Hello Stef,
I am very sorry for the late reply,

No errors in log

Renaming folder olsow is not working, no message but it is not changing

My own Email folders are now problem, problem only exist with shared mailbox
In outlook there is now problem

We are testing EmClient and having  the same problem!

We use exchange 2007

I also discovered that shared folders  are not updated when automatic updating  the folders
It only works when changing to another folder and back
