Hi, I have a really, really strange problem which my networking guys have been unable to resolve in the past 6 months.
In May we cutover to a new Exchange server on a network with a preexisting Cisco 7960 VoIP system. Since the day of the cutover, between 1 and 20 emails per day I send via Outlook/Exchange to internal network recipients are never received on the other end. I receive no System Administrator bounceback emails, but instead I get messages in my Cisco voicemail that say:
"A receipt, your message to one or more recipients, sent <datetime>, could not be delivered."
These are not from voicemails.
The problem seems - emphasize seems, not is -- worse when I have large attachments, but can occur with any email. Some days are worse than others; yesterday, I received 12 such receipts, but they day before, only 1. I can't correlate it to specific email individuals or mail groups on the receiving end. It doesn't matter if I'm archiving to a local PST file or not. It doesn't matter if my filing/filtering rules in Outlook are enabled or not. I have no Outlook plugins. I'm not out of memory.
All i know is that it looks like I'm not getting back to people, and this has been going on for ovr six months now. I am apparently the only person at this company (of 100+ employees) with this problem.
My buddy who runs the NOC at a major Fortune 10 financial institution says this can't be happening... but it is.
Help!!!!
