Hi! I've just migrated (two weeks ago) an EX2010 to EX2013. All seems to work perfectly (after a lot of hard work), but there is something really strange.Every day, at 13.00 something is happening on the server that runs for almost and hour and locks the owa access saying that annoying message with the sad face...
I've checked the maintenance hours on ecp and are configured to run at night.
Also checked the automated tasks on the server and it seems that nothing is running...
Some ideas? Help please! users are about to hang me!
