So, I setup a new e-mail account on Office 365. \u00a0For two reasons:
\n1. I like using Outlook and a hosted Exchange instance lets me leverage way more Outlook features than something like Google Apps.
\n2. I am leaving my current job and will be losing my Word, Excel, etc. software when I do.<\/p>\n
It seemed like the best of both worlds, however; after I setup my account in Outlook, all of my test e-mails had a winmail.dat attachment on them.<\/p>\n
I came to learn that this is because Office 365 uses a TNEF format that works great on Exchange and Outlook, but other e-mail servers and clients can get confused by them.<\/p>\n
Some research in Microsoft documentation told me how to change that setting for one domain or one e-mail, as long as that e-mail was in my contacts, but not how to globally change it. \u00a0Luckily I found the answer. \u00a0Use Windows Powershell to login to your Office 365 instance.<\/p>\n
First, run Windows Powershell as an Administrator. \u00a0This is needed to change an Execution policy. \u00a0Then type in:<\/p>\n
Once that is done, you can setup your session using these commands.<\/p>\n This will open a dialog box where you can type in your office 365 username and password. (myusername@mycompany.onmicrosoft.com)<\/p>\n Then: Finally: Now you’re connected. To set the policy for all external e-mails to not use the TNEF format, run this command. Then just to clean things up, run this command This simple set of rules did the trick for me.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" So, I setup a new e-mail account on Office 365. \u00a0For two reasons: 1.
