We are currently migrating from Exchange 2010 SP3 Rollup 9 to a fresh install of Exchange 2013 CU8 (installed directly from the CU). Mailbox moves are running smoothly and both Exchange version Mailboxes are accessible by clients during migrations.

However, under OWA 2013's People -> Directory (Address Lists), proper selection of the listed addresses failed.

1. Attempt to select an item under Directory will result in a multiple (Ctrl+Select) selection behaviour. Re-clicking the selected item will not unselect it.
2. The same issue is also exhibited when adding addresses (clicking + plus sign in the To or CC box) during Mail compose.
3. This behaviour only affects the Directory Address Lists; it does not affect selection behaviour of Personal Contacts items or any other Mailbox items such as Mails or Tasks.
4. We have tried IE 11.0.9600.17801, Firefox 27.0.2 and Chrome 42.0.2311.135 but the above issue persists.
5. Only affects Listings (all items) under Directory; when "Search People" results are displayed, selection behaviour is working.
6. Only affects OWA web interface; does not affect Microsoft Outlook or any other GAL behaviour.

During initial loading of the People page (All Rooms were selected onLoad), we noticed two XHR POST requests were made from the OWA to the FE:

1. /owa/service.svc?action=FindPeople&ID=-36&AC=1

This request received a 200 success response with the following JSON:

{"Header":{"ServerVersionInfo":{"MajorVersion":15,"MinorVersion":0,"MajorBuildNumber":1076,"MinorBuildNumber":9,"Version":"V2_22"}},"Body":{"ResponseCode":"NoError","ResponseClass":"Success","FirstLoadedRowIndex":0,"FirstMatchingRowIndex":0,"ResultSet":[{"PersonaId":{"Id":"AQUQAAAP"},"PersonaTypeString":"Unknown","CreationTimeString":"0001-01-02T08:00:00+08:00","DisplayName":"xxxx","DisplayNameFirstLast":"xxxx, BPTM","DisplayNameLastFirst":"xxxxx","FileAs":"","RelevanceScore":2147483647},{yyyy},{zzzz}],"TotalNumberOfPeopleInView":8}}

*xxxx, yyyy and zzzz are obfuscated items.

2. /owa/service.svc?action=GetPersona&ID=-37&AC=1

This request also received a 200 success response with the following JSON:

{"Header":{"ServerVersionInfo":{"MajorVersion":15,"MinorVersion":0,"MajorBuildNumber":1076,"MinorBuildNumber":9,"Version":"V2_22"}},"Body":{"MessageText":"Active Directory operation did not succeed. Try again later.","ResponseCode":"ErrorADOperation","ResponseClass":"Error","Persona":null}}

When the All Distribution Lists were selected, the following XHR POST were registered:

1. /owa/service.svc?action=GetGroupInfo&ID=-50&AC=1

This request received an error 500 response with the following JSON:
