Important change to EWS access to Microsoft Teams data

Microsoft have annouced they will be restricting access to Microsoft Teams data via EWS from the 30th September see https://devblogs.microsoft.com/microsoft365dev/restricted-access-to-microsoft-teams-data-via-ews-starts-september-30-2022/ . If you are using EWS to access any teams data you will need to move to the Graph API's https://docs.microsoft.com/en-us/microsoftteams/export-teams-content one thing to note is "Microsoft Teams APIs in Microsoft Graph that access sensitive data are considered protected APIs" so there are some extra steps and time you need to access this data and be aware of the potential need to pay for that access eg "On July 5th 2022, metered consumption is active, and will be billed through an Azure subscription" ref https://practical365.com/teams-export-graph-apis/.
