Outlook sync problems (a lot of them)

If you see errors like: "E-1992: The buffer pool "http_blocks_allocator" is full.", set: /etc/gromox/http.cfg:context_num=1800.

ozy If you have this errors, than in journalctl -f.

WalterH If you have this errors, than in journalctl -f.

fyi,

% journalctl --help |grep -- -g
  -g --grep=PATTERN          Show entries with MESSAGE matching PATTERN

Hi,
this corresponds with older problems, that the cache modus for shared folders does not work correctly in Grommunio, see e.g.:
https://community.grommunio.com/d/1459-synchronisationsproblem-freigegebene-kalender/8
Can you have a look if you have also the problem that events of shared calendars are not shwon in Outlook, see:
https://community.grommunio.com/d/1855-entries-of-shared-calendars-not-shown-in-outlook-in-latest-version/3
I have this problem on our server, which is always used as "beta test" before I update clients systems.

ozy Do "standard" shared calendars work if you don't open other mailboxes

you can just share a calendar to a user and open the mailbox via advanced and it will only show the calendar.

i also do that with folders so i won't see the whole mailbox but only things like inbox+etc for stuff like server/monitoring/ticket@ where all the mails fall in.

that way you don't have to see the whole thing but only what you are actually interested in and the rest won't have anything in it anyway.

for how to configure shared mailboxes have a look here

The "open shared calendar" option sometimes works and sometimes not somehow so i always recommend the way via the "Advanced" settings.

Hi All,

I have the same issue... I have (for testing purposes) two grommunio servers. One is installed from the ISO that Grommunio provides. The other one is using the Debian Repo Install.

Both are updated to the lastest and greatest.

However: On the Debian System, the sync is only working if I disable cache mode in outlook.

On the "appliance", it works.

I noticed that on the ISO Image provided by Grommunio the PHP Version used is 8.0 whereas on debian the debian version is 8.2. Could this be one possible cause?

(I tried to switch the debian install to 8.0 but that didn't really work. I will try to check the PHP Settings - the Debian Install Guide does leave quite some things open to your imagination... the documentation could use some help :-) )

tobiasgoeller I noticed that on the ISO Image provided by Grommunio the PHP Version used is 8.0 whereas on debian the debian version is 8.2. Could this be one possible cause?

The old ISO is SuSE 15.5, now most Appliances are updated to SuSE 15.6 which provides PHP 8.2.

Second point, the Outlook connectivity do not use PHP, Outlook is served only by gromox-http.

Is it possible that this is the same problem described in my post
Outlook Sync from Grommunio Server to outlkook hat Probleme ?

Is this a question for me?
yes I unchecked "download shared folders"
Ok the problem is as followed:
I generate an appointment in the grommunio web interface.
then I get 5 error messages

I am currently experiencing sync issues in Calendar and I suspect this is an Outlook issue. My sync problems started about 10 days ago and the last grommunio update was about 15 days before that, so I expect an Outlook problem for the calendar sync problem.

I cannot believe its an Outlook Error.
I tried it with several Outlook.
Starting with an installation from
grommunio-offline.x86_64-2023.11.3-Build5.1.install.iso
in virtual box
with this everything is ok.
Than update in the web interface.
Now I have the sync errors
Really I did this with different Outlook Versions.
But it is not only in the calendar.
When I start a new E-Mail I get the Sync Errors too.
This is when the mail appears in the folder
Entwürfe

I have installed
grommunio-offline.x86_64-2025.01.1-Build2.2.install.iso
in virtual box
the sync problems are the same

I have just been to a customer who uses M365. This problem also occurs with M365! In caching mode the calendar is almost empty (a few entries are displayed) and in online mode all appointments are available. This can therefore not be a grommunio problem.
There will be error messages if the outlook has problems with calendar elements, which Outlook also documents.

We've just migrated around 100 accounts from Kerio to Grommunio and we also see lots of sync issues over the EAS interface. Outlook of course, but e.g. also on Mac if we connect the accounts via Exchange instead of IMAP.
So I'm afraid it's really related to the EAS part of Grommunio.
The latest update from this week doesn't help either.

Also it doesn't only affect the calender, but also mails older than 11-12 months (can't be defined exactly, sometimes two mails from the same day a few months ago behave differently, one loads, the next only shows headers.

Are there any known/supposed workarounds for this?
It's actually quite disappointing how unstable this seems once it's running with more users (as we've had id running with ₁₀ users for a few weeks with no issues).
