Hi, I've gone live with Exchange 2007 in our environment, but have 2 remaining errors in the Event Viewer. Can anyone help? Error 1: Microsoft Exchange OLEDB was unable to do Schema propagation on MDB startup HRESULT = 0x80040e19 Error 2: Error updating public folder with free/busy information on virtual machine MYSERVER. The error number is 0x80004005. This is the only exchange server in the Org. No exchange 2003 servers.

Fixed both errors. Used powershell Set-PublicFolder -identity "\NON_IPM_SUBTREE\schema-root" -name "schema" to rename the folder. Restarted Information Store and all is well.

Tell a lie. Doing this fixed the first error but has not fixed the second one so I'm still stumped.

Now fixed the second error. Had to contact Microsoft, but they sorted it for me. The problem was a redundant free/busy folder left over from the old Exchange 2003 Server. You could see that by running get-publicfolder -identity \NON_IPM_SUBTREE -Recurse that it mentions First Administrative Group as a Free/Busy folder. It had no replicas so we added one using [PS] C:\>set-publicfolder -identity \NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=2007/ou=First Administrative Group -replicas "public folder database" Lo and behold, the error has gone. Thanks Microsoft!!

This looks like an error I am getting as well. Everything else I can identify and verify except the /o=2007, what is this value?

o is the Exchange Organization Name. e.g. My Software Company Limited

Thats what I thought,the example only had "2007" was throwing me for a loop.
