The last few days our Inbox has been receiving emails that we had previously set rules to place into our Junk box.  When we try to set a new rule using the sweep function (as we have in the past) the message stays in the InBox and we get the following message:

Sorry, Outlook wasn't able to complete this request. If you keep seeing this message, go to Service status to check if there's a problem with Outlook.           

We have looked in the Service status and it states that everything is running normally. 

This is getting very frustrating.
