Can you check if the SMTP address you are providing is correct?

Usually SMTP is used for sending E-Mails. IMAP, POP3 or the other getxxx activities are used for Mail retrieval.

Can you have a Check on the used Activity and used settings as Well.

Get exchange mail message is working fine when i try to read my inbox, But the movement i try to read shared mailbox it gives SMTP error.

Can I have a view on the property panel of get exchange mail activity if possible with a screenshot
Cheers @sunny1

I have the same issue. Have you figured out what the issue was? Thanks in advance.

Solution to this issue will be to use full email address for the sharedmailbox property.

I had similar issue and in the sharedmailbox property. I entered full email address ( and it fetched the proper emails.

Good luck…!

I was also facing some issues accessing the e-mails from a shared mailbox by the Get Exchange Mail activity. I solved it by filling in the properties like this (sea screenshot).
