OWA redirect URL error or stating you should use HTTPS when no certs are used

We’ve had an issue where we log on to the OWA URL and the site either gives us a redirect URL error or ask us to use https:// instead of  http:// when we are not using SSL/certs

Eventually we logged into powershell and recreated all the OWA virtual directories. This solved the issue and we could access OWA again.

Unable to open items in mailbox

We had an issue where we were unable to open any new or old mail in any user’s mailbox.

We then found that the antivirus software was reloaded on the Exchange servers and no exclusions where set. After stopping the antivirus software’s services we were able to open any mail as per usual.

The exclusions where setup and services started.

Exclusion list for Exchange 2003:

MSDTC cluster resource duplication error

I had an issue where a change caused my Exchange cluster to loose all it’s SAN connected disks and it kept failing over.

When opening Cluster Administrator I received an error stating a duplicate MSDTC resource can’t run and within the cluster admin the MSDTC resource did not want to start.

I then took all resources offline andshut down all the cluster nodes.
Started up Node 1, then Node 2 and lastly node 3. I started all resources on the first node including the MSDTC resource. Then started resources on Node2 and all was fine again
