IMAP connection showing from_=[{'email': 'MISSING_MAILBOX@MISSING_DOMAIN'}] when sending emails

[0aprl1]

Hello, I am having troubles sending emails via IMAP connection. In particular going through the IMAP flow on Nylas-hosted UI, I manually set IMAP and SMPT, it confirms connection but then when sending an email it only lands in Sent, the recipient is not getting any email. Looking at the email via Nylas client I see the from to have MISSING_MAILBOX@MISSING_DOMAIN.

I have tried connecting to a standard email client on my computer with same settings and everything works fine, even sending.

Here is the latest grant ID we tried to connect and send emails with -

Has anyone ever had such issue?

Thanks in advance for the support,
