Access Rights Manager Issue With Exchange Server Discovery and Scans

Dear ARM community, 

Microsoft released the security update for Microsoft Exchange Server KB5001779 on April 13 to increase the security of Exchange Server installations. 

KB5001779 is known to be part of the cumulative updates (CU) 

  • Exchange 2013 CU23 
  • Exchange 2016 CU19, CU20 
  • Exchange 2019 CU8, CU9 

Unfortunately, the changes applied also affect third-party software like ARM connecting to Exchange Server 2013, 2016, or 2019. 

We are working on a solution for this issue with the highest priority!
