Exporting a List of Mailbox Names to a CSV File

EdbMails automatically loads mailboxes after a successful login to your source and target Exchange servers. However, due to Microsoft API limitations, it may not display more than 100 mailboxes. If you have more than 100, export the user mailboxes to a CSV file and load them manually.

Frequently Asked Questions

1. Why does EdbMails ask me to load Exchange mailboxes from a CSV file?

   EdbMails automatically lists mailboxes after you connect to the source and target Exchange servers. However, Microsoft API limitations can prevent EdbMails from displaying more than 100 mailboxes in the automatic list. If some mailboxes do not appear, export the Exchange mailbox list to a CSV file and load it into EdbMails.

2. How do I load an Exchange mailbox CSV file into EdbMails?

   In the EdbMails mailbox selection screen, click “Load Mailboxes using .CSV file”. Next, select “Load Mailboxes From Existing CSV”, browse to the CSV file saved on your computer, and select it. Click “OK” to load the mailbox list, then continue with the remaining migration steps.

3. Can I load more than 100 Exchange mailboxes into EdbMails?

   Yes. If the automatic mailbox list does not show all your Exchange mailboxes, you can use the CSV-loading option to load a larger list. This option helps EdbMails display mailboxes for selection; it does not change your license, the number of mailboxes you are licensed to migrate, or other migration requirements.

4. Do I need PowerShell to export Exchange mailboxes for EdbMails?

   No. You can export the mailbox list using Exchange Admin Center or Exchange Management Shell. After exporting the CSV file, load it into EdbMails using the “Load Mailboxes using .CSV file” option.

5. Where can I find the CSV file exported from Exchange Management Shell?

   If you use the Exchange Management Shell command shown on the EdbMails page, the file is saved as C:\Mailbox_Names.csv on the computer where you ran the command. If you use another export location, browse to that location when selecting the CSV file in EdbMails.

6. Does loading a CSV file start the Exchange mailbox migration?

   No. Loading the CSV file only makes the Exchange mailbox list available in EdbMails. It does not migrate emails, contacts, calendars, or other mailbox items. Once the mailboxes are listed, complete the remaining steps in EdbMails to begin migration.

7. What should I do if some Exchange mailboxes are missing in EdbMails?

   First, check whether the missing mailboxes are caused by the automatic listing limit, which may affect environments with more than 100 mailboxes. Export the mailbox list from Exchange and load the CSV file in EdbMails. If a mailbox is missing from the CSV file itself, check the exported list in Exchange before loading it again.

8. Can I load an existing Exchange mailbox CSV file into EdbMails?

   Yes. Select “Load Mailboxes From Existing CSV” in EdbMails and choose a CSV file exported from Exchange. The file should follow the mailbox-list format used in the EdbMails instructions, including the required mailbox details. An unrelated CSV file or a file with different columns may need to be corrected before it can be used.
