I'm having issues when i need to share documents with my colleagues. They cannot receive the invitation email sent by email@example.com at all.
The email domain i need to send the invitation to is @syeint.com which is actually provided and back-end operated by Tencent, the Chinese giant company with their famous product WeChat and QQ. I tried to send invitations to @qq.com emails and it is all normal, while @syeint.com couldn't receive my invitations at all. I tried to contact Tencent technical support and they found no incoming record at all from firstname.lastname@example.org.
I'm quite frustrated that I can't share my documents with my colleagues so to work on projects together. I have an alternative solution to send invitations to my colleagues' personal emails, but very few of them will want to use personal email for work purpose.
Could I use any help here? Maybe the email server operator of email@example.com can check for me if you have ever sent any invitations to @syeint.com emails today?
Thanks very much!
