I got this strange issue reported a user unable to send mail to himself although he is able to send / receive emails to others with no issue . I tried sending a test mail to myself from affected user's mailbox (keeping user in CC) as expected i got the copy but user didn't. I analyzed header , there is no issue . Moreover there are no rules in place in user's outlook . We use exchange 2010 with OL 2007 in our environment . Pleas

Hello Aditya,

Following cmdlet can be helpful. substitute the user identity and see what result you get for NT AUTHORITY\SELF. It can be 'True' for Deny parameter. You need to set that to False to enable the user to send to himself/herself

get-mailbox "user identity"| Get-ADPermission | where {($_.ExtendedRights -like "*Send-As*") -and ($_.User -like "NT AUTHORITY\SELF")}

I checked its already set to false. Please suggest ?
