Problem
Calendar entries are migrated in the wrong time zone
Solution
Ensure your users have the correct time zone set for their calendars (source matching destination).
If migrating to Exchange / Microsoft 365
In the rare case that the time zone is not present in the migrated event(s) you should configure the correct time zone in Destination Platform Settings / ‘Exchange/Office 365 Calendar Timezone’, to avoid any possible mismatch.
If migrating to Google Workspace
You should configure Destination Platform Settings / 'Default Calendar Timezone', which will apply the configured time zone in case a time zone is not found when migrating appointments from the source.
