Hello, I have emclient set up with our company emails, and we now have over 145,000 emails.
Syncing a new installation of emclient takes an extremely long time. Even when new events and emails come in or go out, it takes forever.
I’ve had the sync running for 2 hours and only 139 emails have been synced. Unfortunately, I can’t work like this. We need help.

That’s not normal to be slow like that with eM Client, and could be related to “mail server settings possibly incorrect”, or “could be an actual Google Gmail mail server problem” or “could be a resident program running in the background” on computer startup slowing it.
So first check with Google technical support either via phone or website if they are experiencing any connection / speed issues atm as it could be an actual Google problem as @kurt found below and which fixed itself today.
Next if Google don’t have any current connection / speed issues atm, then go to “Menu / Accounts” and click your Gmail account “IMAP tab” and update what your “Server address, Server Port and Security Policy” is, so we can then check for any possible errors in the server settings.
Also under IMAP “Sync Options” further down screenshot what you have set there so we can check if there is any obvious settings wrong.
Lastly if you have any eg: “optionally installed firewall security program” or “optionally installed antivirus program” or “vpn” other than what comes default with your OS, then try completely disable those to test incase of interference.
I had the same problem for the past few days… the synchronization of emails from the Gmail IMAP server took forever – even though there were only 20 emails to sync.
The synchronization of contacts and calendar worked as usual, in fractions of a second – as did the synchronization of POP3 accounts and non-Gmail IMAP servers.
I experienced the slow Gmail IMAP synchronization problem on two different (Windows 11) PCs.
However, the problem disappeared today, without me having made any changes.
So it seems likely that there was a problem with Gmail… ???
Or was it one of those rare cases of self-healing?

not to hijack this thread, but i’ve been wrestling with this exact issue for the last 4 days.
Migrating to emClient from other apps. Mac runs sweet as a nut, iOS Ipad M2 Pro and iPhone 15 Pro Max laaaaaaaaggy… have the latest app versions and iOS 26.2 on both.
Regular IMAP accounts sync hundreds of messages a minute, Gmail maybe 5. I have an account with 10k messages, left the app open and iPad running overnight, sync’d about 2.5k messages over 8 hours. Removed that account, re-added it - same slow sync.
No AV or VPN on these, i even turned off private relay to no avail.
Whats a little weird is new messages come through right away, its sync’ing all the old emails thats the issue.
Can you please enable IMAP logs for the affected Gmail account (Settings - Account - IMAP - Scroll down to ‘Enable diagnostic logs’) and send them to us for analysis?
After you enable the logs, please restart the app and after you notice slowness/new messages loading poorly, send the created logs (Settings - Help & Feedback - Send logs) and the details on your app version/device to [email protected] so our team can look into it.
Thank you for your cooperation!
done thanks. I’ll wait to hear from them.
