[Resolved] – “Server time out error while using AddListMembersListRequest” D365 CRM

Many of us would have used AddListMembersListRequest to add members to marketing list via plugins, workflows, batch jobs etc. Are you aware that there was an issue reported on April 2019. If you are trying to add 5000 records in 2 minutes CRM platform throws server time out error. We raised support ticket with Microsoft on the same front. Ticket ID “119040323001150“.

According to them, their is a deadlock error in SQL causing this issue.

Finally, this has been fixed by Microsoft. There is no max limit that Microsoft has provided/committed, but as per my test results you can add 3.5 lac members in one go with service proxy time out being set to 10 minutes.
