Recently while helping on technet I identified this issue which is very rarely seen so I thought of sharing it here.

Issue:

All outbound email messages are getting stuck in the Drafts Folder.

Cause:

Permission change on the following GPO for the object – “Access this computer from the network”.

“Default domain policy”  –>Local Policies –> User Right Assigments

to only domainAdministrator user and domainDomain Users group on both GPO.

Resolution:

-Checked – no changes on the receive connectors

-Checked – Exchange verbs were normal as below:

250-EXCHANGE2K13.XXXXXXXXXXXXX Hello [x.x.x.x]
250-SIZE 37748736
250-PIPELINING
250-DSN
250-ENHANCEDSTATUSCODES
250-STARTTLS
250-X-ANONYMOUSTLS
250-AUTH NTLM
250-X-EXPS GSSAPI NTLM
250-8BITMIME
250-BINARYMIME
250-CHUNKING
250 XRDST

-Checked – Transport Agent

–Changed the Permission on the following GPO for the object – “Access this computer from the network”.

  “Default domain policy”  –>Local Policies –> User Right Assigments

• Administrators
• Backup Operators
• Power Users
• Users
• Everyone

“Default Domain Controller Policy”–>Local Policies –> User Right Assigments:

• Administrators
• Authenticated Users
• Everyone

-Then ran GPupdate /force on domain Controllers and Exchange servers

-Restarted Microsoft Exchange Transport Service.
