Embodiments of the present application provide a mail migration method and device,
electronic equipment and storage medium, the method comprising: a
server of a first mail application receiving a to-be-migrated mail
list sent by at least one target
client, wherein each target
client is a
client that logs in a
server of a second mail application using account information of a same target mailbox account, determining a target mail
list according to a time stamp of each to-be-migrated mail
list, determining a migration task of each target client according to a mail identifier to be migrated in the target mail list, and distributing each migration task to a corresponding target client, so that each target client acquires mail data of a corresponding target mail from the
server of the second mail application according to a target mail identifier in the received migration task, and sends the mail data to the server of the first mail application for storage. Based on the method, mail migration can be synchronized by multiple clients, improving the mail migration efficiency.
