Will people be able to have their address books moved to the new platform?
Yes this will be possible, we aim to have more information over the next day or so
Will they be able to retrieve a copy of their address books (if so what format will it be)?
This may be in the format of squirrel mail contacts, again more info as we have it.
Will people be able to ensure addresses have been removed by PlusNet from all internal systems and backups.
We have a data retention and disposal policy that ensures data is destroyed before disposing of media and that we do not hold data for longer than is necessary.
Why this seemingly wasn't thought of before moving to the new platform?
It was thought of, however the priority was to get a webmail solution back up for customers.
I suppose it may be a good time to put in a suggestion to have full import/export features available for address books.
This may be looked at in the future but there are other things required first.
