Do final user accounts need office 365 licences to use SMTP server?
Hi, I have an app on Azure AD that requires this scope: https://outlook.office.com/SMTP.SendAsApp from office 365 exchange online API. to access SMTP server, as per documentation (https://learn.microsoft.com/es-es/exchange/client-developer/legacy-protocols/how-to-authenticate-an-imap-pop-smtp-application-by-using-oauth#authenticate-connection-requests). Will my final users account need to have this API licenced?
Exchange 2016 User Mailboxes Migrated to Exchange 2019 | IMAP | SMTP Permission
We have migrated from Exchange 2016 to Exchange 2019 Servers. Exchange 2016 servers have been shutdown now. When I initially setup a new servers, i created a new user and mailbox for each server. Problem: When we configure IMAP Profile in Thunderbird client (windows/Linux) the below happens: 1) new users on new servers - works fine 2) old users who were migrated from 2016 - the issue pops up when sending the email. receiving works fine. The error message is as shown
Receive Connector Parameters for Ubuntu Postfix
Hello, first of all, please excuse me if my wording is off - I usually have nothing to do with Exchange and Servers in general and never have. We are sending mail from a linux server to a recieve connector via postfix. While sending a larger amount of emails at once (lets say 50 different mails to 50 different adresses at once), we regulary get an error and after a few emails the sending process stops. I looked at the settings of our recieve conncetor and noted the following settings, that may be the source of this problem: MaxInboundConnectionPerSource: 20 MaxInboundConnectionPercentagePerSource: 2 So the questions are: 1. Does Postfix establish multiple Connections at once? If so, would our recieve connector stop recieving mails if Postfix establishes more than 20 connections? 2. If at a single time, only this one system sends mails, thus the Connection Percentage of this one source is at 100%, would our connector stop recieving? Thanks in advance and sorry for the unprofessional language.
