Hi All, In Microsoft 365 Defender "Restricted Users" now called "Restricted Entities", because it can also detect and create an alarm for a compromised Connector https://security.microsoft.com/restrictedentities Respond to a compromised connector https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/respond-compromised-connector?view=o365-worldwide Regards Andres Bohren

Good Morning, I've had a customer that encountered the Error below during Exchange 2016 CU23 installation. Error: The following error was generated when "$error.Clear(); Install-ExchangeCertificate -services IIS -DomainController $RoleDomainController if ($RoleIsDatacenter -ne $true -And $RoleIsPartnerHosted -ne $true) { Install-AuthCertificate -DomainController $RoleDomainController } " was run: "System.Security.Cryptography.CryptographicException: The certificate is expired. at Microsoft.Exchange.Configuration.Tasks.Task.ThrowError(Exception exception, ErrorCategory errorCategory, Object target, String helpUrl) at Microsoft.Exchange.Management.SystemConfigurationTasks.InstallExchangeCertificate.InternalProcessRecord() at Microsoft.Exchange.Configuration.Tasks.Task.<ProcessRecord>b__91_1() at Microsoft.Exchange.Configuration.Tasks.Task.InvokeRetryableFunc(String funcName, Action func, Boolean terminatePipelineIfFailed)".

Hi All, I recently had a customer that wanted to write an Application to read the Availability (Free/Busy) from the Calendars of theyr users.Here is how you can do that with Microsoft Graph. First you need an Application in Azure Active Directory with an AppID / ClientID Then you need to be able to Authenticate. I usually use a Certificate for that purpose. As for the Permissions, the Application needs the following: App needs Application Permissions:

Hi All, Since a few weeks i had a strange behavior with the "Get-Place" command. I knew it has worked before. I did get an Error only on a newly created CloudOnly Mailbox it worked. Get-Mailbox -RecipientTypeDetails RoomMailbox Get-Mailbox -RecipientTypeDetails RoomMailbox | Get-Place With the ExchangeOnlineManagement 2.0.6 Preview6 Module it worked perfectly fine I did open a Microsoft Case and the support guided me to Microsoft Graph GET https://graph.microsoft.com/v1.0/places/microsoft.graph.room To get a specific Mailbox use this URL GET https://graph.

Hi All, I was digging a little bit deeper into the Recipient Management without Exchange Server. I've already blogged about it how to install the Managment Tools only fo install the Recipient Management PowerShell Install and use Exchange 2019 CU12 Recipient Management PowerShell https://blog.icewolf.ch/archive/2022/04/27/install-and-use-exchange-2019-cu12-recipient-management-powershell.aspx Add-PSSnapin *RecipientManagement Get-PSSnapin As you can see on the Server the Exchange Server 2019 CU12 is installed (Management Tools only) I found the References of the PowerShell Snapins in the Registry here: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapins

Hi All, A Month ago, Microsoft annouced in the Exchange Team Blog, the New Reply-all Storm Protection Report, Settings UI and new Mail flow Alert Policies. New Reply-all Storm Protection Report, Settings UI, and Alert Policy https://techcommunity.microsoft.com/t5/exchange-team-blog/new-reply-all-storm-protection-report-settings-ui-and-alert/ba-p/3292465 In the new Exchange Admin Center https://admin.exchange.microsoft.com you can find the Reply-all Storm Settings unter Settings > Mail flow These Settings can also be configured by PowerShell. Keep in Mind, that the Minimum Recipients must be between 1000 and 5000.

Hi All, I've tried out the ExchangeOnlineManagement Preview6 PowerShell Module ExchangeOnlineManagement 2.0.6-Preview6 https://www.powershellgallery.com/packages/ExchangeOnlineManagement/2.0.6-Preview6 Get-InstalledModule ExchangeOnlineManagement Find-Module ExchangeOnlineManagement Installing the Module Side by Side Install-Module ExchangeOnlineManagement -AllowPrerelease -Force Connect-ExchangeOnline As you can see, there is no PS Session Get-PSSession Get-Mailbox -Identity a.bohren@icewolf.ch | fl Name Get-EXOMailbox -Identity a.bohren@icewolf.ch | fl Name If you check the Commands it seems pretty complete Get-Module Get-Command -Module ExchangeOnlineManagement | measure Get-Command -Module tmpEXO* | measure

Hi All, Maybe you have noticed the new Mail flow Alert policies in Exchange Admin Center. You can define new Alert policies, define the Severity, the Insight, the recipient, the Notification Limit and sometimes also the Threshold for the Alert.

Hi All, Recently i stumbled over a funny Error. When query the Get-TenantAllowBlockListItems all looks fine until you connect to Security and Compliance (Connect-IPPSession). You will then see even Watson Error Messages 😂 I am using ExchangeOnlineManagement PowerShell Module Version 2.0.5. Had a Case open: 30305990 - The Engineering Team is now aware. And will hopefully fix it in a future Version of the PowerShell Module. Manage the Tenant Allow/Block List

Hi All, Microsoft works since a while at "One Outlook", a simplified Outlook Client based on OWA. There has been a leak from an early Version and i've downloaded and installed it.
