    Hi Barry,

    You can refer this link to know more about the migration of public folders from Exchange to Office 365.
    The reference link of Microsoft support team is as follows:

    https://technet.microsoft.com/en-us/library/dn874017(v=exchg.150).aspx

    I hope this is what you are looking for.

    Best,
    Michael

    Thanks for your reply Michael.

    I have already gone through all the steps in the link that you mentioned.

    All mailboxes are successfully synced. But only 2 mailboxes are not syncing.

    I didn’t get any error for 3 days & then all of a sudden I get “SyncTimeoutException” this error message without any description about this error.

    This is my issue. What should be done now?

    Thanks,
    Barry

    Public Folder migration to Office 365 can be full of hassles at times.
    Even I got several errors while performing this migration.

    Do those mailboxes keep syncing until they timeout?

    You can try to delete migration batch. To be more precise, delete the failing public folder mailboxes and then restart the migration process.
    I guess you have created more than enough mailboxes, based on PF size?

    Please revert back.

    Yes, Michael the mailboxes stay in syncing mode until they timeout!

    I have got about 232 GB size of public folders, the script provided in the link of the Microsoft created those mailboxes.

    So what do you suggest? Should I delete the migration batch from Office 365 admin center or should I only delete the two error mailboxes? and create new migration batch using PowerShell?

    Ok Barry. So you should remove the migration batch (except the endpoint). Also, remove the two failing mailboxes and recreate them through PowerShell. At last create a new migration batch. 🙂

    Ok thanks, Michael. I will perform these steps now.

    But I wanted to know that can I recreate those 2 mailboxes via EAC??

    I can remove these mailboxes using PowerShell but the recreation of these mailboxes is a lengthy process for me.

    Yes sure, Barry. You can do this using EAC as well 🙂
    Please let us know if you still face any issue regarding this issue.

    Also to avoid such issues in future, you can use a third-party tool to perform Exchange to Office 365 migration.
    One such tool is provided by SysTools Inc. Please refer the link of their product:
