Outlook 2010 w/GoDaddy IMAP email syncing

Question

We're having a host of issues that may translate to Outlook not being an ideal client for IMAP, but I am hoping the forum can provide insight to determine if it's a provider issue or a MS issue.
Specifically, we're having an issue using Outlook 2010 with the IMAP solution from GoDaddy.
After email is received in the Inbox, if the user manually moves emails to non-IMAP folders (an offline PST), they will appear to move to the folder, but then reappear in the inbox a short time later. This also happens with deleted emails- they'll disappear
from the inbox only to reappear a short time later. If you check webmail, you will see that the moved or deleted email still resides in the inbox. (Note- if you are working in webmail with Outlook open and delete a message from within webmail, it's instantaneously
deleted from the Outlook client, which is great, but we need it to work from within the Outlook client this way too- it deletes or moves immediately on the server).
It seems that what is happening is that either Outlook is not sending the proper command to the server that a message was moved or deleted OR perhaps the server gets the command, but fails to perform the action.
GoDaddy said that the only thing it could be is a "known Outlook issue" wherein message flags are not being delivered to their servers from the Outlook client. I've asked a number of reliable engineers and they've never heard of this issue (but think IMAP
is wonky in general).
I have a harder time accepting that because other IMAP accounts seem to work in Outlook, and if flags/commands were not being sent from Outlook, then in theory, none of these accounts should work. Additionally, it's not consistent- sometimes it does work.
Outlook settings are correct according to the provider. Also, in Outlook, under More Settings->Deleted Items we DO have the Purge
items when switching folders online option checked, as most of the time, we do want the deleted items to go away if we switch folders. I have noticed that sometimes, but not always, if I move/delete a message and then switch into the folder where
it was moved to check that it is there (or another folder entirely to do other work), it doesn't return to the inbox as described above. It's not reliable, and isn't a real solution to the issue, and is not practical to do every time.
It's a huge problem for us because if you spend 40 minutes filing away your email only to have it all pop back to where it was, you've wasted a huge amount of time.
Any thoughts greatly appreciated.

Hi,
Here is what you may try:
1. Firewall and anti-virus software. Turn it off to check the result
2. Any add-ons effected. Start Outlook in safe mode to test. ("Outlook.exe /safe")
3. Test compact the folder after deleting an email. It might be an known issue with Thunderbird client.
4. Any mobile phone sync with account? Remove all mobile device if you have.
Thanks.
Cheers,

I disabled AV completely and Outlook 2010 with IMAP still has problems with disconnects & timeouts.  I recently contacted GoDaddy about this very same thing and got the exact same responses, and Microsoft still denies there's a problem...  
These Outlook/IMAP problems have persisted for YEARS!
The problem seems to be one of performance – synchronizing IMAP folders is terribly slow, resulting in chronic disconnections, timeouts, delays of ~4 minutes to delete a message, and lots of user frustration that takes up a lot of my time and I cannot justify
billing for it all. This morning one of my clients reports Inbox messages that have already been read and filed into other folders have just reappeared in their Inbox. I think this is symptomatic of the overall performance problems.  The situation is
horrible and getting worse. GoDaddy & Microsoft need to resolve this NOW.
The problem appears to be Microsoft's.  I have recently tested Outlook 2010, Windows Live Mail 2012, and Zimbra (open source) on the same Windows 7 computer accessing the same GoDaddy email account using IMAP.  Outlook and WLM always have problems,
disconnects, timeouts.  Zimbra exhibits none of these problems.  
It seems to be related to either Microsoft's IMAP protocol timeouts, or IMAP error response handling, or inability to properly handle multiple IMAP threads (for users with lots of sync'd folders).  
Also, telling users to remove mobile devices, or create fewer folders with fewer sub-folders and fewer files in each negates the primary reasons for using IMAP in the first place, so stop it.  We desperately need REAL solutions!
