s. Ask them to check that any forwarding they've set up is working correctl=
y.
* Clear the recipient Auto-Complete List in Outlook or Outlook on the w=

ror code 5.1.10 in Office 365<https://go.microsoft.com/fwlink/?LinkId=3D532=

More Info for Email Admins
Status code: 550 5.1.10
This error occurs because the sender sent a message to an email address hos=
ted by Office 365 but the address is incorrect or doesn't exist at the dest=
ination domain. The error is reported by the recipient domain's email serve=
r, but most often it must be fixed by the person who sent the message. If t=
he steps in the How to Fix It section above don't fix the problem, and you'=
re the email admin for the recipient, try one or more of the following:
The email address exists and is correct - Confirm that the recipient addres=
s exists, is correct, and is accepting messages.
Synchronize your directories - If you have a hybrid environment and are usi=
ng directory synchronization make sure the recipient's email address is syn=
ced correctly in both Office 365 and in your on-premises directory.
Errant forwarding rule - Check for forwarding rules that aren't behaving as=
expected. Forwarding can be set up by an admin via mail flow rules or mail=
box forwarding address settings, or by the recipient via the Inbox Rules fe=
ature.
Recipient has a valid license - Make sure the recipient has an Office 365 l=
icense assigned to them. The recipient's email admin can use the Office 365=
admin center to assign a license (Users > Active Users > select the recipi=
ent > Assigned License > Edit).
Mail flow settings and MX records are not correct - Misconfigured mail flow=
or MX record settings can cause this error. Check your Office 365 mail flo=
w settings to make sure your domain and any mail flow connectors are set up=
correctly. Also, work with your domain registrar to make sure the MX recor=
ds for your domain are configured correctly.

<em>Status code: 550 5.1.10</em>
<br />
<br />This error occurs because the sender sent a message to an=
email address hosted by Office 365 but the address is incorrect or doesn't=
exist at the destination domain. The error is reported by the recipient do=
main's email server, but most often it must be fixed by the person who sent=
the message. If the steps in the <b>How to Fix It</b> section above don't =
fix the problem, and you're the email admin for the recipient, try one or m=
ore of the following:<br /><br /><b>The email address exists and is correct=
</b> - Confirm that the recipient address exists, is correct, and is accept=
ing messages.<br /><br /><b>Synchronize your directories</b> - If you have =
a hybrid environment and are using directory synchronization make sure the =
recipient's email address is synced correctly in both Office 365 and in you=
r on-premises directory.<br /><br /><b>Errant forwarding rule</b> - Check f=
or forwarding rules that aren't behaving as expected. Forwarding can be set=
up by an admin via mail flow rules or mailbox forwarding address settings,=
or by the recipient via the Inbox Rules feature.<br /><br /><b>Recipient h=
as a valid license</b> - Make sure the recipient has an Office 365 license =
assigned to them. The recipient's email admin can use the Office 365 admin =
center to assign a license (Users > Active Users > select the recipie=
nt > Assigned License > Edit).<br /><br /><b>Mail flow settings and M=
X records are not correct</b> - Misconfigured mail flow or MX record settin=
gs can cause this error. Check your Office 365 mail flow settings to make s=
ure your domain and any mail flow connectors are set up correctly. Also, wo=
rk with your domain registrar to make sure the MX records for your domain a=
re configured correctly.<br /><br />For more information and additional tip=
