+### -DeletedResources
+The DeletedResources parameter specifies the Sharepoint sites to be removed from the list of included sites or excluded from a tenant level policy when the associated group has been deleted. It is used in conjunction with AddModernGroupLocationException and RemoveModernGroupLocation. Valid value is a JSON String.
+
+To specify a deleted resource, you must use the Modern Group mailbox address and the site ID. For example:
+ 
+```powershell
+$stringJson = @"
+[{ 
+     'EmailAddress': '[email protected]', 
+     'SiteId': '9b1a7116-b9ec-4e2c-bf31-4ebb83697c4b' 
+}]
+"@
+```
+
+#### Examples
+To remove deleted modern group (and site) from policy with explicit location:
+```powershell
+Set-RetentionCompliancePolicy -Identity "testModernGroupWithSiteId" -RemoveModernGroupLocation "[email protected]"  -DeletedResources $stringJson
+```
+To exclude deleted modern group (and site) from a tenant level policy:
+```powershell
+ Set-RetentionCompliancePolicy -Identity "testModernGroupWithSiteId" -AddModernGroupLocationException "[email protected]"  -DeletedResources $stringJson
+```
+
+You can enter multiple deleted resources at once separated by commas. 
+```powershell
+ $stringJson = @" 
+ [{ 
+     'EmailAddress': '[email protected]', 
+     'SiteId': '9b1a7116-b9ec-4e2c-bf31-4ebb83697c4b' 
+ }, 
+[{ 
+     'EmailAddress': '[email protected]', 
+     'SiteId': '4nfa7116-b9ec-4e2c-bf31-4ebb83697c4b' 
+ }] 
+ "@ 
+```
