How are you accessing Skype for Business Server IM archives post-Teams migration?

[David Phillips]

IM archives are stored in SQL.  Can I decommission my server infrastructure, leave the SQL database online and continue to use the Export-CsArchvingData cmdlet?  Do I need to leave the core components installed on a server to continue to use the cmdlet?  Does a SQL query exist that pulls this data when needed?  Should I just export everything to the .eml format and let the compliance folks sort through it (seems brutal).

The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

Maybe found the answer.  Hope it helps others who might run into the same issue.
