Mac OS Mail is only syncing 30 days worth of my Gmail. How can I fix this?

Hello.

I wasn't having this problem but was curious about it. Here's something you might try:

In Gmail settings on the web, check the setting "Folder size limits" on the "Forwarding and POP/IMAP" page. Mine was set to "Do not limit the number of messages" -- but when I changed it to "Limit IMAP folders to no more than 1000 messages" Apple Mail deleted older messages. When I changed it back, Mail refreshed all the folders and included messages that were a couple of months old in Gmail.

Hope that works!

(P.S. This may be what you already tried, so sorry if this is redundant -- but I remember when I first set up Apple Mail, setting a message limit on the Gmail side didn't work consistently, which is why I changed it to "Do not limit.")

That's a lot! You may already know this (and it would take some experimentation to make sure it works right), but you could....

• Create a new Label on the Gmail Settings / Labels page.
• Deselect "Show in IMAP" on the same settings page for that new label.
• Search for older emails using "Search Mail" and provide a date range.
• Move older emails to the new label by selecting the emails and clicking the "Move to" icon.

When you move the emails like this, they will no longer have the "Inbox" label in Gmail, and because "Show in IMAP" is deselected for the label, emails with that label -- which would normally show as a folder in Apple Mail -- won't be synched. Both things have to be true: the emails can't have the Gmail "Inbox" label anymore (because emails with the label "Inbox" will always get synched), and the new label assigned to them has to have "Show in IMAP" turned off.

Not sure how practical it would be to do this for tens of thousands of emails, but it could be a workaround -- and all the relabeled emails would still be available in Gmail, under the label you assigned to them.

Hey, glad it worked. I agree that something strange happens when you've got a message limit set. When I was testing this, I had a folder that had 1196 messages in it on both Gmail and Apple Mail, but when I set the message limit to 1,000, Apple Mail deleted 400 of them. Counting is hard, I guess!

Cheers,

I bought a Macbook Air M2 nearly a year ago. All was well with outlook.com but recently I can only view one month of emails. I can only see older ones on my iphone. I've been through Google many times and all the tabs it asks you to press (including an Exchange account) are nowhere to be seen on my outlook. So I am utterly confused. I've spent so much time on it and very frustrated.

your server is probably controlling this. My Yahoo mail works the same. If you want to save more you should move those emails to “on my Mac”. Folder

Click on your email folder and from top menu select mailbox, rebuild and see if they get populated.
