I understand that support has been withdrawn for WebMail. I have migrated and tried to get WebMail up and running on WS2012R2 using instructions posted for 2008 and apparently some have got working on 2012 but with R2 I have had no joy. Attached a screen snip of the error.
If I can't get this to work I will use squirrelmail. Does anyone have the squirrelmail configuration settings to get it to work? Is there a document to assist with the settings?
Thanks.
