Quickly import emails
We would like to move all the email from an email box that we have been using into servicedesk plus for consolidation and archival purposes as we transition into using the product in place of a shared mailbox. The problem i am running into is that the mailbox has 40,000+ items in the inbox to import and it will only pull in 20 items at a time and check only once a minute.. So at this rate it will take almost 34 hours to import the mailbox.
Is there any way to more quickly import these messages or speed up the mail fetching?
