We have a single server Exchange 2010 deployment on Server 2008 R2 that works rather well. It houses about 200 mailboxes and is a single database. We're just struggling with one issue;
We're trying to figure out what is happening on the dot at 6:30 PM every evening for about 30 minutes. Performance starts to take a huge hit. Common tasks carried out in Outlook become a struggle for the handful of folks still in our office at the time. The only other proof I have is when I look at Virtual Machine from the storage side, the volume shows the I/O increasing from about 50-100 IOPS to 1200-1500. The busy disk falls directly in line with when the performance begins to tank.
Does anyone have any ideas on how I can figure out what it killing the performance at the same time every day.
I did check the Exchange Maintenance schedule but it was set for Midnight to 6AM (I believe that was the window of choice).
