OOF, Autodiscover and Outlook Certificate Issues
**This article will help to fix the below error for MS Exchange servers
I. Out Of office not working
II. Warning when opening outlook "server.domain.local"
III. Warning when opening outlook "autodiscover.domain.com"
IV. Make Internal URLs and External URLs the same.
**Most Exchange administrators don't check the complete URLs which Exchange uses for serving MAPI clients or miss URLs to set and add certificate names after installing Exchange server. Below are fixes for those errors.
1. First make sure you have a Forward lookup zone named "externaldomain.com" in your internal DNS server (to make your internal and external URL the same).
**2. **Then create the below A record in the newly created zone which points to exchange CAS/HUB server IP or load balancer IP if you have one.
a) autodiscover.domain.com
b) mail.domain.com (common name)
3. Then make sure you have all the required names added as SANs in your SSL Certificate. The names below are an example. i.e. the A records created in step 2
a) mail.domain.com (common name)
b) autodiscover.domain.com
4. Make sure IIS is enabled on the installed certificate.
Type "Get-ExchangeCertificate" in Exchange Management Shell and see IIS enabled or no.
