Skype for Business is one of the main communication channels within a corporate environment.

Organizations very often require changing the password, and sometimes there might be replication or latency issues which create a mismatch with the credentials stored.

To fix the issue, in many cases, you will need to clear the cache.

The most common reason to clear the cache include:

  • Dial pad missing
  • You cannot log in on Skype for Business
  • You cannot search for users in Skype for Business
  • Your contact list is out of date
