ""
Set ObjxmlHttp = CreateObject("Microsoft.XMLHTTP")
ObjxmlHttp.Open "get", "http://server/oma/(cvlbrraeffpq1xu5c013j055)/oma.aspx?", False, "domain\user", "password"
ObjxmlHttp.setRequestHeader "Accept-Language:", "en-us"
ObjxmlHttp.setRequestHeader "Content-type:", "application/x-www-UTF8-encoded"
ObjxmlHttp.setRequestHeader "Content-Length:", Len(xmlstr)
ObjxmlHttp.Send szXml
Wscript.echo ObjxmlHttp.responseText
slen = instr(ObjxmlHttp.responseText,"ufps") + 5
ufps = mid(ObjxmlHttp.responseText,slen,6)
szXml = "__EVENTTARGET=c00&__EVENTARGUMENT=c0&__V_ViewStateKey=0"
ostring = "http://server/oma/(cvlbrraeffpq1xu5c013j055)/oma.aspx?__ufps=" & ufps
ObjxmlHttp.Open "post",ostring , False, "domain\user", "password"
ObjxmlHttp.setRequestHeader "Accept-Language:", "en-us"
ObjxmlHttp.setRequestHeader "Content-type:", "application/x-www-form-urlencoded"
ObjxmlHttp.setRequestHeader "Referer:", "http://server/oma/(cvlbrraeffpq1xu5c013j055)/oma.aspx"
ObjxmlHttp.setRequestHeader "Content-Length:", Len(szXml)
ObjxmlHttp.Send szXml
Wscript.echo ObjxmlHttp.responseText

Export calendar Items to a CSV file using EWS and Powershell

Somebody asked about this last week and while I have a lot of EWS scripts that do access the Calendar I didn't have a simple example that just exported a list of the Calendar events with relevant information to a CSV file so here it is.

I've talked on this one before in this howto  but when you query the calendar folder using EWS you need to use a CalendarView which will expand any recurring appointments in a calendar. There are some limits when you use a calendarview in that you can only return a maximum of 2 years of appointments at a time and paging will limit the max number of items to 1000 per call. So if you have a calendar with a very large number of appointments you need to break your query into small date time blocks. In this example script I'm just grabbing the next 7 days of appointments if you want to query a longer period you need to adjust the following lines (keeping in mind what I just mentioned)

#Define Date to Query
$StartDate = (Get-Date)
$EndDate = (Ge…

EWS Managed API and Powershell How-To series Part 1

I thought I'd start the year with a series of posts that goes back over the basics of using the EWS Managed API from Powershell and provides a modular remarked example that you can easily cut and paste to build your own scripts. Along the way in this series I'll show a whole bunch of examples around specific things.

As a starting point for versions this will be Powershell Version 2.0  and the EWS Managed API 1.1 (which will soon change to 1.2 once released)

The starting point for any EWS script your going to write is connecting to Exchange for which there are three important pieces of information you will need. Firstly you need to know the version of Exchange your running in this script its going to be held in the following variable

$ExchangeVersion = [Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2010_SP1

Other valid values for Exchange 2007 would be

$ExchangeVersion = [Microsoft.Exchange.WebServices.…

Writing a simple scripted process to download attachmentts in Exchange 2007/ 2010 using the EWS Managed API

Every complicated thing in life is made up of smaller simpler building blocks, when it comes to writing a script (or any code really) the more of these little building blocks you have to figure out the more the process of solving a problem can become bewildering. The Internet generally provides you with lots of half eaten sandwiches of information something someone else has taken a bite out but a lot of the time half done, and as with any code its usefulness declines over time as new and better API's and methods are derived. In this post I'm going to go through a simple scripted process that hopefully covers a few more of these smaller building blocks that you might face when asked to come up with a simple costless solution to perform an automated business function with a script.

So the process im going to look at is one that comes up a lot and that is you have an Email that comes into to certain mailbox every day with a certain subject in my case "Daily Export" this …
