It depends what you have based your expiry on...if it's based on modified date the item will be expired immediately once you run storage expiry, if storage expiry is set to archived date then the item will not be expired until 2 years since it was archived have passed.
Base Expiry on:
Modified date: Items in archives expire at the end of the Retention
Period. When you select Modified date, the start of the Retention Period
is calculated as follows:
For mail messages, this is the time since the message was received.
For documents, it is the time since the document was last modified.
Archived date: Items in archives
expire at the end of the Retention Period.
When you select archived date, the start of
the Retention Period is the date the items
were archived. This setting is useful if
you import old items from other mail systems.
If the items are very old and deleted items
expire on sent/received date, then the items could expire immediately.
