Sophos Secure Mail syncing Contacts that were deleted in Outlook

Hello,

one of our employees deleted alot of his contacts from Outlook (which were in different folders before), but Sophos still has all of the contacts and folders in the "contacts" thus when tapping on "all contacts" he has some of the contacts 2-4 times.

I even uninstalled und unregistered all of the Sophos Apps to completly re-register him in the Sophos Console, but it still has all the folders with contacts from his Outlook.

Renewing the Database in the Email App itself didn't help either and now I am kind of lost.

Got another short question: Is it somehow possible to access the contacts with the cars bluetooth device, without transfering the business contacts to the phone ?

best regards
