Troubleshooting:

If you are unable to add a mailbox, these could be some reasons:

  • The administrator might not have permitted access. If so, contact them for further instructions and assistance.
  • You entered an incorrect name for the mailbox; again, contact your administrator.
  • The password has expired. If you have access to Outlook Web Access, try signing in and update your password then try signing in again.
  • If you are an Office 365 user, make sure a license is assigned to your account to access the mail server.

    Can you powershell this?

    Thanks for this great page. A little quibble: Bullet 8 should read Apply and OK, instead of Add and Apply. Does not take away from the value of the page.

    I am trying to find out how I can create an additional Outlook profile for another Office365 user. Whenever I try it, it is always prompting me for the other user’s username and password. Previously where we were onsite Exchange it did not prompt. We utilize this for setting our subordinate’s OOO replies and other rules.

    What steps do I take if I am having a syncing issue. It appears that we have current bills mailed to a specific mailbox, however I only have the ones from November. I also just recently updated office 365, not sure what other step to take.

    Good instructions. Thank you.

    About two months ago, we added another email to Outlook with the sales rep from ATT telling us the our old email would stay open forever. Not quite. When you move off Roadrunner (Spectrum) they kill your old email. So now I have two different Outlook files and would like to combine them and kill off the old email address. But how do you combine these files?

    • Hi Edward,

      Have you tried to just drag and drop your email from one Mailbox/File into the other? That’s how I usually combine mailboxes and/or PST files.
