Trouble using Outlook and IMAP

Post by LCyphre » 2017-10-21 15:57

Hello Board,

I'm using hMailserver (5.6.3-B2249) and Outlook (14.0.7188.5002).

I have created some Public Folders and use them with some colleagues.

We are facing following problem:

Accessing public folders with a flat folder structure is ok.

Accessing public folders with a deep and wide structure takes up to several minutes.

Moving messages or folders is also a problem.
Outlook hangs.
Reports error messages.
Outlook shows folder structure but messages are populated several minutes later.

Using Thunderbird is ok. Unfortunately we have to use Outlook.

I drilled down the problem to the following:

Thunderbird uses

SELECT "Folder"
Response: 3 EXISTS
FETCH 1:* (UID FLAGS)

to fetch the content of a folder. Everything is fine.

Outlook uses

SELECT "Folder"
Response: 3 EXISTS
* FETCH 3 (UID)
after FETCH completed Outlook starts to LIST unrelated folders.

After listing unrelated folders there is a

* FETCH 2 (UID)
* FETCH 1 (UID)

Hopefully someone can confirm this behavior and has a solution.

Regards

LCyphre

Unfortunately not one you'll like.(don't use Outlook for IMAP it's terrible)

Welcome to the world of IMAP + outlook, where standards are not followed.

Interestingly though...
perhaps that information can help with this issue that has been plaguing us for years >> viewtopic.php?f=10&t=28598
Just 'cause I link to a page and say little else doesn't mean I am not being nice.

Dear mattg,

thanks for your quick reply.

I have seen a second version of the fetch command.

Sometimes Outlook uses

FETCH 1,3 (UID)

hMailserver response:

* FETCH 1 (UID 1)
..
* FETCH 3 (UID 3)
..

Outlook then also starts to LIST unrelated folders.

Regards

There are some indications the newest MS-Office Outlook doesnt have this sort of Problems anymore or atleast there are no reports of any UID Problems with the newest Outlook versions.
