  • 1. Time stamped in SMTP log incorrect
    The time stamped in the SMTP log is 5 hours off. Other Windows log files are ok. Messages are stamped with the correct time. It seems to only be the SMTP log. Any ideas?
  • 2. Exchange 5.5 and relaying
    I have an exchange 5.5 sp4 server that appears to be relaying mail. I've looked up information on preventing Exchange 5.5 from being an open relay and configured it accordingly. I've tested it with abuse.net manually through telent and it says it's not an open relay, but when I look at the outgoing mail queue in the IMS there is a bunch of mail in there that is definitely not business related. The ones that are still in the queue are there because of being host unreachable. I don't know how many are acutally going through. Does anybody have any suggestions?
  • 3. Master Category List
    I there a way I can have everyone Outlook pull the Master Category list from the Exchange server or is this something that must be maintained at each workstation?
  • 4. invisible Attachments
    Hi NG, how do I solve, that programtically inserted Attachments are invisble in Outlook 2003 clients? The Mail contains the attachment (you can even save the attachment with a third party tool). But there is no attachment visible if you check the mail with Outlook 2003. Any ideas? Greetings Lennart
  • 5. OWA new messages created with a "?" as the first character
    Each time one of my users creates a new email or replies to an email through OWA the first character is a "?". She cannot see the ? until after the email is sent. Could this be OWA trying to use stationary or a signature or header?

Outlook 2003 via POP3 to Exchange = BANDWIDTH HOG!

Postby tdavis34 » Tue, 08 May 2007 08:44:19 GMT

Hi all,

I'm not sure of the right way to phrase this, but we have our
bandwidth-metered Exchange server in a colocated environment. I use
Outlook 2003 to check mail from this machine using POP3, because I
don't want to go the MAPI route. I pretty much have my computer on all
the time, and Outlook is always open.

I discovered today that Outlook is consistently eating up an average
of 3 KB per SECOND in conversations with the Exchange Server over
POP3. Now, I have it set to check for messages every 1 minute, which I
know is a lot, but honestly, I never dreamed it would eat up so much
bandwidth.

The question, of course, is what is going on between Outlook and
Exchange that requires so many bytes? The one thing I can think of is
that I leave all of my messages on the server so I can use the web
client when I'm traveling, and I'm up to around 3000 now, but I never
expected that this would somehow affect ongoing bandwidth.

Any ideas? Is Outlook possibly telling Exchange about the messages
I've already retrieved with every single request?

Thanks,

Tim

Well done for discovering one of the drawbacks of POP3 and now pulling
the email off the system.
I would really switch to RPC over HTTPS. Anyone will tell you the same
and it's good advice.

Mark,

Thanks so much for your reply. I did not know about this option; I've
since done a little research and it seems perfect. Very much
appreciated!!!

1.Can POP3 to Exchange via OE5, but cannot POP3 to Exchange via

Correct-

Exchange Server 2003.  Again, the weird part is any new AD users created, 
and mail enabling them, can POP no problem with OE6.  I was thinking and the 
only difference is the existing users were created (mailboxes too) when I did 
not have the POP3 service running.  Last week I started the process and any 
new users can POP, but old (exisiting users cannot).

Thanks for your help-

2.Can POP3 to Exchange via OE5, but cannot POP3 to Exchange via OE6

Existing users can pop to exchange through outlook express 5 but cannot pop 
to exchange through outlook express 6.

Also, new (AD and Mailbox) users created today can access pop through from 
both outlook express 5 and 6.

The new users Exchange Alias are set to the AD logon name.  The existing 
users Exchange Alias are set to the email address name, however when changed 
to AD logon name they still cannot connect in OE6.

For instance New User ( Joe Black) 
Email Address = joe@"company".com
AD logon name = jblack
Exchange Alias = jblack

Existing User ( Mary Black)
Email Address = mary@"company".com
AD logon name = mblack
Exchange Alias = mary

Logon using Secure Password Authentication is checked on OE client for all 
users.

On OE6 I receive Logon banner at connection requesting Username, Password, 
and Domain

Any Help would be great!

Thank you-

4.Outbound Mail hogging bandwidth

Hello,

I was wondering if anyone can help with an issue thats been bugging the hell 
out of me for ages.

I'm running Exch 2003 on SBS2003 (obviously). Everythings up to date and the 
general day to day performance is fine.

However, when I, or any of the other users, send mail to 10 or more people 
outside our organisation, the internet traffic is brought to a crawl until 
all of the mails have been delivered. It seems like the exchange server 
keepts trying to contact a server if it fails to contact it on the first go.

Is there any way to increase the length  between retries??? Or if anyone has 
a better reason as to why the performance drops, i'll be happy to hear it.

Help :-)


Cheers

Dave

P.S. I had the same problem on Exch 2000
