eM Client slow with IMAP inbox ~ 30k emails

I have a user with an IMAP inbox with 33k+ emails. Everything works as expected but all operations take a noticeable amount of time, approximately 5 seconds to delete an email or move it to another folder. An interim dialog box pops up saying “this operation make take a while to complete” on EVERY operation. Is this to do with the client? The server? Or the sheer number of emails in the inbox?

Hi, what version of eM Client are you using? What mail service are you using? Are you using IMAP?

Thank you,
Paul.

Paul,
I’m using the latest eMClient 6.0.20154.0. I’m using Rackspace email. I am using IMAP

Can you make a screenshot of your account settings from Tools > Accounts > Your account > IMAP?

Thank you,
Paul.

There isn’t anything special about my settings that I can see:

Hi again, what mail service are you using? Is this a private domain? If so what mail hosting are you using?

Thank you,
Paul.

Private domain using Rackspace email (not exchange)

Can you please try updating your client to this version (http://www.emclient.com/dist/v6.0.20489/setup.msi), if that helps the issue,
I’m afraid this is simply caused by the number of items in your database, in case the update doesn’t help can you also try downloading this tool (http://www.emclient.com/tools/dbrepairrebuildall.exe), and run the tool, it will rebuild your database and that might help speed things up a little.

Hope it helps,
Paul.

Thanks Paul, I’ll give it a go
