There's a old saying that a tradesmen is only as good as their tools and the same can be said for ITPro's and developers. You can save yourself a lot of time when investigating particular tasks you want a script by having something ready built that can do 90% of task at hand.  I've decided to share a script that I use quite often during the investigation phase of any EWS scripting tasks that allows you to generically grab a folder (or collection of Folders) and the Items within those folder. While this is something that can be put together quite quickly together using snippets there always tends to be extra properties that you need for different tasks so the generic script I'm showing today includes all the niceties kind of like having the right sized spanner rather the shifter. So the script in question can be found on GitHub here  https://github.com/gscales/Powershell-Scripts/blob/master/GenericFolderAndItem.ps1 So what can it do Connect and show the properties ...

Auto-mapping was a feature that was introduced in Exchange 2010, where when you added Mailbox access permission via Add-MailboxPermission, Outlook would automatically add that Mailbox as an additional Mailbox. Outlook uses Autodiscover to get the information on these mailboxes that are auto mapped via the AlternateMailboxes user setting eg in XML it comes back like the following One thing you can't see easily via the Exchange Managed Shell cmdlet is which ACE's (Access Control Entries) have Automapping enabled on a particular Mailboxes DACL and which don't. You also can't easily see from one mailbox which mailboxes will be auto mapped to it (basically a reverse mapping).So the purpose of this script is to provide both a forward and reverse mapping of Automapping setting for a collection of Mailboxes that are passed into to. It produces a report that look like To get this collection you can either use a CSV file of addresses, Get-Mailbox or just a sta...

If you ever have the need to create a number of events in user mailbox's from a central application or Script where the target Mailboxes span across different time zones then finding each target Mailbox's timezone is a critical thing. In this post I'm going to outline a few different methods of getting the TimeZone using EWS. If you have access to the Exchange Management Shell cmdlet's to find the users configured timezone you can use either the Get-MailboxCalendarConfiguration or Get-MailboxRegionalConfiguration cmdlets which show you the timezone settings of a Mailbox from the WorkHours configuration of that mailbox. The object in the Mailbox that the information is read from/stored in is the IPM.Configuration.WorkHours FAI (Folder Assoicated Items) object in the Calendar Folder of the Mailbox. So if you want to access the TimeZone setting in Mailbox just using EWS you need to Bind to this UserConfiguration object (FAI object) and th...

I've done a few of these Unread / Unused mailbox scripts over the years but this one has a bit of a difference. As well as counting the Total number of unread email in the Inbox over a certain period of time it uses the PidTagLastVerbExecuted property to count how many email messages over that period of time had the client action ReplytoSender, ReplyAll or forwarded and also the number of email in the SentItems folder. This property is set on messages in the Inbox message when one of those actions is taken by the client so it is useful for tracking the use of Mailboxes and gathering statistics around how they are being used. eg here are a few samples of running this module The code uses both EWS and the Exchange Management Shell to get information about the Mailbox so you need to run it from within the EMS or a Remote PowerShell session (see this if your running it from Office365). I've put the script up on GitHub or you can download it from here . I've...

In Outlook and OWA when you are using the Multiple calendar view feature you can assign different colors to calendars within that view. (By default the calendar color is set to automatic which means a color is assigned at random) eg When you add a Shared Calendar to your Mailbox you create a Calendar WunderBar Navigational shortcut which are documented https://msdn.microsoft.com/en-us/library/ee202589(v=exchg.80).aspx  . The color that these shortcuts will be set to is set via the PidTagWlinkCalendarColor property https://msdn.microsoft.com/en-us/library/ee200641(v=exchg.80).aspx  . So if you want to set the color of one of these shortcuts with a script it does require a little bit of work. First to get the shortcut Items you need to first get the CommonViews folder and then enumerate the FAI Items collection where these shortcuts are stored. Now depending if you want to the Set the Default Folder Shortcut or a Shared Folder Shortcut (or the other calendars Shortcu...
