I have the above installed on Vista Ultimate. Some emails do not leave the outbox for reasons that I cannot discover. I receive no error massages. Once these offending emails are in the Outbox they cannot be deleted and the message "The folder is Full" is received when a delete is attempted. I cannot discover which folder it means and suspect that this is a red herring anyway. In desperation I have removed Norton from my machine and now only have Windows standard protection items installed. The problem still exists. Other emails sent later mostly get sent even though a number of other emails permanently sit in the Outbox. If anyone can help with this it would be greatly appreciated. I have searched the web and found no other issues with these characteristics. Many thanks. Lawrence Moss

I know you said you've got Outlook 2007, but is the PST file by chance migrated from earlier versions of Outlook? Outlook 2002 and below have a 2GB pst limit, and this could cause the issue. If you did in fact migrate, i'd import everything into an outlook 2007 pst, even if you aren't at your 2GB limit. as described here: http://support.microsoft.com/kb/304863

I'm having the same issue, and at the same time, Outlook has stopped indexing. I tried rebuilding the index, but wound up with no index at all, so I can't search old emails - a HUGE problem that is costing me big time in productivity. I've seen online that we might need to run scanpst.exe, but when I try to do that, I can't locate the outlook pst to scan. Maybe all of this will help someone figure out an answer for both of us! Thanks - Jennifer

Yes I had migrated as you suggest. My file size was about 400MB as I archive and compact quite regularly. I have now converted to the 2007 format and I am at a loss to know why the migration process does nothandle this automatically or at least issue a warning. I read elsewhere that the problem of mail being stuck in the outbox and causing a sort of spasm in Outlook is caused by an anti virus programme conflict. Could be between two AV progs. or between a single AV prog and Outlook 2007. I use AVG free version and have played with the settings to some effect and only time will tell whether this has worked. I have tried paid for versions of Norton (which seems like a virus in itself) and Zone Alarm. I have given up on the latter due to poor support.

you don't want to ever have 2 antivirus scanners on a single computer there is no intuitive message or warning regarding the 2gb limit. you need to export items from the old into a new if this is the case. http://support.microsoft.com/kb/830336

I had the same problem, By the wayI also have vista ultimate installed, office 2007, andI have installed all the updatesI could find for my New PC, which has; intel quad core, 2gb ram, nvidia fx quatro 3500 card. Here's what I found, and a work around. if you select an email address that you found in the contacts database, the email will not be sent it will stay in your outbox, and make outlook crazy, meanig it will try forever to send that email in an endless loop if you type the actual email adress into the to: field, it works with no problem! sounds stupid, and it is, basically outlook has an issue resolving peoples names and emails that you select from their internal contact database there maybe another update out there to fix this, in the mean time, just type the actual email address of the person, you are trying to send the email to this works, outlook sends it , no problem RR

i guess i lost my post, here it is again what i found is that if you use an email address that you select from the outlook contact database the email will not be sent, outlook goes into an endless loop if you just type the actual email address in the to field the email is sent out no problem i hope this helps RR

Sounds like my problem to a tea ... anyone making any headway on this problem?My post in another forum:<quote>I have a single client running Outlook 2007 (but this also happened with 2003) connecting to Exchange 2003 in SBS 2003 in a domain environment. Certain emails with no particular pattern (that I have discovered) get stuck in the outbox and attempt a send repeatedly. The only way I could tinker with this behavior was to go into the 'To' box, clear it out, and manually type the email addresses in. For one particular message, the 'stuck' format was:John Doe (john@doe.com)and I just changed it to:John Doe [john@doe.com]and it sent successfully.The main problem here is that the emails that stick are repeatedly firing at the Exchange box causing the priv1.mdb to grow by gigs a day. Any idea what is going on here? Another symptom I forgot to mention is that often the emails will have 'None' for a date.</quote>J. Clark - Viesoft
