Adjustment in EWS after MS Exchange update (29.04.2025)

After the latest MS Exchange updates, the following error may occur in environments using EWS:

Error: The EWS Id is in EwsLegacyId format which is not supported by the Exchange version specified by your request. Please use the ConvertId method to convert from EwsLegacyId to EwsId format.

To resolve this, you need to get a new changeKey for the folders. The procedure is as follows.

  1. In the service console, run the command sys.ewsFoldersInfo()
  2. For each folder, new changeKey are visible in the result
  3. These new changeKeys need to be inserted into the EwsCreateProcessesFromMailCron.js configuration.
