Has any body experienced in exchange 2013 sp1 where a user goes to OWA and right clicks on deleted items and gets a 404 page cant be found error message. This previously was working within that last few weeks. besides windows updates and exchange security update KB3040856 I have not made any other configuration changes other then updating one of the exchange certificates. I initially had an issue with the certificate but found that I hadn't updated the backend cert in iis so once I did that the other issues I had went away. I have 4 servers, I have tried different users on different database's and have connected to each of my 4 exchange servers and still experience the 404 page. I have opened a case with MS but thought I would see if anyone else has seen this.

Hi,

I have seen the same issue before. I suggest to install the latest CU and check the issue.
