I have two mailboxes attached to Outlook 2010 on my work PC and Outlook 2013 on my personal laptop. For one of these mailboxes I don't wish to see desktop alerts so I have disabled them so that they only show for my main mailbox. This works fine and can be summarised with the following rule description:
Apply this rule after the message arrives
on this computer only
display a Desktop Alert
except through the [email protected]
However, if on an evening away from work I read my email on my laptop, when I arrive back at work the following day I will get an alert for every single email that my work Outlook hasn't seen before regardless of whether it is read or not.
Is there a way to configure my rule so I only see an alert for unread mail? I've looked through all the conditions offered by Outlook for rule conditions and I don't see a way.
