Glen's Exchange and Office 365 Dev Blog

One of the scripts that I posted that seems to have a steady stream of input is the EWSContacts Module I put up some time ago. Thanks to  Friedrich Weinmann  who did some recent cleanup of the module on GitHub it is now looking a lot neater. After a recent question from somebody I've made some more changes to the  Export-EXCContactFolder function to allow you to if your exporting a Public Folder or a mailbox's Contacts Folder to recurse any subfolders of that folder you passed in and export those contacts also. When this option is selected a field is added to the CSV to tell you which MailboxFolder (or PublicFolder) the contact was exported from. To use this new feature when exporting contacts from a Public folder just use the recurse switch eg Export-EXCContactFolder -PublicFolderPath "\Office Contacts" -Recurse -MailboxName gscales@datarumble.com -FileName c:\temp\alc2.csv Another parameter I've added is the -RecurseMailbox which will instead of startin...

Pinning email is a new feature that is available in OWA(or Outlook on the Web) on Office365 and Exchange 2016 and a much requested feature in Outlook  https://outlook.uservoice.com/forums/322590-outlook-2016-for-windows/suggestions/12963459-pin-or-stick-important-emails-at-the-top-of-your-I What happens when you pin an Email in OWA is it sets two MAPI properties on the backend when pinned the value will look like the following the value 1/9/4500 is significant and is used when an Item in Pinned in the UI, When the Item is Unpinned in the UI 0x0F01 reverts back the current time and  0x0F02 is removed from the item. So in EWS if you want to display all the Pinned email you can use a SearchFilter to filter the Item based on the value of this property eg  $PR_RenewTime2 = new-object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition(0xF02,[Microsoft.Exchange.WebServices.Data.MapiPropertyType]::SystemTime);  $SfSearchFilter = new-object Microsoft...

As I've been adding new cmdlets to my Exch-REST PowerShell module I've been knocking up against some of the limitations and frustrations of working within a console environment. One of them is if say I find some Messages within a Mailbox which needs further investigation for whatever reason, It good to have an easy way of opening up that message to take a look at the content that isn't normally easy to view in the cmdline like the html body of a message and maybe I want to download any attachments or MessageHeaders without needing to open Outlook or OWA. A number of years ago I created a simple EWS mail client that just acted as a simple Email client using EWS so I decided to port this to the REST API and include it in the Exch-Rest Module. I also broke out two of the winforms from this simple client to enable just reading a particular Message you may have found using any of the other cmldets as well as a simple Form to Send a New Message with or without an Attachment. ...

As I had a few questions about exporting contacts to CSV from both Mailbox and Public folders I've added some new functions to the my EWS contacts module to make this easier.  I've added to new cmdlets the first is Export-ContactsFolderToCSV This will export a contacts folder to CSV's either the default Contacts Folder in a Mailbox or a secondary Contacts folder if you enter in the FolderPath eg to export the Default contacts Folder use Export-ContactsFolderToCSV - MailboxName user@domain.com -FileName c:\exports\contacts.csv To export a Secondary Contacts Folder use Export-ContactsFolderToCSV - MailboxName user@domain.com -FileName c:\exports\contacts.csv -Folder \Contacts\SecondContactsFolder Export-PublicFolderContactsFolderToCSV This will export a Public Contacts Folder to a CSV file to use this use Export-PublicFolderContactsFolderToCSV -MailboxName mailbox@domain.com -FileName c:\exports\PublicFolderexport.csv -PublicFolderPath \folder\folder2\contact...

One of the recurring questions you see asked in Forums around EWS is the ability to see all the Room Mailboxes in Exchange. This is pretty reasonable request that hasn't really had an easy answer in the past there are RoomLists but these required setup and ongoing maintenance and coordination  which can be troublesome. If you where using OnPrem exchange then instead of using EWS you could just use LDAP to lookup Active Directory directly (as well all know AD is the directory service for Exchange) eg back in 2007 I created this http://gsexdev.blogspot.com.au/2007/04/webservice-to-find-room-and-equipment.html . With Office365 you don't have LDAP access to the directory and the Graph API while its good doesn't offer access to the particular property on a User or Directory Object that would allow you to tell if that object has an associated Room (or group or shared mailbox). The good news however is the Graph API  now gives you the ability to pull all the Room Mailbox using f...

When it comes to Messaging API's there no more complex thing then calendaring, not only because most vendors implement things a little differently but Exchange also has a little legacy feature drag because of its length of time in the market place and the difficulties in changing the technology and human interaction with it. The new REST API offers yet another window into calendaring on Office 365 and Exchange 2016 with a major security benefit over its predecessor which is the ability to be able to scope your application access so it can only access the Calendar folders in a Mailbox where previously apps may have needed to have Full Rights or impersonation rights on a Calendar. Also the new REST API allows you to interact with Group Calendars (or Teams Calendar) so leveraging the new REST API to value add to the adoption of these new features can be a worth your while. To Support Calendaring I've added 2 new cmdlets to the Exch-Rest module to handle creating Appointments and...

Outlook and OWA allow you to create "Favorites" shortcuts to Public folders (and other folders for that matter) to make accessing them a faster experience. For those of us keeping pace with grinding Public Folders into dust (personally no longer a fan) and replacing them with Groups, it maybe useful to report on which Public Folders people have Favorited in their mailboxes for a metric and impact point of view. This information should then come in useful if your planing on migrating them (or just for a laugh). Because Public folder hierarchies are relatively complex having the path to the Public folder rather then just the name is generally a lot more useful. So in the script in this blog post we will look at producing a report of the Public Folder favorites and the Path of the Public Folders those shortcuts refer to eg it will produce a report something like the following for each mailbox you where to run it against. Like other mailbox shortcuts these favorites ar...
