Outlook 02/03 452 Too many recipients…

Locked

I am supporting a Windows 2000 network (27 clients) with POP3 email outsourced. Workstations are all XP ProSP2 fully patched running Office 2002 and 2003 also fully patched. Several users have recently (in the past 2 months) been getting the following Undeliverable message when sending to the entire office (27 email users):

The following recipient(s) could not be reached: Name, Date & Time, 452 4.5.3 Too many recipients.

Has Microsoft implemented some kind of BLOCK through one of the Office Service packs or patches recently because of SPAM and DOS problems?

We have NEVER had any problem with distribution size in Outlook and I can find NO reference to any “new” restriction to distribution list size.

I have talked with our POP provider and they have no restrictions.

Thank you, NavTec

Are you sending out through your ISP or your POP provider?
Some ISPs will not allow for mail to be sent through any mail servers other than your own or theirs.
If you are then take it up with the ISP. If it is happening on all clients then it must be a due to a limit on the SMTP server.

G Partridge,

Thanks, I needed that little (intuitively obvious) brain jolt.
And once again I will never understand SBC. When our T1 line went in 3 years ago they assigned us mailhost.chi.ameritech.net for our smtp services. Here is their response to my email an hour ago:

mailhost.chi.ameritech.net has a 25 recipient limit per mail item. This is actually classified as a residential class mailer and will have stronger restrictions.

bizmail.sbcglobal.net is a Business Class mailer and has no recipient limit as well as some controls that are designed for business users.

Thanks again, we’re up and running… T. Ward / NavTec
