Should I use IMAP for migration

In migrating our email from gmail to office 365, I am setting up our gmail account to our Outlook client using the IMAP protocol.  Will that work?  My impression is IMAP just syncs what is on the email server and once the connection is disconnected then we lose access to that information.  Will IMAP produce a PST file or does that happen only with POP3?  Once we do the cutover of services, I don't want to risk losing access to the gmail email because I will need it in order to begin syncing up the emails to the Office 365.


At the end of the day, should I be using IMAP for this purpose, or is POP3 a better option?

This method does not migrate calendar and contacts. Is there another way?

imap will not allow access to calendars or contacts or note either.

neither imap or pop3 have any relationship with PST files. those are a dumb m$-outlook-only buggy way to store email data.

what you are trying to achieve is unclear. are you expecting outlook to to the migration ? or are you expecting both to keep working during the process ?
Thanks this answers my questions
FYI
Previously I was planning to use Outlook to do the migration entirely with the PST file.
