 Hi there,

I've configured some Outlook 2013 users with EAS. This works great with
smaller mailboxes, no issues (or none of the users told me ;-)

But with mailboxes > 2.5/3GB users are complaining about these issues:

* the initial sync takes "forever" (seems never to complete)
* connection very often drops after a few mails (Outlook displaying
"disconnected" and sometimes does not reconnect automatically)
* some messages are downloaded each time and are multiple times listed
in Outlook
* some attachments are "scrumbled" and listed in plaintext instead as an
attachment

Most (if not all) of these users have lots of folders and messages
inside these folders (mails from 2004 until now...)

The server is hosting about 30 mailboxes (small business), about 10 of
them are connecting with Outlook, the rest is using Thunderbird. On
mobiles active sync works as expected.

I found some advice in bug 3236 [1] and some mailinglist posts [2] but
none of these settings helped. Also tried resyncing some folders or
completely removed and reconfigured accounts with manage-eas.

Tried increasing max_line_length in dovecot from 2MB to 4MB, the timeout
in the apache virtual host is set to 3600. The worker count is set to 30.

The same accounts connected with IMAP sync very fast, no "scrumbled"
attachments.

My question now is, how do I find the optimal settings for EAS are
(MaximumSyncWindowSize, MaximumSyncResponseSize,
WOWatchDogRequestTimeout, SOGoMaximumPingInterval, etc...) ?

I've tried lots of values and nothing seemed to fix these issues. Is
that a trial-and-error solution or are there any optimal settings I can
calculate somehow ?

The server is running Debian Jessie 8.2 with SOGo 2.3.2 / Dovecot
2.2.13. It's a virtual machine with currently 4GB RAM and two
processors, average load never gets higher than 0.5...

but sogo-common is still listed as 2.2.9 - is that intended ? (using the
inverse repo)

ii sogo:amd64 2.3.2-1
ii sogo-activesync 2.3.2-1
ii sogo-common 2.2.9+git20141017-1


Hopefully someone can give me advice how to solve these issues...

Best Regards
Peter

Hi Thomas,

(replying back to the list)

I could not find any exception but lots of messages complaining about
encoding in the logs. Sometimes Outlook shows "disconnected", but in the
sogo.log i still can see ActiveSync entries from this user a while.

I "played" with SOGoMaximumSyncResponseSize - 512, 1024, 2048, 4096 or
even 6144 but none of them solved that issue. My "feeling" was, that 2MB
had the best results from all of them. But then - how does that interact
with all the other parameters ? That is a bit confusing for me. Just
tried to set SOGoMaximumSyncResponseSize to 2048 (and another time to
4096) and commented everything else regarding ActiveSync I've added to
sogo.conf - did not really help. And yes, I also tried the settings
mentioned under "EAS Tuning" in the documentation.

I' fiddling for hours just trying different combinations but none of
them seems to work for me.

Tried EASDebugEnabled, but that's lot of information and mostly it's
just xml/plain mail I can see then (lots of attachments listed in
base64). Did not really help me to find the problem - did not even know
what to look for ;-)

Sometimes outlook shows disconnected while Sogo.log still is listing
attachments in base64. When that is finished it looks like that (without
debugging it's showing just the last line):

As far as I recognized: yes. Even on the same devices it's ok when
getting the messages with IMAP (Tried in webmail, Thunderbird and
Outlook with IMAP). Tried that with two different accounts having that
issue and it was working with both of them when not using EAS.

[SOGo] Problems with Samsung phone ActiveSync NSInvalidArgumentException

2015-10-11 Thread DaveK 
Hello,

Since last Friday (10/2), my Samsung S5 stopped getting emails, while iPad and
Outlook 2013 are receiving them.  Yesterday, I deleted the account on S5
device, and re-added it.  It synced up all emails until that period, but since
then I have not received any new emails today on ONLY that device, while iPad
and Outlook are still showing new emails (same email account on all 3
devices).

I continue to see this in the /var/log/sogo/sogo.log file (I masked email
address and device id):

sogod [15395]: "POST /SOGo/Microsoft-Server-ActiveSync?Cmd=Sync=xxx
%40xxx.com=SEC2Dx=SAMSUNGSMG900V HTTP/1.1" 200 0/87
0.011 - - 0 EXCEPTION: 
NAME:NSInvalidArgumentException REASON:'_name' must not be an empty string
INFO:(null)

The only information I saw on Google searches was a reference to a bad CNAME.
I checked my CNAME, MX, etc records and they look good to me.

Can anyone point me in a direction to try to fix this issue?  I don't really
suspect SoGo, unless I changed something in a config file, but I don't know
where to begin to look.

Samsung Exchange server settings:
Email address:  x...@xxx.com
Domain\username:  \xx...@xxx.com
Exchange server:  mx.xxx.com
Use Secure connection (SSL):  
Use client certificate: 

iPad settings:
Email:  x...@xxx.com
Server mx..com
domain (optional): 
username:  x...@xxx.com
Use SSL:  
S/MIME:  

Thanks,

Dave

Hi Alain,

good to know I am not the only one ;-)
I've also switched (at least the big mailboxes) to IMAP and
CalDavSynchronizer (which will hopefully soon get CardDAV support).

But still hoping someone can enlighten us here on the list...
