Voicemail not showing up on Lync / Skype for Business Client

The Voicemail to UM enabled users are not appearing under the voicemail option of Phone Tab in Lync /SfB Client. It forced users to listen to their voicemail via outlook. The issue was most probably due to corrupt a UM profile and Lync cached.
The issue has been resolved through the following steps:

• Disable User UM on Exchange Server
• Exit Lync
• Delete Lync Cache
• Access this path and delete all folders. 

This path will be different depending on your OS and the client.

• “C:\Users\ABC12345\AppData\Local\Microsoft\Communicator\sip_UseremailID@mydomain.com”
• Delete Tracing Contents
• Access this path and delete all files “C:\Users\ABC12345\Tracing\”
• Open Outlook and Select Voice Mail Folder under Search Folder and Delete
• Disable Exchange Cached Mode from Outlook setting
• Close Outlook
• Enable User's UM on UM server
• Open Outlook and allow some time to sync - A new Voice Mail will be created under Search Folders
• Open Lync Client and allow some time to Sync
• Check Voicemails under the voicemail option of Phone Tab in Lync/SfB Client.
