Recently I had an issue with OWA and ECP on Exchange 2010. After unsuccessful RU Update both are displaying following :
It is unable to remove the OWA Virtual Directory from EMS in order to recreate it.
Error was something about”Metabase properties” “metabaseeigenschaften”
Downloaded Metabase Explorer and removed the OWA VD information form IIS.
Expand “LM” –> “W3SVC”–>”1″–>”Root”–>”OWA” Delete OWA
IIS reset. Then deleted the owa VD from ADSI edit. Under Configuration name context Servers–> Protocols->HTTP–>OWA VD
I am still not able to create new OWA VD:
Error in EMS – web object “Exchange” already exists
I hat to delete also “Exchange, “exchweb”” and “Public” from IIS .
After that the new-OWAvirtualdirectory when without errors. OWA and ecp are accessable. Authentication needs to be corrected after that and Internal and external urls.
