Zoho MailでのZoho Migration Wizard移行日付の修正

Zoho Migration Wizard moves emails from external platforms into Zoho Mail by downloading each message and re-uploading it to Zoho's servers. During this process, Zoho Mail records the upload timestamp as the message's INTERNALDATE and delivery date. The Zoho Mail Webインターフェース uses this delivery date for its display, meaning the 移行日 appears next to every email in 受信トレイ and other folders.

Unlike Gmail (where the Webインターフェース may show the Dateヘッダー and partially mask the issue), Zoho Mail's Webインターフェース displays the delivery date from its message store. This means ユーザー see the 間違った日付 whether they access Zoho Mail through the web browser, Zoho Mail mobile apps, or third-party IMAP clients. There is no client or access method that avoids the in正しい日付 display.

The problem is 特に disruptive for ユーザー migrating from platforms where their email history spanned many years. A メールボックス with a decade of correspondence suddenly appears as if every email was sent and received on a single day. Zoho Mail's search, sort, and filter features all operate on the corrupted date, making it impossible to navigate メールボックス chronologically without a fix.

Zoho Mail's Webインターフェース, desktop app, and mobile apps all display the 移行日. The inbox view, sent mail view, and folder views show the same in正しい日付 for every email. Zoho Mail's search bar supports date-based queries, but these return incorrect results because the indexed date is the 移行タイムスタンプ.

Zoho Mail's Streams feature (which provides a social-media-like view of email threads) also uses the corrupted delivery date, showing incorrect chronology for conversations. Zoho Mail's email forwarding rules and filters that use date conditions operate on the 間違った日付s. Organizations using Zoho's integrated suite (Zoho CRM, Zoho Projects) that pull email data may display incorrect email dates in linked records, affecting workflows that depend on accurate email timelines.
