Hi Csound1,
I am stogling with the same issue posted on this discussion.
Exchange2013 and raw contacts populated on my contacts as well as on the exchange server (I have seeing it using a PC and outlook).
You sugest to clean on My Mac contacts. Do not set on My Mac as a default account. Following is what I found:
There is no way to get out the on My Mac account from contacts.
There is no way set any default account on contacts>preferences>general
The on My Mac contacts list IS EMPTY and the '-' sign is hidden on the contacts>preferences>accounts.
When I turn on my Exchange Account on my contacts are downloaded from the server, however, I still not able to set ANY DEFAULT ACCOUNT at all.
If I leave like it is 2 days later I will have at least a dozen of those expurious emails on my contacts list.
Thanks,
Edson
