I have a problem with my outlook 2010 install, has been working fine for a long time, but within the last month i can no longer send emails with attachments. everything else works normally. the attachments can be as small as 60kb and they will not send, just comes back with an unknown error.
I just installed thunder bird on a different PC, and could successfully send emails with attachments with the same account settings
Looks like a common issue as a lot of people report this same error. I don't want to lose all my emails and contacts, is there a way I can delete my account and/or database and create a new one without losing everything as I think that's what the issue may be? My mail database is only 150mb.
