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
