Hello Tanya Vandermaat

It is mentioned here that you could try Exchange Online Shell.

Hi Tanya Vandermaat,

The error you're encountering while trying to set up a Dynamic Distribution List (DDL) in Microsoft Exchange seems to be related to an incorrect or incompatible value being used in the process.

Problem:
Issue with Value '1': The error message indicates an attempt to set a property (likely IncludedRecipients) with the value '1', which isn't recognized. In the context of Dynamic Distribution Groups, IncludedRecipients it is typically set to a specific recipient type like 'MailboxUsers,' 'MailContacts,' etc.

Possible Solution
Check the Value of IncludedRecipients: Ensure that you're using a valid value for the IncludedRecipients property. It should be a string corresponding to a recipient type understood by Exchange, like 'MailboxUsers,' 'MailContacts,' 'MailGroups,' etc., not a numeric value like '1'.

All the best

I'm getting the same error no matter what I select, there seems to be an issue on MS end. Here is my error;

Can't set Microsoft.Exchange.Management.RecipientTasks.NewDynamicDistributionGroup with value 1 with either direct assignment or parse: Microsoft.Exchange.Admin.OData.Core.ODataServiceException: Attempt to set IncludedRecipients as enum value failed: Failed to locate flag enum string '1' in the type 'WellKnownRecipientType' at Microsoft.Exchange.AdminApi.PSDirectInvokeProvider.PSDirectInvokeProvider1.HandleEnumValue(String propertyName, Type targetEnumType, String incomingRawValue) at Microsoft.Exchange.AdminApi.PSDirectInvokeProvider.PSDirectInvokeProvider1.SetParameterValue(PropertyInfo property, Object obj, Object value) System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.Exchange.AdminApi.PSDirectInvokeProvider.PSDirectInvokeProvider`1.SetParameterValue(PropertyInfo property, Object obj, Object value).

Answer 4

Same problem here - and there is no place I personally did or can set the value '1' (which isn't recognized). This needs a better explanation.

Answer 5

Same problem here using admin.exchange.microsoft.com: attempting to create a Dynamic Distribution List fails miserably with:
Can't set Microsoft.Exchange.Management.RecipientTasks.NewDynamicDistributionGroup with value -1 with either direct assignment or parse: Microsoft.Exchange.Admin.OData.Core.ODataServiceException: Attempt to set IncludedRecipients as enum value failed: Failed to locate flag enum string '-1' in the type 'WellKnownRecipientType' at Microsoft.Exchange.AdminApi.PSDirectInvokeProvider.PSDirectInvokeProvider1.HandleEnumValue(String propertyName, Type targetEnumType, String incomingRawValue) at Microsoft.Exchange.AdminApi.PSDirectInvokeProvider.PSDirectInvokeProvider1.SetParameterValue(PropertyInfo property, Object obj, Object value) System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.Exchange.AdminApi.PSDirectInvokeProvider.PSDirectInvokeProvider`1.SetParameterValue(PropertyInfo property, Object obj, Object value).
