public List<ItemId> DeleteItems(
	IEnumerable<ItemId> ids
)

Public Function DeleteItems ( 
	ids As IEnumerable(Of ItemId)
) As List(Of ItemId)

Parameters

ids

Type: System.Collections.GenericIEnumerableItemId
The IDs of the items to delete. Null reference (Nothing in Visual Basic) not allowed.

Return Value

The item is deleted using DeleteMethod mode.

If you have a collection of EwsItem objects, you can convert it into the collection of ItemId elements using EwsItemsToItemIds(IEnumerableEwsItem) method which you can then pass to the current method.

Note
This method can still complete successfully if at least one item has been deleted. To make sure all the requested items have been deleted, check that the length of the resulting list is the same as the count of elements in the input. ItemId values of the items which could not be deleted will not be present in the resuling list.

Note
This method is not implemented in .NET Core. Use DeleteItemsAsync(IEnumerableItemId) instead.
