The replicators for Exact Online, Microsoft CRM, Microsoft EWS, and Salesforce fail.
Checking possible causes
Check the Windows Event Viewer to see if EIComContactReplicator.exe crashed.
The following error message appears in the MetaDirectory log files: ReplicatorManagerQueue;Replicator reported an unknown error: C0000005.
We have worked out the following workaround for this issue:
Replace the EIComContactReplicator.exe with the file from version 5.0.7. You can find it here: EIComContactReplicator.zip.
After downloading the file, go to the MetaDirectory installation directory (default: C:\Program Files\estos\MetaDirectory) and replace the file there.
