outlook.exe 2019 and 2016 are slow to show incoming emails

Hey
since our rebuild, we have been experiencing users with their outlook programs slow to show new inbox emails, sometimes 20 minutes.
But if you click to show another folder, example drafts and then click back to inbox it may update quicker

Nothing at the moment for mail.log - i did have yesturday a issue with 1 user and had to increase

Code:

vim  /etc/dovecot/conf.d/99-ispconfig-custom-config.conf
service imap{
vsz_limit = 1G
}
default_vsz_limit = 1 G

as 1 user has a humongous mailbox.
related or not? - hmm just checked and his mail size ;;;;;;; LOL = 74 GB!!!!

 

You should check the settings for send/receive groups in the outlook client. I think the default is every 30minutes.

 

just seen this

Code:

2024-11-27T15:01:13.521814+00:00 mx1 mariadbd[774]: 2024-11-27 15:01:13 11630 [Warning] Aborted connection 11630 to db: 'dbispconfig' user: 'ispconfig' host: 'localhost' (Got an error reading communication packets)

and there are a few of them

 

also set that to 1 minute, but only relates to pop no imap

 

Nothing to worry about, if it is not spamming the log. I have a few of these on my mailservers with a lot of traffic every day.

Does this affect other clients aswell or is this a outlook only problem? Can you test this with thunderbird for example?

 

I have found a mail user that in ipconfig states the mailbox is 78GB, i have connected to the client and the outlook.ost file is physically 12.2GB
What gives with this?
The thunderbird responds in a timely fashion. lot of outlooks dont and have a number on complaints about this issue so far.

####UPDATE####
To answer my own question - check that the user has selected to receive all email s from all time and not just the past 12 months.
Its now syncing so i can archive out mails.

 

I have tested and it does look like an outlook only problem.
Thunderbird and evolution work fast, iphone and android phones work fast, thunderbird on phone works fas..
outlook only issue, i have raised an issue about this with pfsense and will confirm if recified or isolated back to my setup, ie. not a firewall issue
