Outlook is an email service provided by Microsoft. Outlook users have reported issues with sending and receiving emails while their computer is in sleep mode. In some cases, Outlook may not connect to the internet after the computer wakes up from sleep mode. In other cases, scheduled emails may not send until the computer is woken up from sleep mode. There are several potential solutions to these issues, including switching to a wireless connection, modifying the Windows registry, and deleting large attachments.

What You'll Learn
Outlook emails may remain in the Outbox folder until manually sent
When you send an email in Microsoft Outlook, the message may remain in the Outbox folder until you manually initiate a Send/Receive operation. This can be done by pressing F9 or selecting Send/Receive. This issue can occur if the "Send immediately when connected" option is not enabled. This setting can be configured by the administrator through a modification of the registry.
In some cases, Outlook emails may not send if your computer is asleep or if Outlook is not running. This can be a problem for users who want to send emails during the night while they are asleep, as the emails will remain in the Outbox folder until the computer is turned back on and Outlook is reopened.
To resolve this issue, users can change their Windows settings so that their computer never goes to sleep. However, it is important to note that this may have an impact on energy consumption and computer performance. Alternatively, users can schedule their emails to send at a specific time, ensuring that their computer is turned on and Outlook is running at that designated time.
It is worth noting that the "Send immediately when connected" option is tied to specific registry data. The registry key path for this setting includes

Outlook may not connect to the internet when a computer wakes from sleep mode
To resolve this issue, you can try unchecking the "turn off device to save power" option in the power management settings for your network card. Additionally, you can try updating your drivers, including BIOS, Network, and Power drivers, as suggested by some users. It is recommended to consult official support channels or an IT professional for specific instructions and further troubleshooting steps.
Another potential cause for Outlook not connecting to the internet after waking from sleep mode could be related to the Outlook application itself. In some cases, Outlook may require a restart to re-establish the connection. This issue seems to be more prevalent when the computer is left signed in but locked, as reported by an upper management user.
Furthermore, there might be a delay in sending and receiving emails when the computer is in sleep mode. Scheduled or delayed emails may not be sent until the computer is actively turned back on. This could be due to Outlook's settings or limitations with the computer's power management. To ensure timely delivery of emails, it may be necessary to keep the computer awake or use alternative methods, such as server-side scheduling or third-party email automation tools.
To summarize, Outlook may not connect to the internet when a computer wakes from sleep mode due to network connection interruptions or application-specific issues. Resolving this may involve adjusting power and network settings, updating drivers, or restarting Outlook. For ongoing issues, it is recommended to seek official support or consult with an IT professional to diagnose and address the specific cause.

A large attachment could be the reason emails get stuck in the Outbox
While there are several reasons why emails may get stuck in the Outlook Outbox, one of the most common is the inclusion of large attachments. This issue is not exclusive to Outlook, as other email clients have similar problems with large files.
In Outlook, this problem can occur when the attachment exceeds the recipient's size limit for incoming emails. The limit varies depending on the email provider and can range from 10 MB to 25 MB or more. If the attachment is too large, the email may remain in the Outbox indefinitely, and you may be unable to send or receive any other messages until the issue is resolved.
There are a few ways to mitigate this problem. Firstly, it is advisable to compress or reduce the size of the attachment before sending it. This can be done by saving the file in a compressed format, such as .zip or .rar, or by using a free online tool to reduce the file size without losing quality. If the attachment contains images, resizing or compressing them can significantly decrease the overall file size.
Another approach is to use a file-sharing service or cloud storage platform to transfer the large files. Services like Google Drive, Dropbox, or OneDrive allow users to upload and share files that are too large to send via email. By uploading the file to one of these services and including a download link in the email, you can avoid the issue of the email getting stuck in the Outbox.
Additionally, it is essential to ensure that your Outlook settings are optimized for sending large attachments. Go to "File" > "Options" > "Advanced" and ensure that the "Attach files" option under "Send messages" is set to "Send large files using the most appropriate method for the recipient's account." This setting will automatically adjust the file size or use a web-based file-sharing service if the attachment is too large.

Emails may not send if the inbox is full
Outlook's outbox allows users to schedule emails to be sent at a later time. However, it appears that the outbox does not work when the computer is in sleep mode. One user reported that scheduled emails did not send while their computer was sleeping and that they had to open their laptop to send the emails.
Regarding the issue of a full inbox, it appears that Outlook will not send or receive new emails if the inbox is full. This is likely due to the limited storage capacity of the email account. In Outlook, each user has a certain amount of storage space for their emails and attachments. If the user exceeds their storage limit, they will not be able to send or receive new emails until they free up some space.
One way to free up space is to delete unnecessary emails or attachments. The user can go through their inbox and delete any emails they no longer need, or move important emails to a different folder to free up space in the inbox. Additionally, the user can consider using a different email service that offers more storage space, such as Gmail.
It is worth noting that the "Send immediately when connected" option in Outlook may also affect the sending of emails. If this option is not enabled, emails may remain in the outbox until the user manually initiates a Send/Receive operation. This setting can be changed by the user or an administrator through a modification of the registry.
To prevent issues with a full inbox, it is recommended to periodically review and delete unnecessary emails and attachments. Additionally, users can consider using an email service with larger storage capacity or exploring other options such as cloud storage for important emails and attachments.

Outlook may not work with a wired connection
In some cases, the issue may be related to the router or network settings. For example, the required ports may be blocked, or there may be an issue with the Automatic Configuration setting. It is also worth noting that some Internet Service Providers (ISPs) may block the SMTP port required to send emails to prevent their customers from being used as open relays for spamming.
To troubleshoot Outlook connection issues, there are several steps that can be taken. One suggestion is to verify that the Outlook send/receive settings are configured for external addresses. This can be done by trying to connect to Outlook at another location, such as an internet cafe. Additionally, if using a laptop, it may be worth trying to connect to Outlook on a different network to see if the issue is specific to a particular network or location.
If the issue is specific to a wired connection, it may be worth checking if other wired users are experiencing the same problem. If they are not, it could indicate an issue with the specific wired network or the switches being used. In some cases, switching to a wireless connection may resolve the issue, as seen in reports where Outlook remains connected when users switch from a wired to a wireless connection.

No, Outlook does not work when the computer is in sleep mode. You will have to manually initiate a Send/Receive operation.
This could be due to a large attachment or because you are not connected to the internet.
First, check if the email has an attachment larger than 25MB. If it does, delete the attachment, attach a smaller file, or upload the file to OneDrive and attach a link. If there is no large attachment, check your internet connection and click Send/Receive.
Try restarting Outlook. If that doesn't work, switch to a wireless connection if you are using a wired one.
