I migrated 10 users from Exchange on a SBS 2011 server to a hosted Exchange 2016 solution. Everything went smoothly using MFCMAPI from http://mfcmapi.codeplex.com
to export the autocomplete list to .msg except on 2 Windows 10 machines running Office 2013. I exported the autocomplete msg from every machine on the network before the migration and these two didn't work. When I import the exported autocomplete msg file, it doesn't show up in the list and, of course, doesn't re-populate the autocomplete. These two PCs have in common that they were using roaming profiles. I have gone back to the old server with another computer, allowed the roaming profile to configure itself, exported the autocomplete msg again, copied it to a test PC so I don't keep disturbing the end user, and it behaves the same on the new machine, so it's not the PCs, there's something about those two files or that tool just can't export data from roaming profiles.
I'm stumped and any help is appreciated.
