Description

Tip

The output of the Get-OrganizationConfig cmdlet often shows curly braces or {} around properties values that accept multiple comma-separated values. Don't use those extra characters in values for the corresponding parameters on this cmdlet. Use the syntax as explained in the parameter descriptions.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Set-OrganizationConfig -DistributionGroupDefaultOU Users\Groups -DistributionGroupNameBlockedWordsList curse,bad,offensive -DistributionGroupNamingPolicy "DL_<GroupName>_<Department><CountryCode>"

This example creates a distribution group naming policy using the following configuration:

Distribution groups will be created in the Users\Groups container.

The words curse, bad, and offensive will be blocked from being used in distribution group names.

All distribution groups will be prefixed with DL_ and suffixed with an underscore (_) and the user's department and country code.

Example 2

Set-OrganizationConfig -EwsApplicationAccessPolicy EnforceBlockList -EwsBlockList $null

This example allows all client applications to use REST and EWS.

Example 3

Set-OrganizationConfig -EwsApplicationAccessPolicy EnforceBlockList -EwsBlockList "OtherApps*"

This example allows all client applications to use REST and EWS, except those that are specified by the EwsBlockList parameter.

Example 4

Set-OrganizationConfig -EwsApplicationAccessPolicy EnforceAllowList -EwsAllowList $null

This example prevents all client applications from using REST and EWS.

Example 5

Set-OrganizationConfig -EwsApplicationAccessPolicy EnforceAllowList -EwsAllowList "CorpApp*"

This example allows only the client applications specified by the EwsAllowList parameter to use REST and EWS.

Example 6

Set-OrganizationConfig -VisibleMeetingUpdateProperties "Location,Subject,Body,AllProperties:15"

In Exchange Online, this example results in meeting updates being auto-processed (meeting update messages aren't visible in attendee Inbox folders) except any changes to meeting location, subject and body as well as any property changes within 15 minutes of the meeting start time.
