Exchange 2K3 sp2 on SBS 2K3 Standard Outlook 2K3 clients... All Microsoft updates on both sides This one girl at this client always seems to push her Outlook abilities and come up with oddball errors. She has a few distribution lists in her Contacts... One list is about 170 addresses...she added 4x new addresses last week. ...the following day..went to this contact list to open it.. and "'Cant open. Not enough memory available on the microsoft exchange server computer to perform the operation." Googling this is proving a bit fruitless....shows many people have bumped into this issue..but I cannot find an authoritative answer. It seems to open up fine if I go in through OWA Her mailbox has had the default limits as far as size removed. Network is 15x nodes. I'm guessing Exchange has some max size you can have for distro lists? If so, any way to tweak? Having a limit of under 200 seems....lame.
