But am not able to login on my exchange account on my windows client (see screenshots) I hope someone can help me.

Hi, I am having all weird issues trying to get my home laptop to configure an Outlook (M365 apps) account to connect to our work on prem Exchange. It times out as if it can't talk to the Exchange server. I created a new computer profile then tried, it actually worked, I could see my mailbox, send and receive email. Later I deleted the profile, tried again in the same local computer profile, it failed with the same behavior as above. When I do an 'nslookup austodiscover.mydomain.com.au' it resolves correctly to WAN IP where our server is located behind. Other people have no issue connecting externally, so there's nothing wrong with the firewall or server communicating with external Outlook clients. My work computer connects fine on the LAN. I brought my home laptop into the LAN, it still doesn't work. DNS issue right? Well, as mentioned, the autodiscover nslookup works and I don't have any other weird DNS related issues. There's just something really flaky going on with my computer.Sky8BlueJul 14, 2025Copper Contributor542Views0likes11Commentscannot add Exchange Mailbox to Outlook for MAC and native Mail app
Hi, We have a strange problem for a few days. The client has Exchange Server 2019 on-premises. The problem is suddenly email stopped delivering to the mailbox which was added to Outlook for MAC or the native macOS mail app. No problem with mailboxes configured on iPhone or Outlook for Windows. Today I tried to troubleshoot the problem on another MAC computer. I cannot add an Exchange mailbox to Outlook for MAC or Mail app. "couldn't verify username or password". Password is fine since I can log in to OWA. I was also able to configure the same mailbox on an iPhone or Outlook for MAC. I think for some reason MAC is more strict or a DNS resolution with the certificate is the problem. I ran the MS Analyzer Connect test and the output is fine. Any idea why we cannot add an Exchange mailbox in MAC? IMAP is also not working.

Greetings everyone, I am currently trying to get ModernAuth running in conjunction with Exchange 2019.

Tools and re-install them?
I have a single Exchange 2016 server (CU 23) that in a hybrid configuration with M365. Something has happened and now I can't use Exchange Mgmt. Shell on the Exchanger Server. ("CannotConnect,PSSessionOpenFailed" is the ultimate error I see in the PS window when I launch it) As a work-around I install the mgmt tools on another server (non-Exchange) and am successful in connecting to the exchange server with Exchange mgmt shell remotely. I would like to remove and reinstall the management tools on the server to try and resolve this issue. Presently, I'm not getting good backups so this is rather important. (my backup SW needs to connect to exchange server via PowerShell) When I launch the CU 23 setup process the option to remove management tools is greyed out. (coincidentally so is the option to install Edge transport role which isn't installed) What is the best course of action to attempt to remove and reinstall the exchange management tools? Since this is a hybrid setup I'm a bit concerned about doing anything that could break it. Since this is a VM in Azure, I could deploy a second Exchange Server and move all the mailboxes to that server so I could at least get good backups of the mailboxes. Not ideal, but an option. Thanks.TechRoosterJul 11, 2025Copper Contributor537Views0likes2CommentsConverting smtp email
