Unable to perform search from OWA and Outlook in Online mode



When doing a search in OWA you get …Microsoft Exchange Search unavailable" error bar.

Event Log Error” msexchange search index event id 103 and 104

When you run Test-ExchangeSearch -Identity "Username" and it returns a value of -1 indicates search is not working

Steps to resolve (each is a dedicated step that may resolve)

  1. Reinstall the Exchange Search service from programs and features
  2. From Powershell Run "ResetSearchIndex.ps1 [-force] -all" to rebuild indexes
  3. Manually re-create catalog http://technet.microsoft.com/en-us/library/aa995966(EXCHG.80).aspx
  4. Re-register the DLL “Regsvr32 C:\Program Files\Microsoft\Exchange Server\Bin\MapiProtocolHandlerStub.dll”

Note: Some wait time may be needed when indexing starts before full index and search are complete.
