Good Day,

We have two Microsoft Office 365 Index Servers configured in a load-balanced setup.

The index disk on Index Server A became full, so I ran the Load Balance Index Server workflow. After the workflow completed, the index data was moved/copied from Index Server A to Index Server B.

Since then, we have been experiencing issues accessing the Index Server and index-related operations are no longer functioning correctly.

Could you please clarify:

  1. Why are the Microsoft Office 365 backup indexes not automatically distributed across both Index Servers when load balancing is configured?
  2. What is the recommended method to rebuild or recover the indexes after running the Load Balance Index Server workflow?
  3. How can we restore normal Index Server operation in this scenario?

We are running on SP 11.40.67
