Jack, Liza said, our email service is very slow and people missing a lot of important emails. We are not able to figure out the actual issue. Can you please help us?

He checked and figure out that the email service (Rediffmail) they used could not meet their current expectations.

So, he smiled and replied, I think it’s time for the email migration.

Liza looked confused and asked what’s that?

He replied that this means we need to migrate all our emails to a new platform like Office 365 (Microsoft 365). Jack explained that it is the most popular email platform today. It is used by most organizations, both small and large, because of its amazing features, better spam filters, and many other things.

Liza said, is it safe?

Jack replied, yes, I will make sure everything transfers safely and accurately. Noone will lose their important emails, contacts, calendars, and other data.

Soon he started Rediffmail to Office 365 migration. After some days of careful work, he successfully migrates data of every employee from Rediffmail to Office 365 account.
