Hi,
yes there is.
We do not support the proprietary protocol called MAPI used by Microsoft Exchange and/or Office 365,
but for it you can still use POP3/SMTP protocol that it's fully available.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
