Base Expiry of Archives set to Modification Date.

Hello Again,

Scenario:

1. Base expiry set to Modified Date.

2. Archiving of "UnRead" items is Enabled.

3. UnRead email item gets archived & replaced with a shortcut. (Shortcut displayed in Bold letters)

4. User now clicks on THIS UnRead shortcut item. (Shortcut NOT displayed in Bold anymore)

5. Action 4 will result in the Exchange Jet Database to flag this item as "read" and hence the item in exchange is NOW "Modified"

Question:

Will the expiry of this item be calculated from the day it was read?

How does Enterprise Vault deal with such modification flags set in Exchange?

Thanks in advance.
