ExtendedFolderFlags

Question

We have been trying out the new O365 REST features for some mailboxes. One of the things this article

https://support.microsoft.com/en-us/office/outlook-calendar-sharing-updates-c3aec5d3-55ce-4cea-84b0-80aab6d8dc26

says is that an ExtendedFolderFlag "SharedIn" should appear when checking with Get-MailboxCalendarFolder. But even though the features are active, that specific flag isn't appearing.

But that's another question by itself. Since that "incident" I have been googling for more explanation on these "ExtendedFolderFlags" but I just can't find any. Anyone who has any idea what which flags signify?

I see flags SharedOut, SharedViaExchange, SharedExchangeEver, SharedExchangeWrite, SharedEchangeWriteEver, SharedExchangeValid, ExchangeShareFolder, ExchangePublishCalendar, ...

Answer 1

Hey Tommy. The Powershell part isn't really my problem. I'm just looking for some info on what these different flags actually mean for the user's role/part in Exchange Online.

Answer 2

Hello Jamro,

Thanks for posting into Microsoft Community.

Based on your description, seems you are using PowerShell to ExtendedFolderFlags, nevertheless the specific flag isn't appearing. Regarding this point, we there are some dedicating PowerShell communities PowerShell community support resources - PowerShell | Microsoft Docs, experts in there have abundant experience and knowledge might have some ideas to achieve this feature.

Kind Regards,

Tommy
