We use exchange 2007 and outlook 2010 and I have sent a mail to all staff mail group (300 Staffs).
None of the staff are receiving the email which I sent and I was supposed to receive a copy and i have not received this email as well.
I tried few things, when i send an email to myself i receive and also if i send to my colleague he receives. Only when i sent the email to this mail group the staffs are not receiving and also I am not receiving any NRD reports on my inbox and checked the junk mail as well.
When i open the sent folder i can see that the mail is listed on the sent item. Previously I used to send email to this group an it used to work successfully.
On the Exchange server C: Drive the free space is 3.95GB
D drive is where the Exchange database located, the free space is 70GB
There is another mail group(100 recipients) and if I send email to this mail group , it works.
Please suggest how to trouble shoot this.
Thanks in advance
