Office 365 Connected Accounts

I recently setup Office 365 for a user that has her own domain user@userdomain.com which is her Office 365 account. She also has 2 other email accounts she wanted connected into Office 365 so she could receive and send email all from the one Office 365 account.

However, when she receives email from AOL or Gmail into her Office 365 account via connected accounts, we get the following bounce back:

mx.google.com
Remote Server returned '550-5.7.1 [157.56.110.139 12] Our system has detected that this message is 550-5.7.1 likely unsolicited mail. To reduce the amount of spam sent to Gmail, 550-5.7.1 this message has been blocked. Please visit 550-5.7.1 http://support.google.com/mail/bin/answer.py?hl=en&answer=188131 for 550 5.7.1 more information. 2si3428341pdg.135 - gsmtp'

We are being told by Microsoft that the user must log into her gmail or aol account separately in order to respond to these messages from the desired aol or gmail account which would defeat the whole purpose.

Does anyone have any suggested solutions for this?

There's hardly anything you can do about this, apart from what the support guys advised you. Basically, gmail/aol see that the message claims to be coming from gmail/aol user, but the sender is Exchange Online, so it treats it as spam.

I understand this to be a DMARC issue, but I am looking for any potential solutions to this if any.

Not sure about the OWA client, but Outlook will usually give you a drop-down at the 'from' line when composing a new message.

You can change 'from' to reflect your Office 365 account, but maybe you don't want that...
