Adding shared exchange mailboxes to Win10 Mail App

Question

_{Friday, October 13, 2017 10:15 AM}

Hi,

My office has just moved to use Office 365, and our mailing server to the Exchange. Some of our office have Outlook, so they have it all set up and running without an issue, but I am trying to see how much functionality we can get out of the Win10 mail app. 

So, I have managed to link my own Exchange mailbox to the app without any problems. However, I also have access to some shared mailboxes. In the O.W.A., I can access these by clicking on my user image in the top right corner, selecting "Open another mailbox..." and typing in the desired mailbox. This then uses my user account to check if I have permission, and so then opens the mailbox. 

Is there any similar functionality on the Mail app? If I try to enter that mailbox by adding it in as the email address, but then use my own information as the username and password, it just tries to add another account for my personal email address.

I've figured it out. You've got to use [email protected]\shared-name for the user name, the shared email for the email address and your personal email password. 

However, I couldn't get it to work via your advanced exchange setting, I had to add it through the custom IMAP setting.

EDIT: However, now, I have to keep re-signing into my shared folder every 10mins or so after being informed that my "account settings are out of date". I'd open the dialog box, type in my password again, hit enter and I'm good to go for a while, then I have to repeat those actions again.

Hi,

I configured shared mailbox on mail app with a manual steps on mobile and test the issue on my side. The symptom occurred on your side not appear on my test machine. Every thing works well with my mail app. My test machine is Windows 10 version 1703, and mail application version is 17.8600.40525.0.

At first, please check your configuration steps. Here is what I referred: Windows 10 Mobile – Accessing Office 365 Shared Mailboxes

Please check those version on your side. If it is not the latest, try to update system through Windows Update and test it again.

If the issue persists, check if it could be resolved from mail app re-installation.
