Exchange 2010 - User can send and receive emails from internal users and can send to external but can't recieve from external users

Hope Someone can help me.

Recently users mailbox was full & we made changes on the exchange, gave him more space. Also user cleaned his mailbox. after doing that user still unable to receive mail from outside emails. I can see the emails hitting our spam filter and no error message on other end as well. user exist in the spam filter as well. btw we are using barracuda.

Any help will be much appreciated.

Anything in your Submission Queue?

Did the user actually clean his mailbox (or just throw everything into the Deleted Items folder and leave it there)?  What is the size of the mailbox vs Mailbox restrictions?  How does the size of his mailbox compare to the restrictions?

I'd run the Powershell

Get-MailboxStatistics to check the size of the mailbox

Please try to connect directly to the exchange server using a browser instead of a client.

Using OWA try to see if the users has all missing emails, if this is correct I will remove the users settings on the client computer and recreate the profile.  If emails still don't flow as expected check user mailbox for Send/Receive limits and increase them to match user's needs.

As mentioned earlier, there are several things to consider when trying to reduce a mailbox size, like retention times for deleted messages and backup frequency.
