When installing a new Soft Token license, the following error is received:
"Defender Import Wizard
The allowed token count for the selected licenses are insufficient to cover the existing tokens. Licenses for an additional <xx> tokens are required"
Ensure that the license being imported is for the correct number of tokens. The license needs to cover all existing tokens.
Delete all non - required soft tokens then re-import the license. Unassigned soft tokens still consume a soft token license. These can safely be deleted..
Note, Soft token licenses are cumulative, for more information please refer to Knowledge Article 44179, Understanding the licensing process for Defender.
