Thank you all,
idp_qbn: I think that *.pst files are not good idea because its large, and because of size vulnerable for corruption. but thank you for advise. It was my first idea.
Stefano: As far i see you are one of the masters of SME. I understand technical advantages Thunderbird against MS outlook but it is only my point of view. Layers (i mean Lawyers
) are used to use Outlook because of their's habits and exchange meeting appointments with calendar, syncing calendar with mobile devices and ..... - they want to have outlook.
Mary: I would like to assure you that i know how to use search on forum and i wrote in my first post that i was thinking about MailArcihiva but this is not exactly solution i was thinking. there is a chance that I didn't understand idea of MailArchiva. in that case please correct me please and if you have any expiriences please share with us (share with me)
I saw how Symantec Vault is working and it is fantastic solution (except price) all email are tagged and searchable (attachments also) directly from MS-Outlook, but e-mails are archived elsewhere. when user click on e-mail (in fact link of email) which was looking for server is unpacking it and push full message directly into Inbox. in that case mail box with 30 gigs of e-mail is using 500-600 MB ost (ost is pst file but for MS-Exchange accounts) file locally . I was just wondering is there somewhere similar solution for opensource platforms. Maybe with kind of email client plugins or so.
BTW i know that bigger hard drive is cheap solution but performance for searching email is kind of nightmare
On the other hand i can understand my Layers-Lawyers that they need access to previous emails from past years because court cases in Poland can take 3 to 5 years if case is simple
Thank you once again and waitng for more
