Have you tried adding the -BadItemLimit 1000000?

Thanks Will for your prompt response.

Tried to put '-BadItemLimit 1000000 -AcceptLargeDataLoss' but it's giving me the below;

WARNING: When an item can't be read from the source location or can't be written to the target location, it will be
considered corrupted. By specifying a non-zero BadItemLimit, you're requesting that Exchange not copy such items to the
 target location. When the request is complete, such corrupted items won't be available at the target. When the source
is deleted, these items will be completely lost.
New-MailboxRestoreRequest : Source mailbox's legacyExchangeDN '/O=....../OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/
CN=......' doesn't match the legacyExchangeDN or X500 proxy for target mailbox '.......'. Use the 'AllowLegacyDNMismatch
' switch if you want to allow this operation.
