Skype for Mac Update Breaks Skype Directory Service, Here’s How You Can Fix It

Some macOS & iOS users are complaining about an annoying bug on the Microsoft Skype app that restricts them from finding new contacts. It seems to be a serious issue with the Skype Directory which was caused by the latest Skype for Mac Update.

A number of furious users highlighted the issue on the Microsoft Answers forum. According to a Skype user, the issue persists across different platforms.

“I am trying to find a new contact in Skype, but It is not working and I am unable to find any contact.I have tested Skype for Mac 8.54.0.91, Skype for iPhone and Skype web, all of them are not finding contacts. Any solution?”

Another Skype user reported that the issue exists on two different iMacs.

“Same issue here – I am unable to find anyone that is not already in my contacts.I have tried 2 different iMacs on different wired and wireless networks and my iPhone on wifi and 4G. I can’t connect to any new contacts. All machines running latest version of Skype.”

The Skype Customer Support team confirmed the bug on the Microsoft Community forum. The good news is, Microsoft has already investigated the issue and it was caused by a new security update released by Apple.

We have been able to identify that this incident is the result of a new security update in the Apple system that invalidates the Microsoft certificate for the server responsible for said service.

Skype team is currently working to resolve the Skype Directory service issue. However, Microsoft has suggested a quick workaround to help you fix the issue.
