Error: "The task activity item was unable to execute due to a problem with the task credentials. (91561)

After opening the properties dialog for a task that uses alternate Task credentials (credentials other than the default service account), the task fails to run with the following error:

"The task activity item was unable to execute due to a problem with the task credentials. The user that was used to execute the task activity item is <domain\username>"

When using alternate Task credentials, if the password for the account is not re-entered each time the task properties dialog box is opened, the password is defaulted and an incorrect password is saved

WORKAROUND:

Each time the properties dialog box is opened for a task that uses alternate Task credentials, re-enter the password for the account prior to closing the Task Properties

STATUS:

Defect ID TF00202680 has been raised for this to be fixed in a future release of MessageStats
