End users using OWA on Exchange 2013 CU5. Doesn't matter what browser or any other client-side information. I can give myself delegate access to various mailboxes and come up with the same error.
They compose a new message. Type the name in the To.. field and the application pops the drop-down with the magnifying glass that reads "Search Contacts & Directory". When you click, it states in the same box "Can't connect. Please try again later."
Troubleshooting steps, thus far:
- Recycle OWA Application Pools.
- Recycle ECP Application Pools.
- Recycle OAB Application Pools (yes, I know, this is for Outlook only).
- Restart all CAS servers.
Nothing works. Has anyone else seen this and found a fix for it? It has to be something simple that I am missing.
