Hi Lyubo​,

Hello RobertSparnaaij​, my post above just got approved.

I am attempting to send you a private message with the account parameters as requested, but the Tech Community website's outbound messaging tool is completely freezing and refusing to submit on my profile page.

Microsoft Support has already verified the backend block under Case Reference 7110532601. Could you please initiate a direct message thread from your end? Once I receive your incoming message notification, I will be able to reply to it instantly with the affected mailbox address that needs the backend ImapRemoteServerInfo purge.

Thank you for your help !
