To restore the standard inbox in classic Outlook for Windows, open the affected folder and choose View › Reset View › Yes. If you want the familiar compact message list, choose View › Change View › Compact. In new Outlook or Outlook on the web, adjust Settings › Mail › Layout instead; those versions do not have the classic Reset View button.
Start with the section that matches what changed. A missing reading pane, larger text, grouped conversations, and a switch to new Outlook have different fixes. Resetting a view changes its presentation; it does not delete your messages.
Reset the inbox in classic Outlook
- Open the mail folder that looks wrong, such as Inbox.
- Select the View tab.
- Choose Reset View, then Yes. This discards custom settings for the current view, so note any column or sorting choices you want to keep first.
- If needed, choose View › Change View › Compact. Single and Preview are other layouts, so a reset alone may not select the layout you remember.
- Open a message and check the list, sorting, and reading pane before changing other folders.
The folder goes back to its default layout. According to Microsoft, the default Inbox view in classic Outlook is Compact, with messages grouped by conversation.
If Reset View is unavailable, check which view is selected under Change View. You can also open Change View › Manage Views, select an applicable built-in view, and use Reset if offered. An unavailable button does not mean that every pane, font, or layout setting is already how you want it.
Reset View is also the quick way back after adding columns such as Received to copy Outlook emails into Excel.
Once the folder looks right, use View › Change View › Apply Current View to Other Mail Folders to choose other folders that should match. Leave folders with intentionally different layouts unchecked. Microsoft explains how Outlook views work.
Restore a missing pane or change text size
Reading pane: In classic Outlook, choose View › Reading Pane › Right or Bottom. Off hides the preview; it does not remove the email. See Microsoft’s reading pane options.
Folder list: Choose View › Folder Pane › Normal. Expand your mailbox or folders if only their headings appear. For a specific missing folder, see where to find the Outlook Outbox.
Collapsed ribbon: Press Ctrl + F1 or double-click a ribbon tab to expand it. This affects the command area, not your inbox view.
With the ribbon back, an open message shows the Format Text tab again, where you can strikethrough text in Outlook and change fonts.
Small message-list text: In classic Outlook, open View › View Settings › Other Settings and adjust Row Font or Column Font. If only the opened message is too small, adjust its reading zoom instead. These are separate controls, and changing the font size in Outlook covers them in more detail.
Undo other common changes in classic Outlook
- Messages grouped into threads: on the View tab, clear Show as Conversations and choose whether to apply it to this folder or all mailboxes. On the web, Outlook.com has its own switch to stop grouping messages by conversation.
- Too many or too few preview lines: select View › Message Preview and choose Off, 1 Line, 2 Lines or 3 Lines.
- Columns instead of a two-line list: select View › Change View › Compact. Single and Preview are list views with columns.
- Ribbon buttons missing or rearranged: go to File › Options › Customize Ribbon and use Reset › Reset all customizations. This affects only the ribbon, not the inbox view.
Change the layout in new Outlook or Outlook on the web
- Select the Settings gear, then Mail › Layout.
- Under the reading pane options, choose the position you prefer, such as right or bottom.
- Under message organization, choose individual messages if you do not want replies grouped into conversations.
- Under Focused Inbox, choose whether to split mail into Focused and Other. Select the option not to sort your messages if you want one list.
- Select Save if shown, close Settings, and check the inbox.
Microsoft also lists a Message list format option here to show the sender name or the subject first. That is separate from the From line in a message you are writing, which you turn on by showing the From field in Outlook.
For spacing, look on the View tab for Density and choose a roomier or more compact option. For messages in the wrong order, use the message list’s Filter or sort control and check the sort field and direction. Layout changes do not recover deleted mail; if messages seem missing, clear an active filter and check both Focused and Other first.
Microsoft’s help pages cover the message list settings and the web mailbox appearance controls in more detail.
Switch back if the whole app changed to new Outlook
If you want the classic application itself, use the new Outlook toggle at the upper right and choose Switch back to classic Outlook. Some versions also offer Help › Go to classic Outlook. An option to use classic only this time is temporary; choose the switch-back option if that is your intention.
If the toggle is missing, search Windows Start for Outlook (classic). Classic Outlook must be installed and available under your license. A work or school policy can also control switching, so contact your IT team when the option is restricted. See Microsoft’s switch-back instructions. Reset View cannot turn the new application into the classic one.
If classic Outlook isn’t on your PC at all, here’s how to reinstall Outlook on Windows 11.
Reset all classic Outlook views only if necessary
If several folder views remain broken, classic Outlook has a broader reset command. This removes all custom views you created. Take screenshots or notes of settings you need to rebuild before using it. For one affected folder, try its Reset View button first.
- Close classic Outlook.
- Press Windows + R.
- Enter
outlook.exe /cleanviewsand press Enter. Keep the space before the slash.
outlook.exe /cleanviews with a space before the slash. This recreated Run dialog is an inert example: the switch restores default views and removes custom views, so use it only for the reset described above.- When Outlook opens, check the affected folders and reapply any custom layout you still need.
Microsoft’s switch list spells out what the /cleanviews command affects. It restores views, not account passwords or deleted messages, and these instructions are for classic Outlook on Windows.
If the layout changes again after restarting
First check whether only one folder looks different: each folder can use its own view. Also maximize the window; a narrow message list can display differently. If the problem keeps returning, close Outlook completely, reopen it, and install available Office updates.
For classic Outlook, you can test whether an add-in is involved: close it, press Windows + R, enter outlook.exe /safe, and press Enter. Safe mode also changes some display behavior, so use it as a diagnostic step. If the problem disappears, review File › Options › Add-ins and test disabled COM add-ins one at a time rather than removing them all. Follow Microsoft’s Outlook troubleshooting guidance, or ask IT for help on a managed PC.
If classic Outlook won’t start at all, work through these fixes for when Outlook won’t open instead.
If only the calendar view changed
Open Calendar and select Day, Work Week, Week, or Month from the available calendar controls. In classic Outlook, View › Reset View can also reset an applicable calendar view. Changing the calendar display does not change your appointments.
Frequently asked questions
Will resetting the view delete any emails?
No. Reset View and /cleanviews change how messages are displayed, not the messages themselves. If mail seems missing, check for an active filter and look in both Focused and Other. Older messages may also have been moved by AutoArchive, and archiving old emails in Outlook shows where archived mail goes.
Why does only one folder look different?
Each folder can keep its own view. Fix the one that looks right, then use Change View › Apply Current View to Other Mail Folders.
Why is Reset View grayed out?
The current view may already be at its defaults, or you may be using a custom view. Choose a built-in view under Change View first, or use Manage Views.
How do I get the classic Outlook look back after an update?
If the whole app changed, use the toggle to switch back to classic Outlook. If only the layout changed, adjust Settings › Mail › Layout in new Outlook. If the app also started making noise, here is how to turn off the new email sound in Outlook.
