This article is for Outlook Web App, which is used by organizations that manage email servers running Exchange Server 2013 or 2010. If you're using Microsoft 365 or Exchange Server 2016, your email program is Outlook on the web. For help with Outlook on the web, see Get help with Outlook on the web.
The Messaging options let you configure individual message settings, for example, your email signature or how you want recipient names on a new message to be resolved.
To get to the Message options page from the main Outlook Web App page, go to the upper corner and choose Options, then choose Messaging from the list in the navigation pane.
After you change the settings on this page, select Save to apply your changes.
Number of items to display per page Set the number of email messages or items that will be displayed at a time. By default, 20 items will be displayed at a time. You can set the number of items to be displayed from 5 to 100.
After moving or deleting an item Set this option to select the action you want to be taken after you move or delete a message you have open. When you move or delete a message, you can choose to return to the view, open the previous item, or open the next item. By default, return to the view is selected.
An email signature is text that's automatically added to the end of an outgoing message.
Automatically include my signature on outgoing messages Select this if you want Outlook Web App to include a signature on all of your outgoing messages. The signature you create in Outlook Web App isn’t shared with Outlook. You'll have to create separate signatures if you use both Outlook Web App and Outlook to access your mailbox.
To modify an existing signature, select Replace my current signature with the following, and then enter your new signature in the text box.
You can only use one signature, and it will be applied to all messages. You can’t put images in the signature.
Message tracking options let you control responses to read receipts. You have three options for handling email that has a read receipt.
Ask me before sending a response Select this option if you want to be prompted before sending a read receipt to the sender. By default, a message appears in an information bar that states the sender has requested a read receipt.
Always send a response Select this option if you want to always automatically send a read receipt response to a sender who requests a receipt for a message.
Never send a response Select this option if you never want to send a read receipt response to a sender who requests a receipt for a message.
The email name resolution options let you control how the recipients you add to a message are resolved.
Add recent recipients to the Most Recent Recipients list Selecting this check box adds names that are resolved to the Most Recent Recipients list. The names that are added to this list appear in a selection box in the user interface when you start to type part of a recipient's full name. You can then select that recipient from the list of possible matches. By default, this setting is selected.
Clear Most Recent Recipients list Select this link to clear the Most Recent Recipients list. You'll be prompted to confirm that you want to clear the names from the list before the names are cleared.
When resolving names, check first in This option lets you choose where Outlook Web App checks first to resolve names on the To or Cc lines of a new message. You can use the global address list or your Contacts.
Global Address List Select this option if you want to first use the global address list to resolve a recipient name. If Outlook Web App can't resolve the name in the global address list, it will look in your Contacts. By default, this option is selected.
Contacts Select this option if you want to first use your personal contacts to resolve a recipient name. If Outlook Web App can't resolve the name in your contacts, it will look in the global address list.
When you delete an item, it’s moved to the Deleted Items folder before being permanently deleted. You can choose to automatically delete all items in the Deleted Items folder when you sign out.
Empty the Deleted Items folder when I sign out Select this check box if you want to delete items in the Deleted Items folder when you sign out from Outlook Web App. After you delete an item from your Deleted Items folder, it's permanently deleted.
