‘Autodiscover service couldn’t be located’ when trying to access Exchange 2010 account with EWS MANAGED API

Reading e-mails from Outlook with Python through MAPI

I had the same problem you did – didn’t find much that worked. The following code, however, works like a charm. import win32com.client outlook = win32com.client.Dispatch(“Outlook.Application”).GetNamespace(“MAPI”) inbox = outlook.GetDefaultFolder(6) # “6” refers to the index of a folder – in this case, # the inbox. You can change that number to reference # any other … Read more

Publishing Outlook Calendars. What is the server-side setting for sync frequency?

Retrieve calendar items (Outlook API, WebDAV) displaying strange behaviour

Possible cause: Sort after setting IncludeRecurrences. Here is my code of a PowerShell module that retrieves Outlook items between two dates. And a little applet to check for changes and send an email including the agenda updates, which comes handy when you don’t have mobile access to the Exchange. Path: Documents\WindowsPowerShell\Modules\Outlook\expcal.ps1 Function Get-OutlookCalendar { <# … Read more

EWS API – Error when recreating notification subscriptions

Given the documentation at: https://msdn.microsoft.com/en-us/library/office/dn458788(v=exchg.150).aspx When a subscription is lost, or is no longer accessible, it is best to create a new subscription and not include the old watermark in the new subscription. Resubscribing with the old watermark causes a linear scan for events, which is costly. Instead, create a new subscription and compare folder … Read more

Read MS Exchange email in C#

It’s a mess. MAPI or CDO via a .NET interop DLL is officially unsupported by Microsoft–it will appear to work fine, but there are problems with memory leaks due to their differing memory models. You could use CDOEX, but that only works on the Exchange server itself, not remotely; useless. You could interop with Outlook, … Read more
