Have a user that is experiencing the following in Outlook 2013 on a SBS 2011 system.
The message I received is as follows.
The message I was talking about that appears on my emails came back this morning. I opened my emails there were a few new items in there which I deleted, see screenshot 3 Then my inbox displayed screenshot 1 which revealed the extra message shown on screenshot 2.
it is not always a spam message that gets hidden.
Could it be related to the cached exchange mode. This is set at the default setting which is 12 months
