How to Migrate Thunderbird to Exchange Server Manually?
Method-1: Using IMAP Sync (Best for Small-to-Medium Mailboxes)
In case the Exchange Server you are utilizing supports IMAP, or if your Exchange/Graph account is being used in Thunderbird, both accounts can be synchronized at the same time.
- Setup Exchange in Thunderbird: You have to set up an Exchange account in Thunderbird. To do this, you can make use of native support or IMAP/SMTP configuration settings that are provided by the IT administrator.
- Open Both Accounts: You will have to start Thunderbird and look for both old local/IMAP folders and new Exchange folder in the left sidebar.
- Use Drag and Drop Feature: You can select emails or complete folders from the old Thunderbird profile and drag and drop them into Exchange folders.
- Wait for Synchronization Process to Finish: You will need to let Thunderbird carry on the synchronization process until the emails are uploaded back on the live Exchange Server.
Please Note: In order to migrate Contacts & Calendars from Thunderbird to Exchange Server, they will have to be first exported into .csv and .ics formats respectively using the Tools >Export option and then imported to your Exchange Server destination individually.
Method-2: Manual Export via EML & Outlook
You may export your local files to your Exchange-connected Microsoft Outlook through the ImportExportTools NG add-on.
- Install the Add-on in Thunderbird:
– Open Thunderbird and move to Tools > Add-ons and Themes.
– Look for ImportExportTools NG, get it installed, and restart Thunderbird when you finish.
- Export Emails in EML Format:
– Right-click on the desired folder in Thunderbird, for example, Inbox.
– Select ImportExportTools NG from the list and then click on Export all messages in the folder option and choose the EML format to save messages on your local drive.
- Importing into Exchange with Outlook:
– Log in to Microsoft Outlook using your Exchange account.
– Go to the folder where you want to import your messages to (in Outlook or File Explorer).
– Drag and drop the previously saved .eml emails into your Exchange folder in Outlook (however this might take some time as you may have hundreds or thousands of messages).
Limitations of Manual Approach
- Susceptible to failures in connection, collapse, and potential loss of data while carrying out bulk data transfers.
- Extremely slow speeds and bottleneck issues in the process of uploading and transferring thousands of emails.
- Forces email programs like Thunderbird to jam, freeze or fail completely.
- Does not retain current sub-folder structure, requiring recreating of the folder structure manually.
- Experiences tough server rate limitation and restrictions in transferring files from Exchange.
- Requires third-party add-ons that need to be set up and configured separately.
- Endangers the integrity of metadata making the actual delivered date changed and read/unread status lost.
- Results in having huge files drop off, not linking properly and being completely removed.
- Imposes cumbersome multi-action manual process of exporting, saving, finding, and uploading files.
