If Add2Outlook was working and now it's not, post here.
We we're using Add2Exchange before on our premise Exchange Servers but recently switched to Office 365.
So now we are using Add2Outlook, but we are getting this error frequently.
Synchronization with your <ActiveSync device> failed for 1 items.
We are getting this on all replication relationships (contacts)
When we delete the item from our contacts at the next sync, the items is copied again and a sync later we are getting this error back...
Recreating the Contact in the Public folder is not helping. We've tried it, but that didn't help either.
Does anybody got a clue what could be wrong?
