Using Classic Outlook on Windows for personal email, calendar, and contact management
Hi Gregor,
Thank you for posting. When you say "exchange is using suggested contacts", may I know whether you mean Suggested Contacts folder or suggested recipients in the Auto-Complete List?
Generally, we can export contacts from Exchange using Outlook desktop client. You may refer to the article for detailed steps: Export contacts from Outlook
However, as per the article we can no longer add contacts to the Suggested Contacts folder. See under Note
Moreover, if want to export the suggested recipients Auto-Complete List. Here is the article for your reference, see under Copy the AutoComplete list
If anything unclear, please feel free to let us know. We will be glad to help you.
Best regards,
Shyamal
