You can get all the translations associated with the exchange integration with the following statement:

SELECT *

FROM custom_captions

WHERE capt_family = 'exin_syncstatus'

So the code values are:

Failed

InProgress

Interrupt

Success

SuccessW

One thing to bear in mind about the escalation rule. Sometimes, if the tomcat service has an issue, the Exchange integration will not run, and the exin_syncstatus will appear as 'Success' but the last sync time can be a while ago. It may be worth while to build in some logic to look at the last sync time also, so you can be notified if this is significantly greater than the scheduled time.
