Hi,
We have been using Dovecot 1.0 to serve Maildir format over IMAPs to a client with an office of around 30 people, and a remote office of 10, all using Outlook 2003. While users in the base office (location of server) are not having issues with the server users in the remote office are often having problems with Outlook freezing, or not being able to connect. The dovecot log shows them logging in, but users report not being able to open any mail.
We are having similar problems with 2 users that are often on 3G cards, in that the headers download but when they try to open the file it gives the 'must be online to download the message' error, even though they are still connected to their 3G.
The net connection for the server is 2mb sdsl, which I have tested myself (using thunderbird on linux!) and achieved good throughput and reliable mailbox navigation.
Is there any Outlook work arounds we could be using? (currently using idle timeout work around)
Any help is very much appreciated.
Thanks, Mark
