Apple Mac Mail Not Working
Apple Mac Mail is built into macOS, the Apple Mac computer operating system software, so when Apple Mac Mail is not working, it is not possible to update the Apple Mac Mail software application directly. If Apple Mac Mail is not working, then modern email systems from Google with Gmail, and with Microsoft for Outlook and also with Microsoft Exchange when used with Apple Mac Mail, do need a minimum version of macOS for Apple Mac Mail to work. macOS Monterey and newer versions of macOS including macOS Ventura, macOS Sonoma, macOS Sequoia, macOS Tahoe, and the upcoming macOS Golden Gate are fully supported to work with modern email systems. However, if you have 5,000 or 10,000 or more emails, then you will find that Apple Mac Mail might not be the best Apple Mac computer email client software to use. Keith Thomas provides expert help when Apple Mac Mail is not working on Apple Mac computers and is available in London and the South East UK to help.
Apple Mac Mail not sending messages
Apple Mac Mail uses SMTP to send email messages, and if you have updated the email password for your email account online and you have not updated Apple Mac Mail, then Apple Mac Mail will not send your email messages. Or if your email service provider has done an email service update, or your email account needs to be re-authenticated, then Apple Mac Mail will not send any email messages until the account settings have been fixed and resolved. If you use either a Google Gmail account or a Microsoft 365 or Outlook.com account, then this is now done with the help of a popup in either Apple Mac Safari, Google Chrome, or Microsoft Edge for Mac depending on the web browser that is used. Also, Apple Mac Mail will not send emails that have large attachments or unsupported file types. However, if you use the Apple iCloud service, you can use iCloud to send emails that have large attachments.
Apple Mac Mail not receiving new messages
Apple Mac Mail will not receive new email messages if the Apple Mac Mail email account is offline, or the email account has the wrong password or incorrect email settings, or Apple Mac Mail needs to be re-authenticated by signing into the email account online, or by making sure that the email password is correct.
Apple Mac Mail not syncing with iCloud Mail
Apple Mac Mail usually works with Apple iCloud Mail as Apple Mac Mail has no settings that need to be set up and it is a one-click solution to get Apple Mac Mail to work with iCloud Mail. However, if iCloud email is not working with iCloud Mail, then one of the first tasks is to make sure that the Apple Account used with the iCloud email address has enough free storage space, as iCloud Photos, iCloud Drive, and even Apple iCloud iPhone backups take up iCloud storage space. If iCloud storage is full or nearly full, then Apple Mac Mail will not sync with iCloud Mail. Apple Mac Mail troubleshooting for iCloud Mail is usually a task of switching iCloud Mail off, waiting a few minutes, and then switching it back on again. This can often resolve the issue of Apple Mac Mail not syncing with Apple iCloud email.
Apple Mac Mail not syncing with Microsoft 365 Exchange – Outlook Mail
If Microsoft 365 or Microsoft Outlook email is not syncing with Apple Mac Mail, then this is often caused by having outdated settings set up in Apple Mac Mail, and Microsoft 365 or Outlook emails seem to be offline. If you have all of your emails online including the sent emails, emails in the Inbox, and emails in folders, then you can remove the email account from Apple Mac Mail and add the account by choosing the Microsoft Exchange option only, as adding the email account any other way no longer works. If you have emails that are in Apple Mac Mail in the “On My Mac” section, then they will have to be exported before removing the Microsoft 365 or Outlook account from Apple Mac Mail. If you are using Apple Mac Mail with a Microsoft 365 Exchange account, then make sure that your Microsoft 365 account is working online by logging into your Microsoft 365 email account via webmail.
Apple Mac Mail not syncing with Gmail
Google Gmail works with Apple Mac Mail, but Apple Mac Mail might not be the best email application client to use, especially if you have more than 10,000 emails or you have multiple email accounts set up in Apple Mac Mail. If you do have more than one or a few Gmail accounts set up using Apple Mac Mail, then you will often see the message “Downloading Messages” all of the time. This is caused by the Gmail account settings and how Google Gmail works with Apple Mac Mail. You can adjust the Gmail settings online to help with Apple Mac Mail not syncing with Gmail Google email accounts. If you have multiple Google Gmail accounts or you have more than 5,000, or 10,000, or even more email messages, then you might want to consider using Google Gmail online or use another email client software application. Microsoft Outlook for Mac, the new non-legacy version, works best if you have a lot of Gmail messages or Google Gmail accounts.
Apple Mac Mail not downloading message content
If Apple Mac Mail is not downloading messages and not showing all email, and some emails are showing, then the Apple Mac Mail database index needs to be resolved. With macOS and the newer versions of macOS, Apple Mac Mail has a basic way to help repair Apple Mac Mail application settings. However, in most cases Apple Mac Mail cannot work after a macOS update or after a macOS upgrade as the internal email database is upgraded. If an Apple Mac computer has an unstable storage system or the Apple Mac computer ran out of storage during a macOS update or a macOS upgrade, then the Apple Mac Mail internal database can be damaged. If you have all of your emails online and you have not used the “On My Mac” section in Apple Mac Mail, then it is possible to reset the Apple Mac Mail internal database.
