Status: RESOLVED DUPLICATE of bug 534835

(Thunderbird :: Folder and Message Lists, defect)

Description

[cove_s]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.15) Gecko/2009101601 Firefox/3.0.15 (.NET CLR 3.5.30729)
Build Identifier: Thunderbird 3.0 RC 3

Continuously re-downloads the same messages via IMAP from Microsoft Exchange via IMAP rather than only downloading updates to the IMAP folders. 

Environment observed with:
Server: Microsoft Exchange (via IMAP) 2003, 2007 and 14
Client OSs: Window Vista 64bit, CentOS 5.3 64bit
Thunderbird versions: 3.0 (under CentOS 5.3), 3.0 RC3 (under Windows Vista 64bit)


Reproducible: Always

Steps to Reproduce:
1.Setup IMAP account on Microsoft Exchange 2003, 2007 or 14.
2.Populate inbox w/ 6300 messages (6300=current case, may not be relevant though)
3.Configure Thunderbird to connect to download messages, including the full body for indexing.
Actual Results:  
Thunderbird downloads the messages in the inbox, and other folders, repeatedly. At some point it does appear to stop for a while, though reports are vague; from 2hrs to 1 day, the repeated downloading eventually stops.

Expected Results:  
Messages are downloaded once, and only updates to inbox (or other folders) are downloaded.
