Syncing of contacts between iphone and Outlook PC

I just did a big cleanup on my contacts on my PC from Outlook (Office 365). I’m using Air Sync

which is activated. On my PC, I now have outlook 0 contacts and iCloud 714

contacts. On my iPhone 11 running ios 17.7.1, I have all contacts 1734; all iCloud

838; on Outlook folder on iPhone, I have all Outlook 909, contacts 2, iPhone

(contacts) 907. Sync is apparently not deleting iCloud contacts on the iPhone

which are deleted in Outlook. How to resolve this? Thanks.
