OWA error Rights management operation failedOuch! What to do?
Open exchange powershell
First step is to figure out that IRM is enabled in your exchange 2010
1. Log on to the exchange server and open (as Administrator) the Exchange Management Shell (EMS)
2. Run "Get-OWAVirtualDirectory | FL" and search for IRM; you'll probably see that it's enabled.
3. Run "Set-OWAVirtualDirectory -IRMEnabled $false"
or you could provide the name of the identity using the -Identity "<identity goes here>"
[PS] C:\Windows\system32>Set-OWAVirtualDirectory -IRMEnabled $false -Identity "EX2010\owa (Default Web Site)"
4. visit owa (Default Web Site) in your IE
Now reset IIS and try OWA again.
