I’ve had this issue before and I did resolve it, once I troubleshooted it showed that this is not an issue with the activity, its on your mail service provider.
The thing is that newly created mailboxes will give you the the string showed at your image, while the old mailboxes will give you the right mail address.
To resolve your issue, contact your mail administrator to provide you the legacyExchangeDN attribute value of an old mailbox, you’ll find a fixed prefix prior to “/CN=RECIPIENTS/CN=…”.
Now you’ll need to check if the mail address starts with “/”, then add the fixed prefix prior to the string, if not, then dont make any action on the mail address.
I’ve never faced this issue, can you give more details on how you extract the email address value? do you use Get Outlook Mail Messages? or just share a screen shot of a null value shown.
Hi @crowdo,
Were you able to find a solution to MailItem.From address being shown as null?
Having the same issue on a newly setup client machine for me.
Thanks
