Hi everyone.
We are a small UK company, part of a European Group recently moved from Lotus Notes to O365. All companies synchronize their AD with the Group AD servers which in turn synchronise with Micrososoft.
We all use O365 Pro with E3 licences
I have two mailboxes, my own and the general IT mailbox. Up until very recently, including the changeover to a new laptop, I have been able to send emails to individual addresses, internal & external and also distribution groups, again internal
and external, whilst in the office and at home working on my VPN from both mailboxes.
I now cannot send from my IT mailbox, despite having full access rights but can from my own mailbox
The error I get is as follows:
Your message did not reach some or all of the intended recipients.

The following recipient(s) cannot be reached:

This message could not be sent. Try sending the message again later, or contact your network administrator. Error is [0x80070005-00000000-00000000].
This, when googled is pretty vague. I cannot change anything on an Exchange server because it is hosted.
Can anyone assist me please?
Many thanks. kind regards, Nick
