We have a client who is having an issue with their autodiscover. They have an Exchange Server 2013 with CU1. After attempting to run an update on the server (Win 2k8R2) I needed to revert the changes, so I fell back to the snapshot I took before I began the maintenance.

After I rolled back to the previous snapshot, Exchange's autodiscover is no longer publishing the EXPR section of the Autodiscover.xml file. We can see the EXPR when we run "Get-OutlookProvider".

Here is the output of the autodiscover on a client computer:

    <?xml version="1.0" encoding="utf-8"?>

We have tried running "Remove-OutlookProvider EXCH" and then adding it back by running "New-OutlookProvider EXCH", but it still doesn't work.

As you stated that the EXPR is missing, then the commands you need to run should be:

Remove-OutlookProvider EXPR
New-OutlookProvider EXPR
