Hello,

I have very weird situation reported by multiple customers (some of them are returning with this problem). Basically in webmail clients see not their contacts. Solution for this problem is to add new contact and everything is returning to normal (old contacts reappear and not user contacts are gone).

I've downloaded CSV file from clients contacts using impersonate while he had someone else contacts, added new contact and downloaded CSV contacts file from webmail again. They are completely different.

Based on not users contacts CSV file I've started to search for one of them agains other domains folder-*.json files and I found one mailbox.

My observations:

Does someone experienced similar issue?

Thanks
