A user has migrated from a native mail server (hermes) to Exchange online. AS Hermes mailbox had a limited space, he saved his conversations in local folders. I'm now trying to move those conversations from local folders into the new Exchange online mailbox set up in Thunderbird. But not all the conversations are copying. The original shows 1,277 conversations. I have tried to copy to and move to and only 377 conversations are listed. Can you advise please?

thanks

Thank you for your post. With more tinkering I have found the following solution.

  • Download and install the Addo on ImportExport Tool in Thunderbird
  • Select all the emails I want to copy in the local folder and select Save as Eml message
  • Store somewhere suitable
  • Create a new folder in Exchange
  • Right click and Import messages

Leave for an hour whilst it copies

Hi Copy, and Paste is more reliable than drag and drop. Definitely copy, not move. I suggest copy them in smaller batches, the Exchange server may have a limit on how many emails can be processed in a given time frame. Work up from maybe 500 emails at a time (and if you are working in conversations go lower as there may be many emails in one conversation). It is a lot for the server to process large batches all at once, takes times, so let it rest a bit between batches to be sure it has all transferred and finished indexing at both ends.
