@Backmischung,

I hope you're doing well.

I'm able to replicate this issue in my own environment. Specific contacts produce the "GivenName" error, but not to all mailboxes.

2021/03/02 16:40:12 INFO Updating Contact: [email protected]
PS>TerminatingError(Set-EXCContactObject): "The property 'GivenName' cannot be found on this object. Verify that the property exists and can be set."
2021/03/02 16:40:13 ERROR Failed to sync [email protected] contact to [email protected]'s mailbox The property 'GivenName' cannot be found on this object. Verify that the property exists and can be set.

GivenName is one of the properties of the Contact EWS class. You can find more info here: https://docs.microsoft.com/en-us/dotnet/api/microsoft.exchange.webservices.data.contact?view=exchange-ews-api

Since (in my experience) the error only occurs when updating contacts, we know that we're dealing with contact objects fetched from a user's mailbox. You can see the line below from Sync-ContactList.ps1.
$MailboxContacts = Get-EXCContactsObject -MailboxName $Mailbox -Credentials $Credential -Folder $ContactsFolderObject -service $service | Where-Object {$null -ne $_.EmailAddresses[[Microsoft.Exchange.WebServices.Data.EmailAddressKey]::EmailAddress1].Address}

I'll need to do some testing. Unfortunately, I've been busy with other projects and will need some time to come back to this.

Hello again,

just a little update: the error kept persisting but deleting the created folder and initiating a new sync solved the issue (as expected).

A way to remotely deleting the created folder would be a nice tool for troubleshooting in general.

Best regards

Update: The same error keeps occuring.
Deleting the synced folder is just a temporary solution, also hard to keep up with multiple mailboxes.

I had same issue with update function, but i noticed it only happens if there is duplicate contact on destination folder.

I just added following if before set-exccontactobject. It's not pretty, but does following and doesn't crash to "Given name" error.

If more than one contact found with same email addres, this picks first one and deletes it and update second one.

For some reason it just delete on first run and update on second run. But without "$ContactObject = $result2" job crashes. So, it's not pretty and may need tweaking, but working its own ugly way ;)

###edit. Replaced - first 2 to - last 1 😉

write-host "Contact count on contacts folder with same email address $kontaktiwindowsemailaddress :" $ContactObject.count

Delete if double"

if ($ContactObject.Count -gt 1){

$result = $ContactObject | select-object -first 1

$result2 = $ContactObject | select-object -last 1

write-host "Duplicate found, deleting $result"

$result.Delete([Microsoft.Exchange.WebServices.Data.DeleteMode]::SoftDelete)

$ContactObject = $result2

}

try {

Set-EXCContactObject -MailboxName $Ma....

@wayfarerfin Thanks for explaining this issue and writing out some sample code to fix it. I just addressed this in the last commit 7cb0b30. Please update and see the changelog for more information.
