EV10 Index Synchronise Task

Hi,

I have enabled a new mailbox for archiving and imported a few items. The new items do not show in the archive, and the index status shows as "not yet created" and there is no folder under the Index location.

I get an event 41352 in the event log, below, when attempting to synchronise the index.

The processing of the Synchronize Sub task has stopped following errors.

Description: Failed to Get Next IndexLocation: [1DB250FE1B7ABBB409214D8277327FC1F1110000evarca-ap1-01_9485].

The Rebuild and Verify tasks complete successfully, but still no items show and still no index folder.

I have tried to create the folder manually, no difference.

I can't find anything relating to this error.

Any ideas?
