Exchange tasks related to Autodiscover services grows linearly with amount of CAS servers registred in OA. The examples of the tasks are:

"Register domains ... in Autodiscover ..."

"Unregister domains ... in Autodiscover ..."


The issue is caused by software issue with ID POA-97358 ‘Execution time of task "Register domains ... in Autodiscover ..." grows linearly with the number of CAS servers registered in the OA’.


Currently the following workaround can be applied:

  1. Open file "c:\Program Files\Parallels\Windows Provisioning Engine\Providers\SW Managed Exchange\Utils\ExchangeUtils.ps1" on Windows Provsioning Engine node;
  2. Locate function UpdateAutodiscoverConfig;
  3. Comment with # symbol the lines where SynchronizationProvider is called (line numbers 204 and 219);
  4. Save file;
  5. Repeat step 1-4 on all Windows Provisioning Engine hosts.
