My sent emails are showing the following in the "From" field instead of my name or email address:

/o=First Organization/ou=Exchange Administrative Group(FYDIBOHF23SPDLT)/cn=Recipients/cn=00030000BCEA030F

I've tried all of the options suggested for this problem, but nothing is resolving the issue.

Outlook | Windows | New Outlook for Windows | For home

    Hello Carl Lincoln, thank you for posting this in the community.

    Have you tried to recreate the Outlook profile. ?

    If not give it a try, Please close Outlook first, then open Control Panel and select Mail, followed by Show Profiles. Choose Add to create a new profile and configure the mailbox, then set the new profile as the default. After that, launch Outlook and test the behavior.

    Recreating the Outlook profile resolves most cases that are caused by hidden MAPI or profile‑level corruption.

    Kind regards,

    John Oli
