Delete meeting invite

Question

Hi all

I want to delete recurring meeting requests for one user mailbox.
For example mailbox is user1@Company portal .com and Meeting Subject is TEST and the meeting owner is user1 itself. How do i delete it as search mailbox is depreciated. Experts guide me

Answer 1

Have you tried delegating admin or other user permission to manage user1's calendar then cancel it?

Add-MailboxFolderpermission -Identity user1@contoso.com:\Calendar -User admin@contoso.com -AccessRights PublishingEditor  

In addition your script above about -ExchangeLocation and -ContentMatchQuery '(Subject:"TEST") AND (To:"user1@Company portal .com") '

The ExchangeLocation parameter specifies the mailboxes to include. Valid values are:

A regular user mailbox. Including other types of mailboxes (for example, inactive mailboxes or Microsoft 365 guest users) is controlled by the AllowNotFoundExchangeLocationsEnabled parameter.

A distribution group or mail-enabled security group (all mailboxes that are currently members of the group).

The value All for all mailboxes. You can only use this value by itself.

Answer 2

Deleting meeting requests is not a good idea, it's best to Cancel them instead. But you can only do that via EWS, and the user account must still exist.

In any case, if you want to just delete items, follow the procedure here: https://learn.microsoft.com/en-us/microsoft-365/compliance/search-for-and-delete-messages-in-your-organization?view=o365-worldwide
