Thanks chanchan05 for the reply.
I can import/sync any one of the Directories I have in Outlook/Contacts on my PC to the HTC phone, and they go into "Phonebook" as it doesn’t seem possible to import/sync them directly into a Group.
At this stage all Groups are empty.
I can then bulk copy (but not move) all of these contacts to a Group (lets say Group A).
The Contacts in Phonebook remain the same.
Now at this point, if I import/sync another Directory from Outlook with a view to putting its Contacts into another Group (say Group B) the imported/synced Contacts go into the existing Phonebook Directory where they are mixed alphabetically with those already there.
So to create Group B I would have to transfer them one by one.
If I delete all the Contacts in the Phonebook Directory, (to clear it ready to sync another Outlook Contacts Directory,) then the Contacts in Group are deleted too.
What is needed is a Phonebook that offers more than one Directory (customisable)
Hence my wondering if there is a suitable App, though I haven’t found one.
I hope this clarifies my question.
