OWA에서 Exchange IMAP Migration 마이그레이션 날짜 수정
Exchange IMAP Migration 마이그레이션이 OWA에서 잘못된 날짜를 표시하는 이유
Outlook on the Web (OWA) is the browser-based 이메일 클라이언트 for Exchange Online and on-premises Exchange Server. After an Exchange IMAP migration, OWA displays the 마이그레이션 날짜 for every email because it reads the same PR_MESSAGE_DELIVERY_TIME property that Outlook desktop uses. This property is set during the migration upload process and reflects the timestamp when Exchange processed the message, not when it was originally received.
OWA's date display is consistent with Outlook desktop: every email in 받은 편지함, 보낸 항목, and other folders shows the 마이그레이션 타임스탬프. Unlike some web-based 이메일 클라이언트s that reference the Date 헤더 for display (like Gmail web), OWA reads from Exchange's message store, where the delivery time is permanently set to the 마이그레이션 날짜.
For 조직s that primarily use OWA (common in environments where IT does not deploy Outlook desktop, or for 사용자 who prefer browser-based access), the impact is identical to the Outlook desktop experience. Every email appears to have been received on the same day. Users lose the ability to browse their 사서함 chronologically, search by date, or use OWA's built-in filtering to find messages from specific time periods.
OWA에 미치는 영향
OWA displays the 마이그레이션 날짜 in the message list for every email. The "Focused Inbox" and "Other" tabs both show messages with the wrong received date. OWA's search functionality, which supports date filters like "received:this week" or "received:last month," returns incorrect results because the indexed delivery time is the 마이그레이션 타임스탬프.
OWA's conversation view groups messages correctly by thread (using subject and message-ID), but the date shown next to each message in the conversation is the 마이그레이션 날짜. Users who hover over the date to see the full timestamp see the 마이그레이션 날짜 and time. OWA's "Filter" feature, which allows quick filtering by date range, becomes unreliable. For 사용자 who work exclusively in OWA, there is no alternative view or workaround that reveals the correct 원래 날짜s without inspecting each email's raw headers individually.
자주 묻는 질문
Is the date issue in OWA the same as in Outlook desktop?
예. Both OWA and Outlook desktop read the same delivery time property from Exchange. The 날짜 손상 caused by Exchange IMAP Migration affects both clients identically. Fixing the dates on the server corrects the display in both OWA and Outlook desktop simultaneously.
Can I see the 원래 날짜 in OWA by viewing message headers?
예. In OWA, you can view the original Date 헤더 by opening a message, clicking the three-dot menu, and selecting "View message source." The original Date 헤더 shows the 올바른 날짜. 그러나, this is a manual process impractical for thousands of emails.
Does Redate.io fix dates for both OWA and Outlook at the same time?
예. Redate.io corrects the email at the Exchange 서버 수준. Once the Received 헤더s and delivery time are fixed, the 올바른 날짜 appears in OWA, Outlook desktop, Outlook mobile, and any other client connected to 사서함.