Apple Mac Mail showing “Loading…” or “Downloading…” for a long time
If Apple Mac Mail is takin a long time to download email messages or loading email messages for a long time, then can happen if you have just added an email account to Apple Mac Mail and it needs more time to download email message, or if the internet connection has become slow or a slow wifi network connection.
Apple Mac Mail stuck on “Updating” or “Connecting to server”
If Apple Mac Mail is stuck on the message of connecting to the service, then make sure that the Apple Mac computer is actually connected to the internet and the computer can browse online to websites, then restart the Apple Mac computer, quit Apple Mac Mail from running, and then again check the internet connection.
Apple Mac Mail not showing recent messages
If Apple Mac Mail is not showing recent messages, then the Apple Mac Mail account might not have fully synced with the email service provider. Apple Mac Mail will only show recent messages if the email account is online, the password is correct, and the email settings are correct. If the Apple Mac computer has been updated or upgraded, or if the Apple Mac computer has been set to optimise storage with Apple iCloud, then Apple Mac Mail might not show recent messages until the Apple Mac computer has completed indexing the internal storage. Also, if you have more than one email account set up in Apple Mac Mail, or you have a large number of emails, then Apple Mac Mail might take time to show recent messages. By making sure that the email account is online, and by checking the email account settings, and by making sure that the Apple Mac computer has enough free storage space, can help with Apple Mac Mail not showing recent messages.
Apple Mac Mail showing blank message windows
if Apple Mac Mail is showing blank message windows, then the Apple Mac Mail message database might not have fully loaded or the email account might not have completed syncing. Apple Mac Mail can show blank message windows if the Apple Mac computer has been updated or upgraded, or if the Apple Mac computer is indexing the internal storage. If you have a large number of emails, or you have more than one email account set up in Apple Mac Mail, then Apple Mac Mail might take time to show the message content. Also, if the email account is offline or needs to be re-authenticated, then Apple Mac Mail can show blank message windows until the email account has been signed in correctly. Making sure that the email account is online, and checking the email account settings, and making sure that the Apple Mac computer has enough free storage space can help with Apple Mac Mail showing blank message windows.
Apple Mac Mail not authenticating email accounts
If Apple Mac Mail is not authenticating email accounts, then the email account needs to be signed in again using the correct password or by using the modern authentication popup that appears in Apple Mac Safari, Google Chrome, or Microsoft Edge for Mac. Apple Mac Mail will not authenticate an email account if the password has been changed online, or if the email service provider has updated the security settings for the email account. If you use Google Gmail, Microsoft 365, Outlook.com, or Microsoft Exchange, then Apple Mac Mail now uses a secure sign‑in process that must be completed online before Apple Mac Mail can authenticate the email account. If the Apple Mac computer has been updated or upgraded, or if the Apple Mac computer has been set to optimise storage with Apple iCloud, then Apple Mac Mail might need to re‑authenticate the email account before new messages can be sent or received. Making sure that the email account is online, and checking the email password, and signing into the email account online can help with Apple Mac Mail not authenticating email accounts.
Apple Mac Mail not verifying account settings
If Apple Mac Mail is not verifying account settings, then the email account needs to be checked online to make sure that the password is correct and that the email service provider has not updated the security settings. Apple Mac Mail will not verify account settings if the email account needs to be re-authenticated, or if the Apple Mac computer has been updated or upgraded and the email account needs to be signed in again. If you use Google Gmail, Microsoft 365, Outlook.com, or Microsoft Exchange, then Apple Mac Mail now uses a secure sign-in process that must be completed online before Apple Mac Mail can verify the account settings. Making sure that the email account is online, checking the email password, and signing into the email account online can help with Apple Mac Mail not verifying account settings.
Apple Mac Mail not working after a macOS update
f Apple Mac Mail is not working after a macOS update, then the Apple Mac Mail internal database might need time to rebuild or re-index. Apple Mac Mail can stop working after a macOS update or macOS upgrade if the Apple Mac computer ran out of storage during the update, or if the Apple Mac computer has an unstable storage system. When macOS is updated, the Apple Mac Mail database is upgraded, and if the upgrade was not completed correctly, then Apple Mac Mail might not load messages, might not show recent messages, or might not send or receive emails. If all of your emails are stored online and you have not used the “On My Mac” section in Apple Mac Mail, then it is possible to reset the Apple Mac Mail internal database. Making sure that the Apple Mac computer has enough free storage space, and checking that the email account is online, can help with Apple Mac Mail not working after a macOS update.
Apple Mac Mail slow or unresponsive
When Apple Mac Mail is slow or unresponsive, then the Apple Mac computer might be indexing the internal storage or completing background tasks after a macOS update or macOS upgrade. Apple Mac Mail can become slow if you have more than one email account set up, or if you have a large number of emails, or if the Apple Mac computer does not have enough free storage space.
Apple Mac Mail can also become slow if the email account needs to be re-authenticated, or if the email service provider has updated the security settings for the email account. If Apple Mac Mail is slow or unresponsive, then making sure that the Apple Mac computer has enough free storage space, checking the email account settings, and making sure that the email account is online can help with Apple Mac Mail being slow or unresponsive as well as checking that the internet connection is not slow.
