It appears that some people have not been receiving email sent to HSMS.Staff it turns out this is a Microsoft feature called ‘Clutter’. If you kept your inbox tidy and therefore regularly delete messages for the same source Microsoft decides that it must be clutter and automatically moves any future message from that source to the clutter folder it created.

Below you can find instructions on how to turn this automatic processing off.

 

Use Clutter to sort low priority messages in Outlook 2016 for Windows


In Outlook 2016 for Windows, "Clutter" can help you filter low-priority email, saving time for your most important messages. The email server keeps track of the email you read and the ones you don't. Once you turn it on, Clutter is automatic. As new email comes in, it takes messages you're most likely to ignore and puts them into the "Clutter" folder. The more you use it, the better it gets. And if you find Clutter isn't for you, you can turn it off.
