Why can’t I connect to my account from my mobile device or desktop e-mail program after resetting or changing my password?
You need to update the password value in the settings on your mobile device or desktop e-mail program (for example, Apple Mail, Mozilla Thunderbird, Microsoft Outlook, or Windows Live Mail) each time your password changes.
To resolve this, make sure that the password entered on your mobile device settings or desktop e-mail program settings matches the most current password that you use to sign in to Outlook Web App. For more information, see Update the password setting on your mobile device and desktop email programs after changing your Office 365 password.
As a person that manages accounts for my company, what do I need to know before I reset a user password?
When you reset a user’s password, the user needs to update the password setting on any mobile devices or desktop e-mail programs that they use to connect to their accounts. We recommend that you notify your users of this requirement. For information, see Update the password setting on your mobile device and desktop email programs after changing your Office 365 password.
I’m trying to access my mailbox at mail.office365.com. If I use http://mail.office365.com, it works fine. But if I use https://mail.office365.com, I get certificate errors. What’s wrong?
You can’t use https with mail.office365.com. Even though the URL starts with http, you are immediately redirected to use https for the entire session, including authenticating and accessing your mailbox in Outlook Web App. For more information about Exchange Online URLs, see Configure Sign-In URLs for Outlook Web App.
Do you support a catch-all mailbox that accepts all incoming mail for invalid e-mail addresses?
No, we don't support a catch-all mailbox.
How do I set up conference rooms or other facilities to accept meeting requests?
Exchange Online uses resource mailboxes to provide a centralized calendar to manage reservations for things that people want to use. There are two types of resource mailboxes:
Room mailboxes Use these for physical locations, like conference rooms, auditoriums, and training labs. To create room mailboxes:
Equipment mailboxes Office 365 for enterprises admins can use Windows PowerShell to create equipment mailboxes for items that don’t have a physical location, such as portable computers, audio-visual equipment, or vehicles. For details, see Create Equipment Mailboxes.
After you create a resource mailbox, users can immediately create conflict-free reservations for the room or equipment. However, if you want to refine who can reserve the resource, when they can reserve it, and for how long, there are many options available to fine-tune the resource mailbox and the reservation process. For more information, see Configure Resource Mailbox Options. Remember: after you create a resource mailbox, it’s added to the Mailboxes list in the Exchange Control Panel: Manage My Organization > Users & Groups > Mailboxes.
How do I set up a meeting? Users can set up meetings using the Scheduling Assistant. In Outlook or Outlook Web App, just create a new appointment or meeting request, and then click the Scheduling Assistant tab. And users can reserve a room by creating a meeting and including the room mailbox. For details, see Select a Meeting Room.
