Announcing EWSEditor 1.5!

Over the past year I’ve been working with the new Exchange Web Services Managed API and I have to say, it’s a wonderful thing – especially compared to working with the Visual Studio generated proxy classes for Exchange Web Services.  While working with Exchange Web Services (EWS) early in the Exchange 2007 release it became…

EWS: Exchange 2007 RTM vs. SP1 Specifying MeetingTimeZone’s TimeZoneName when creating an Appointment

Prior to Exchange 2007 SP1 an article was published with some specific guidance related to handling time zones in calendar item tasks.  Contrary to Best Practices for Using Exchange Web Services for Calendaring Tasks, specifying just a MeetingTimeZone TimeZoneName when creating a CalendarItem appears to work in Exchange 2007 SP1 and later.  The best practices…


EWS: UID not always the same for orphaned instances of the same meeting.

Earlier I linked to a post by Henning Krauses which discusses searching for a meeting using the UID and GlobalObjectId properties.  The point of UID is to provide a unique identifier for a meeting across the calendars each attendee to the same meeting.  Henning gave some expert advise for using GlobalObjectId instead of UID in…

FYI: DeleteItem behavior, Exchange 2010 SDKs, EWS performance and SyncFolderItems, and Named Property Mapping in Exchnage 2007+

FYI: Can’t use Exchange Impersonation with GetUserOofSettings, SetUserOofSettings, or GetUserAvailability

I kept forgetting about this so maybe blogging it will help me remember.  As this thread confirms – you can’t call GetUserOofSettings, SetUserOofSettings, or GetUserAvailability when using Exchange Impersonation.  If you try to do this you’ll get an error that the Service Account is not the mailbox owner.


Exchange API Team Blog: Exchange Impersonation vs. Delegate Access…

The Exchange API team has a new post to explaining the differences between using Exchange Impersonation vs. Delegate Access to access an Exchange mailbox using Exchange Web Services.  I’ve seen first hand that there is a gap in understanding the difference between the two and when to use one versus the other.  This post goes…

The VSTO team has a post which details an issue that you might see when trying to deploy a VSTO solution to Windows 7 RC.  The error message would be… “The required version of the .NET Framework is not installed on this computer” As the blog post points out, the appropriate teams are aware of…
