I've been able to bulk remove by using the MFCMAPI tool, if the OLK profile is set up as Exchange or Exchange Online (not sure if it'll work with IMAP protocol).
PROCEED WITH CAUTION. THIS TOOL IS NOT MEANT FOR NON-TECHNICAL USERS.
- Make sure that you enable the MDB_ONLINE and MAPI_NO_CACHE boxes through Tools before starting.
Look for Top of Information Store/Contacts/Companies/Outlook Customer Manager if you wish to clear out Companies for the user.
XrmProjects/Deals folder will contain the Deals for the profile if you wish to remove all deals as well.
The Contacts themselves should be removable through the People pane in OLK 2016, but if they're not deleting then you can remove through Top of Info Store/Contacts/Outlook Customer Manager as well.
Hope this helps.
