The AzureADAuthorizationEndpointUri parameter specifies the Azure AD Authorization endpoint Uri that can issue OAuth2 access tokens.

• For Exchange Online PowerShell in Office 365 Germany, use the value https://login.microsoftonline.de/common for this parameter.

• For Exchange Online PowerShell in Microsoft 365 GCC High and Microsoft 365 DoD, use the value https://login.microsoftonline.us/common for this parameter.

To connect to other Exchange PowerShell environments (for example, Security & Compliance Center PowerShell or standalone Exchange Online Protection PowerShell), use this parameter with the Connect-IPPSSession cmdlet.

The BypassMailboxAnchoring switch bypasses the use of the mailbox anchoring hint. You don't need to specify a value with this switch.

The ConnectionUri parameter specifies the connection endpoint for the remote PowerShell session.

• For Exchange Online PowerShell in Office 365 Germany, use the value https://outlook.office.de/PowerShell-LiveID for this parameter.

• For Exchange Online PowerShell in Microsoft 365 GCC High, use the value https://outlook.office365.us/powershell-liveid for this parameter.

• For Exchange Online PowerShell in Microsoft 365 DoD, use the value https://webmail.apps.mil/powershell-liveid for this parameter.

To connect to other Exchange PowerShell environments (for example, Security & Compliance Center PowerShell or standalone Exchange Online Protection PowerShell), use this parameter with the Connect-IPPSSession cmdlet.

The Credential parameter specifies the username and password that's used to run this command. Typically, you use this parameter in scripts or when you need to provide different credentials that have the required permissions.

A value for this parameter requires the Get-Credential cmdlet. To pause this command and receive a prompt for credentials, use the value (Get-Credential). Or, before you run this command, store the credentials in a variable (for example, $cred = Get-Credential) and then use the variable name ($cred) for this parameter. For more information, see Get-Credential.

The DelegatedOrganization parameter specifies the customer organization that you want to manage (for example, contosoelectronics.onmicrosoft.com). This parameter only works if the customer organization has agreed to your delegated management via the CSP program.

After you successfully authenticate, the cmdlets in this session are mapped to the customer organization, and all operations in this session are done on the customer organization.

The EnableErrorReporting switch enables logging errors to a local file. You don't need to specify a value with this switch.

By default, it creates 2 files in the %TMP% folder. You can use the LogDirectoryPath parameter to specify the location of the log files.

The ExchangeEnvironmentName specifies the Exchange Online environment. Valid values are:

• O365China

• O365Default (this is the default value)

• O365GermanyCloud

• O365USGovDoD

• O365USGovGCCHigh

The LogDirectoryPath parameter specifies the location of the log files. The default location is %TMP%\EXOCmdletTelemetry\EXOCmdletTelemetry-yyyymmdd-hhmmss.csv.

If you specify a custom location and filename that contains spaces, enclose the value in quotation marks (").

The LogLevel parameter specifies the logging level. Possible values are Default and All.

The PSSessionOption parameter specifies the PowerShell session options to use in your connection to Exchange Online. You store the output of the New-PSSessionOption command in a variable, for example:

$Options = New-PSSessionOption <Settings>

And you use the variable name as the value for this parameter (for example, $Options).

The PageSize parameter specifies the maximum number of entries per page. Valid input for this parameter is an integer between 1 and 5000. The default value is 1000.

The Prefix parameter specifies an alias to add to nouns in the names of older remote PowerShell cmdlets (cmdlet with nouns that don't already start with EXO). A valid value is a text string without spaces, and you can't use the value EXO (this prefix is reserved for PowerShell V2 module cmdlets).

The ShowBanner switch shows or hides the banner message that's displayed when you run Connect-ExchangeOnline. You don't need to specify a value with this switch.

To show the banner, you don't need to use this switch (the banner is displayed by default).

To hide the banner, use this exact syntax: -ShowBanner:$false.

The ShowProgress parameter shows a visual progress bar in the PowerShell client module. The progress bar shows number of objects received and total number of objects requested. Valid values are:
