GDPR for Skype for Business Server and Lync Server
Most Skype for Business Server and Lync Server data is stored in Exchange Server. This includes:
Conversation history
Voicemail notifications and transcriptions
Meeting invites
Use the procedures outlined for GDPR for Exchange Server to find, export, or delete these types of data for GDPR requests.
Contact lists are stored in the SQL Server database. They can be exported in the following ways:
End users themselves can export the contacts by right clicking the group header and selecting Copy. This will copy all the contacts in that group into the clipboard, which can then be pasted into any app.
You can use the Export-CsUserData cmdlet to export this data.
Content uploaded into meetings (such as PowerPoint files or handouts) or content generated in a meeting (such as whiteboard, polls, or Q/A) is stored in the filer. This can also be exported if end users log back into any meeting that hasn't expired and download any uploaded content or take screenshots in the case of generated content.
MeetNow meetings that aren't in the Exchange Calendar and Contact List and contact rights (family, co-worker, etc.) are in the User Database. In Lync Server 2013 and later, you can use the Export-CsUserData cmdlet to export this data.
