since some days my Voicemail Icon is missing.This step doesn't work:Exit Skype for Business and Outlook client.
Navigate to Users > username > AppData > Local > Microsoft > Office > 16.0 > Lync
Delete sip_profileName folder.
Delete all files in Tracing folder. Do not delete the folder itself.
Login to Skype for Business again.
Thanks + Regards
