I am having an issue where a user is not receiving some emails that are sent through to him.
I believe they are from certain senders and not just random.
We had an issue recently where I had to delete the X400 address and let it recreate. this seemed to solve my problem. Emails started going through to the user.
Although I recently have been told that there are a lot of emails not making it through to him.
I have had an issue in the past where an account has been recreated and users who are sending to him have had his old address info saved in their outlook which causes emails to look for old info and not get through, this was solved by getting senders to delete their saved addresses from outlook.
Has anyone seen anything like this? and if this is the issue is there a better way of solving it than getting all senders to delete their saved address from outlook?
Any help would be great, This problem has really stumped me.
