You are 60% through an IMAP migration. The progress bar stops moving, the log fills with timeout errors, and the project deadline hasn’t changed.
A stalled IMAP migration is rarely random. Almost every stall traces back to one of three causes: server throttling, broken folder mapping, or delta sync (incremental sync) failures. This guide explains each one, how to spot it, and how to recover without redoing the work you’ve already finished.<\/p>\n<\/div>\n
