Please be advised that I have tried ABF Outlook backup and also another app called BackupOutlook. Neither worked for me, let me tell you why.
I use an Exchange server for my main email account. This restricts me to having all email received ending up in the Exchange amilbox even for additional POP3 accounts. I also have about 20 pop3 accounts which are legacy and due to me having moved around alot in life and therefore using different ISP's meant I endded up changing my email address often. POP3 accounts in my Outlook profile must have the Echange Mailbox as their final delivery point.
Neither of the above products works with this setup. BackupOutlook simply does not recreate teh Exchange account only the POP3 accounts. ABF simply wont give you the option to backup the Profile. BackuOutlook claim it does work ABF do not and I am still trying to get my refund from BackupOutlook despite their "satisfaction garantee".
Most of these apps provide a limited demo which does not let you test these all important things without buying so I suggest you DONT buy them.
