Mail migration problem

I'm using your mail migration tool to move 11 Google Apps accounts to Zoho.

I believe it is all set up correctly.

The first account copied across 999 emails (according to your Migration information...I'm not 100% it's imported just 800-and-something, but that's the big issue).

It seems to have stalled at 999. There's been no change in over an hour. The other ten accounts all show as being "In progress", but also report that "No data found for this account".

Could you please let me know what's going on? Perhaps there's a limit on how many it moves an hour or something?

Thank you.
