Any antivirus software must be configured to not scan the Migrator for Notes to Exchange program files directory or %temp% directory, or may be simply turned off, but may be restored after the program runs. If an antivirus scan misinterprets an Migrator for Notes to Exchange temporary file as a threat, it will try to "clean" the file, and the SSDM program call would then fail.
ASP.net version 4.5 must be installed. If the SSDM Scheduling Web Service is running, you must change the .NET Framework version of the Application Pool used by the SSDM Scheduling Web Service to .NET 4.5.
The Migrator for Notes to Exchange applications and wizards need a directory that is accessible (read and write) to the admin accounts that will run the admin components and access source and target data and accounts, and that is shared (read only) to all users who will run the SSDM.
MNE selects the appropriate authentication mechanism automatically using information from the Exchange Autodiscover service. If MNE detects that Modern Authentication is enabled on the migration target, it uses Modern Authentication as the preferred mechanism. If Modern Authentication is not supported, MNE reverts to legacy mechanisms such as Windows Integrated or Basic authentication.
