Jared, While I might not have been following up thoroughly on the correspondences sent around by the group, I would recommend going to Internet Services Manager > Go to Default website (or whatever was created for the OWA) > Exchange > right click and click properties > Directory Security > Anonymous Access and Authentication Control and hit Edit button > Put Tick on Basic Authentication > Hit the edit button below and type your domain or type \. And click ok >then remove ticks on all the other fields. Click apply and then ok. It should not prompt you to enter your domain. Also for verification purposes is Exchange running behind a firewall? Such as ISA? With Kind Regards, Khan ____________________________ Faizal Khan MIS Manager Guyana Forestry Commission 1 Water Street, Kingston, Georgetown, GUYANA.
