Default Calendar permission Powershell GUI for Exchange 2010 SP1 and up

One of the new cmdlets in Exchange 2010 SP1 is the Set-MailboxFolderPermission cmdlet which was an addition to the other Exchange 2010 RTM folder permission cmdlets get-MailboxFolderPermission and add-MailboxFolderPermission. What this cmdlet gives you the ability to do is update the permissions of any folder within a mailbox as long as you are a member of the RBAC roles that allows you set them as specified in http://technet.microsoft.com/en-us/library/dd638132.aspx. Another thing this cmdlet does is give me the ability to revisit the default calendar folder permission GUI from this post(which used EWS and will still work okay on 2010) and rewrite this to be able to be used in Remote powershell so it will work against any 2010 SP1 server as well as anything else that supports these cmdlets such as live@edu or Office365.

If you don't really want a GUI and would rather just export the permissions to CSV modify them and then reimport them that's easy to do for example to export the settings to a csv file.

$rptCollection = @()
$mailboxes = get-mailbox -ResultSize Unlimited
$mailboxes | foreach-object{
$alias = $_.alias + ":\Calendar"
$displayName = $_.DisplayName
write-host $alias
$permissions = Get-MailboxFolderPermission $alias | Where-Object {$_.Identity.ToString() -eq "Default"}
if($permissions -ne $null){
$stringPerms = ""
foreach($perms in $permissions.AccessRights){$stringPerms = $stringPerms + $perms + " "}
Add-Member -InputObject $permissions -MemberType NoteProperty -Name "Alias" -Value $alias -Force
Add-Member -InputObject $permissions -MemberType NoteProperty -Name "StringAccessRights" -Value $stringPerms -Force
$rptCollection += $permissions
}

}
$rptCollection | export-csv -notypeInformation c:\defaultperms.csv

To then re-import them from a csv file you can use

import-csv c:\defaultperms.csv | foreach-object{
"Seting Rights on " + $_.alias
Set-MailboxFolderPermission -id $_.alias -User $_.Identity -AccessRights $_.StringAccessRights

}

Personally i like the GUI which is a little more snappier with the GUI I left the permission descriptions in Outlook format rather then switching them to the accessrights role format(the great thing about standards is there are so many to choose from). To run this GUI you need to first start a Remote powershell session and import the Exchange 2010 cmdlets or run it directly from within the EMS. I've put a download of the new script here the code looks like

$displayName = $_.DisplayName
write-host $alias
$permissions = Get-MailboxFolderPermission $alias | Where-Object {$_.Identity.ToString() -eq "Default"}
if($permissions -ne $null){
Add-Member -InputObject $permissions -MemberType NoteProperty -Name "Alias" -Value $alias -Force
$stringPerms = ""
foreach($perms in $permissions.AccessRights){$stringPerms = $stringPerms + $perms + " "}
$logTable.rows.add($displayName,$permissions.alias,$stringPerms)

The MailboxConcurrency limit and using Batching in the Microsoft Graph API

If your getting an error such as Application is over its MailboxConcurrency limit while using the Microsoft Graph API this post may help you understand why. Background   The Mailbox  concurrency limit when your using the Graph API is 4 as per https://docs.microsoft.com/en-us/graph/throttling#outlook-service-limits . This is evaluated for each app ID and mailbox combination so this means you can have different apps running under the same credentials and the poor behavior of one won't cause the other to be throttled. If you compared that to EWS you could have up to 27 concurrent connections but they are shared across all apps on a first come first served basis. Batching Batching in the Graph API is a way of combining multiple requests into a single HTTP request. Batching in the Exchange Mail API's EWS and MAPI has been around for a long time and its common, for email Apps to process large numbers of smaller items for a variety of reasons.  Batching in the Gr...

Sending a Message in Exchange Online via REST from an Arduino MKR1000

This is part 2 of my MKR1000 article, in this previous post  I looked at sending a Message via EWS using Basic Authentication.  In this Post I'll look at using the new Outlook REST API  which requires using OAuth authentication to get an Access Token. The prerequisites for this sketch are the same as in the other post with the addition of the ArduinoJson library  https://github.com/bblanchon/ArduinoJson  which is used to parse the Authentication Results to extract the Access Token. Also the SSL certificates for the login.windows.net  and outlook.office365.com need to be uploaded to the devices using the wifi101 Firmware updater. To use Token Authentication you need to register an Application in Azure https://msdn.microsoft.com/en-us/office/office365/howto/add-common-consent-manually  with the Mail.Send permission. The application should be a Native Client app that use the Out of Band Callback urn:ietf:wg:oauth:2.0:oob. You ...

How to test SMTP using Opportunistic TLS with Powershell and grab the public certificate a SMTP server is using

Most email services these day employ Opportunistic TLS when trying to send Messages which means that wherever possible the Messages will be encrypted rather then the plain text legacy of SMTP.  This method was defined in RFC 3207 "SMTP Service Extension for Secure SMTP over Transport Layer Security" and  there's a quite a good explanation of Opportunistic TLS on Wikipedia  https://en.wikipedia.org/wiki/Opportunistic_TLS .  This is used for both Server to Server (eg MTA to MTA) and Client to server (Eg a Message client like Outlook which acts as a MSA) the later being generally Authenticated. Basically it allows you to have a normal plain text SMTP conversation that is then upgraded to TLS using the STARTTLS verb. Not all servers will support this verb so if its not supported then a message is just sent as Plain text. TLS relies on PKI certificates and the administrative issue s that come around certificate management like expired certificates which is why ...
