Error
Inconsistent get item response (0 items returned but more are available).
Cause
This error occurs when the Source server is overloaded and MigrationWiz is unable to get consistent responses from the Exchange server. To prevent additional issues, MigrationWiz stops the migration.
Resolution
To resolve this issue, investigate the health of the source server to reduce the server load and minimize the number of concurrent migrations.
This error can also occur because the number of items in a single folder is quite large, and causes the Source server to return only partial responses.
If this error persists, using the Advanced Support option DisableEWSDataConsistencyCheck=1 will bypass the consistency check but may result in missing items.
