I have ZCO 5.0.19_GA_3082_5.0.3141.19, Windows 7 & Outlook 2007 w/SP2, server NE 5.0.19.
We tried following steps:
1. New installation of MS Outlook
2. New installation of ZCO
3. Succesfull config of account on Zimbra server
4. No problem with usual e-mails, sync is OK
5. I tried to sent e-mail with attached larger file (i.e. 3MB)
6. E-mail stays in Outbox with sending fails
7. Zimbra send/receive progress allways in this case displayed - Total 7.96 MB transferred
8. All sync from this moment are failed with report network connection failure
9. Data traffic on network is very high
10. This problem continue also after manual removing of e-mail from Outbox
We tried also this test on ZCO 5.0.22 with 5.0.22 NE server and ZCO 6.0.5 with 6.0.5 server. The problem was the same.
Does somebody have the same problem?
