The Messages area is a great source of notifications and should be checked regularly as it may be requiring you to action errors.
Examples of Notifications you may see are :
as well as any errors or failures you need to action:
NB: Errors and Failures need addressing as the Letter print will continue to fail until you do so (the example above is advising you that the Referral ID mentioned is missing its NHS number - until the NHS number is added to that Referral ID you will not be able to produce the letter to print)
Finally can we ask that you regularly housekeep the Messages area - Mark messages as Read when you have done so, this will ensure your Messages are tidy and less daunting to look at.
