Get-MgUserMailFolderMessage : Syntax error: character '0' is not valid at position

[daveschafer]

I try to use the Microsoft.Graph Module to periodically search for specific mails in a mailbox.
When I filter the output with the "Search" parameter, the query breaks when I have characters like numbers or control characters.

This Example Works:

Get-MgUserMailFolderMessage -UserId "mailbox@domain.tld" -MailFolderId "Inbox" -Search 'Backup Config'

And Provides the expected output:

Id                            Subject                                          ReceivedDateTime      HasAttachments
--                            -------                                          ----------------      --------------
RandomIDString                [Success] Backup Configuration Job (1 VMs)       25.09.2020 08:04:28   False

This Examples do not work:

Get-MgUserMailFolderMessage -UserId "mailbox@domain.tld" -MailFolderId "Inbox" -Search 'Backup Config 0'

Get-MgUserMailFolderMessage -UserId "mailbox@domain.tld" -MailFolderId "Inbox" -Search '\'

Get-MgUserMailFolderMessage -UserId "mailbox@domain.tld" -MailFolderId "Inbox" -Search '_'

And provide this error output:

Get-MgUserMailFolderMessage : Syntax error: character '0' is not valid at position 14 in 'Backup Config 0'.
In Zeile:1 Zeichen:1
+ Get-MgUserMailFolderMessage -UserId "mailbox@domain.tld" ...

    + CategoryInfo          : InvalidOperation: ({ UserId = back...ndProperty =  }:<>f__AnonymousType5`10) [Get-MgUserMailFolderMessage_List], RestException`1
    + FullyQualifiedErrorId : RequestBroker--ParseUri,Microsoft.Graph.PowerShell.Cmdlets.GetMgUserMailFolderMessage_List

I am not sure if this behaviour is intended and I could not find any hints to that in the documentation.

However there are some workarounds to get the output i want, but therefore I have to first pull a huge list of mails and filter them afterwards, which is painfully slow

Just found out my issue is tightly related to this one #399

If I quote my double quotes witha single quotes, everything works as expected, e.g.

Get-MgUserMailFolderMessage -UserId "mailbox@domain.tld" -MailFolderId "Inbox" -Search '"Backup Config 0"'

Anyway, it would be nice if the SDK handled this behaviour

This has been fixed in version 1.2.0. Use Update-Module Microsoft.Graph to install the latest version.
