Adjusting the Send/Receive Frequency #

Adjusting Outlook’s Send/Receive schedule can often improve performance. If email messages are slow showing up in your Inbox, you can configure Outlook to send/receive messages more frequently so that it doesn’t have to download as much data each time it checks for new messages. If your send/receive schedule is set to check less-frequently, say, every 30 minutes, try changing it to send/receive every 3 minutes.

Microsoft Outlook users can find this setting via File | Options | Advanced. Locate the Send/Receive section and click on the Send/Receive button. Then, under Send/Receive Groups | All Accounts, adjust the timing for “Schedule an automatic send/receive every…” as shown here:

Compacting a PST in Outlook #

PST files can be another source of Outlook sluggishness. You can help improve Outlook’s performance by:

1. Using multiple PST files.
2. Keeping attachments out of PST files.
3. Compacting PST files.

To compact a PST file in Outlook 2010, 2013 and 2016:

1. Delete any items you no longer need, and then empty the Deleted Items folder.
2. Click on the File tab on the ribbon, and then select the Info tab.
3. Click on Account Settings, and then click on Account Settings again.
4. Click on the Data Files tab.
5. Select your PST file in the list, and then click on Settings.
6. On the General tab, click on Compact Now.
7. Click on OK and Close.

Sometimes, your PST files can develop errors or data inconsistencies, resulting in unexpected behavior in Outlook. When you suspect that there’s an issue with the integrity of your PST file, you can run Scanpst.exe to repair your PST files.

Scanpst can be tricky to locate. By default, you should be able to find it in the Program Files | Microsoft Office | Office16 folder, but you may need to perform a search if you can’t find it in its default location. This location may vary depending on which version of Outlook you are using. You may also want to create a shortcut to this file on your desktop for easier access.

Before using this tool, we recommend making a backup copy of your PST file in case any errors or file corruptions occur to the original file. This shouldn’t be an issue, however, because if Scan PST finds any errors, it will prompt you to make a backup before attempting to repair the file.
