Note: The ability to manually repair or rebuild a database is not available in Outlook 2016 for Mac. If a problem such as Outlook data corruption occurs, Office 2016 for Mac automatically repairs and rebuilds the Office database for you. For more information, see.
Before you rebuild the Office database, make sure the problem isn't the result of a damaged or fragmented hard disk. To do so, run a disk diagnostics and repair application, such as Apple Disk Utility.
Hi Diane - I'm running Mac OS 13.2 on a 2015 MBP. All of the the latest updates are in order. Last week Outlook 2016 for Mac (v16.9) suddenly became unresponsive after downloading a series of new emails. Restarting didn't resolve the issue and it persists when rebooting in safe mode.
For more information about how to identify and repair hard disk problems, see the documentation for your disk utility application. Caution: If you have a Microsoft Exchange account, rebuilding the database deletes any information not synchronized with the Exchange Server, including your contacts' certificates. Before you rebuild the database, you might want to back up Outlook data stored only on your local computer. For more information, see.
On the Outlook menu, click Turn Off Office Reminders. Quit Messenger for Mac and all Microsoft Office applications, including Outlook.
Open the Microsoft Database Utility. The default location is in /Applications/Microsoft Office 2011/Office/.
Notes:. You must have read and write permissions for the identity folder to rebuild your database. To check for permissions, select the identity in the /Users/ username/Documents/Microsoft User Data/Office 2011 Identities/ folder and then in the File menu, click Get Info. Check the permissions under Sharing and Permissions. Before the Database Utility rebuilds a database, it creates a backup copy of your database and moves it into a folder in the /Users/ username/Documents/Microsoft User Data/Office 2011 Identities/ folder. The backup copy displays the date and time the backup was created. If your computer has insufficient free disk space to store both your current database and its copy, an out-of-memory error occurs.
For example, if the current size of the database is 10 megabytes (MB), you will need at least 20 MB of free disk space to rebuild or compact the database.
Is a powerful client with a ton of features, add-ins, and integrations that make it perfect for anyone who relies daily on email. Unfortunately, the wide range of tools can hinder Outlook's performance, which is terribly frustrating.
To get you back to your email faster, here are six tips and tricks to boost Outlook performance on Windows 10. Disable add-ins If Outlook is running slow, it almost always has something to do with add-ins. Especially heinous are those from any third-party antivirus you're using — you don't need this add-in, as attachment scanning is already taken care of by your system.
If you aren't using an add-in, there's really no reason not to disable it. Here's how to find your add-ins list and how to disable any you don't need.
Click the Start button. Right-click Outlook 2016. Click More. Click Run as administrator. Click File. Click Options.
Click Add-ins. Click the checkbox next to any options so that the checkmark disappears. This means the add-on has been disabled. If you don't think you'll ever use an add-in, especially in the case of an antivirus, you can remove it completely. Replace step 9 above with the two steps below. Click an add-in you want to remove.
Click Remove. The add-in will no longer appear in your list of add-ins. Disable graphics acceleration Not everyone uses a stellar Windows 10 PC to read their email in Outlook. There is a built-in graphics acceleration feature that may cause freezes and generally poor performance on some machines. Here's how to disable it. Launch Outlook 2016 from the Start menu, desktop, or taskbar.
Click File. Click Options. Click Advanced. Click the checkbox next to Disable hardware graphics acceleration so that a checkmark appears. You might have to scroll down a bit to find this option. Disable RSS feeds Those of you who love to keep up to date with RSS feeds right in Outlook might be compromising its performance. You can disable Outlook's RSS feeds to see if it makes a difference — if you don't notice any changes, you can always re-enable.
Launch Outlook 2016 from the Start menu, desktop, or taskbar. Click File. Click Options. Click Advanced. Click the checkbox next to Any RSS Feed item that is updated so that the checkmark disappears. Click the checkbox next to Synchronize RSS Feeds to the Common Feed List so that the checkmark disappears.
Archive old email If you have a ton of old emails in your main folder, Outlook has to load and process all of them when it opens. Luckily, there is a handy AutoArchive tool built right in that can process old emails. These old emails will be saved in an Outlook PST data file that can be accessed anytime. Launch Outlook 2016 from the Start menu, desktop, or taskbar. Click File. Click Options.
Click Advanced. Click AutoArchive Settings. Click the checkbox next to Run AutoArchive every X days. Click the up or down arrows next to the frequency you want AutoArchive to run.
Click the up or down arrows next to the age of emails you want to archive. You can also experiment with the rest of the AutoArchive settings if you aren't satisfied with the defaults. Compact your PST files Your Outlook PST files keep messages and other info saved safely on your PC. When you delete emails, the space they took up remains — this space will continue to grow until it reaches 20% of the total size of the file. When it reaches this point, Outlook, when running, will automatically start compacting the file. If you've just deleted a ton of emails, you might want to compact your PST files immediately without waiting. Launch Outlook 2016 from the Start menu, desktop, or taskbar.
Click File. Click the dropdown arrow next to Account Settings. Click Account Settings. Click the Data Files tab near the top of the window. Double-click the PST file. Click Compact Now.
This process might take awhile. Click OK when the process has finished. Update Outlook and Windows 10 If Outlook and Windows 10 aren't up to date, you might experience a negative effect to performance. First, update Windows 10.
