I was using this guide to switch the service account:
BlackBerry Search Results
Ran into problem in task 11.
When trying to change the MAPI profile to BESAdmin, it kept saying could not resolve name.
Could not keep BB server down for more than 30min so I put the service log on back to admin.
doing more research on this issue.
unchecked hide this address from addressbook and I was able to change the MAPI profile. Did some tests but could not get any messages on the phone nor look up any address from the phone.
Do I have to reinstall the server using theh BESadmin account?
