Outlook에서 수동 IMAP 복사 날짜 수정
수동 IMAP 복사가 Outlook에서 잘못된 날짜를 표시하는 이유
Many 사용자 and 관리자 attempt to migrate emails between 메일 서버s by adding both IMAP accounts to Outlook and dragging or copying messages from one account to the other. This manual approach uses Outlook as an intermediary: Outlook downloads the email from the source IMAP server, then uploads it to the destination IMAP server using the IMAP APPEND command. During this upload, 대상 서버 adds a new Received 헤더 with the current timestamp.
The manual IMAP copy approach has no mechanism for preserving the original INTERNALDATE. Unlike dedicated migration tools (which at least attempt to set the INTERNALDATE during APPEND), Outlook's copy operation does not pass a date parameter to 대상 서버. The destination server sets the INTERNALDATE to the upload time, and adds its own Received 헤더. Both date sources now reflect the copy date rather than the original received date.
Users who perform manual IMAP copies often do so because they believe it is the simplest approach, or because they are moving a small number of emails. 그러나, even a small manual copy can corrupt dates for hundreds of messages if an entire folder is selected. The 날짜 손상 is not apparent until after the copy is complete, when the 사용자 notices that all copied messages now show the copy date in Outlook's received column.
Outlook에 미치는 영향
After a manual IMAP copy, Outlook displays the copy date for all transferred messages. The "Received" column shows when the message was copied, not when it was originally received. If the 사용자 deleted the originals from 소스 서버, there is no way to see the 올바른 날짜s in Outlook without fixing the headers.
The impact is identical to a migration tool-caused 날짜 손상: sorting, searching, and filtering by date all operate on the copy timestamp. Outlook's date-based groupings (Today, Yesterday, This Week, etc.) are disrupted. Unlike migration tool scenarios that 일반적으로 affect an entire 사서함, manual IMAP copy 날짜 손상 may affect a subset of 사서함 (only the folders or messages that were manually copied), creating an inconsistent mix of correctly-dated and incorrectly-dated messages within the same 사서함.
자주 묻는 질문
I only copied a few folders manually. Can Redate.io fix just those?
예. Redate.io scans the entire 사서함 and identifies only the emails with corrupted dates (where the INTERNALDATE does not match the original Date 헤더). It fixes only the affected messages, leaving correctly-dated emails untouched.
Is manual IMAP copy worse than using a migration tool?
In terms of 날짜 손상, the result is the same: 대상 서버 stamps messages with the upload date. Manual IMAP copy through Outlook is actually worse in one respect: it does not attempt to set the INTERNALDATE, whereas some migration tools at least try to preserve it.
Can I prevent 날짜 손상 when copying emails between IMAP accounts in Outlook?
Outlook does not support setting INTERNALDATE during IMAP APPEND. There is no way to prevent 날짜 손상 when using Outlook to copy between IMAP accounts. If dates were corrupted, Redate.io can fix them after the fact.
