Hi All,
I’ve performed a lot of Exchange Online Migrations this Year.
After the Mailbox was migrated i did run a Post Migration Script to set some Setting on the Mailbox like:
Set-MailboxRegionalConfiguration -Identity $UPN -TimeZone "W. Europe Standard Time" -DateFormat "dd.MM.yyyy" -TimeFormat "HH:mm" -Language "de-CH" -ErrorAction Stop Set-MailboxCalendarConfiguration -Identity $UPN -WeekStartDay Monday -WorkDays Weekdays -WorkingHoursStartTime 08:00:00 -WorkingHoursEndTime 17:00:00 -WorkingHoursTimeZone "W. Europe Standard Time" -ShowWeekNumbers $True -ErrorAction Stop In some cases there where this Error: “WorkHoursVersion1 is null”

Hi All,
OAuth 2 Authentication for POP and IMAP was announced already back in June 2022 at the Exchange Team Blog.
