When we migrate your calendar as part of a migration from Microsoft365, or from another Google account, here's what you need to know. 

Where possible, our systems will maintain the links for invites and the people you invited. 

Sometimes this isn't possible, such as with repeating calendar meetings. The iCal format (the standard for calendar entries) doesn't keep information on the invitees and their status for every single occurrence and as such, you will need to recreate your standard team meetings and those with external parties.
