pst migration losing emails

pst migration losing emails

Hello,
Jaffrina from customer service was going to consult this problem with Zoho Mail developers. I post this here to see if others experienced same issue: Losing emails in pst migration process into Zoho.

Illustration:
Carrefour folder was moved into its own pst file and uploaded. Zoho lost 58 e-mails (1993 in outlook and migration tool log, to only 1963 in Zoho and later down to 1935.
  1. Originally 1993 emails
  2. Verified by migration tool log to be 1.993 emails too
  3. When reaching zoho, scrolling down the folder to the most bottom, I only found 1.963 emails
  4. Weirder, I tried switching to older zoho mail version, found only 1935 emails. Went back to newer zoho mail version, still finding only 1935 emails.

This happened to all 3 pst files I uploaded. A different pst lost 5 emails from 1390 to 1385. Another pst lost 31 emails from 1626 emails to only 1595 emails in Zoho.

Please help
