  • Outlook sync problems (a lot of them)

Unfortunatly the syn problem in Outlook persists in Version 2025.01.1, and if you enable the cache mode in Outlook you will not see appointments of shared calendars, if you disable the cache mode it works.

I do not think that this is an Outlook problem, we also manage Exchange Servers for customers and there are no sync issues when using the cache mode.

This seems to be a problem which is still not completely solved.

    nettania Contact grommunio support and open a ticket for this case.

      nettania Question, do you have an idea, why I see the same issue with M365 only in caching mode?

          WalterH Have you tried to delete the profile and than to recreate it? In my expierience this helps in most situations (esspecially when the search index is corrupted).

              nettania We only deleted the .OST file, but this did not solved the issue.

                With the new Appliance release and the upgrade of gromox 2.40 we have also sync problems on outlook in cache mode if a new mail is created and sent by Grommunio Web App then the sent folder yould not be synced anymore - also if we delete the mail from sent folder - sent folder gets synced again but then the trash folder stops sysncing as long as the deleted "sent" mail is in the trash

                so it seems there is a problem with mails created in Grommunio Web

                  Fine,
                  there is someone else who posts the same problem as I.
                  I hope anyone from the grommunio team reads this and resolves this problem.
                  I am sure when this problem is solved, the other sync problems are solved too.

                  gromox-2.40.8.9ee79e2-lp156.5.1.x86_64 was released last night, try this update.

                    nothing changed same problem persists

                      We have identified some potential problem here.

                      To support our investigation, we would kindly request you to answer the following questions:

                      • Have you migrated you data into grommunio (we suspect yes)?
                      • If so, from where did you migrate from and how/what tool have you used for the migration?
                      • From when (date, or if you can even recall from which gromox-version) was the store created (the better the estimate, the better to check for us)?

                      Thanks.

                        No there was no migration - installed plain new appliance - empty mailbox - create mail in outlook (cached mode) - gets synced (is available in Grommunio-Webmail)
                        create mail in Grommunio-Webmail - sync errors in outlook cached mode and no new mail created from Grommunio-Web gets synced -
                        switch outlook to online mode - all mails available

                            Its exactly the same for me.
                            New installed yesterday
                            And as described earlier.
                            When Outlook is running, every thing I do in the WEB interface results in Sync errors.

                              @mwilliams:

                              Two setups (with each some outlook cached mode sync problems):

                              Setup one:

                              • With migration from kopano using grommunio's kopano migration script
                              • Mailbox created with gromox 2.16

                              Setup two:

                              • New mailboxes, no migration
                              • Mailboxe created with gromox 2.16 too

                              Both setups encounter the same sync problems.
                              Can elaborate if needed.

                              Now I see this issue in Calendar and Sent Items (Gesendete Elemente).
                              I deled the .OST file and Sent Items contains only 3 mails, the 4. mail was created with G-Web and this mail and all older mails are not synced into my caching mailbox.

                              same behavior with Gromox 2.41.0 update today

                              Christian

                                I am seeing the same issue also at this point I can not even use the web mail interface.

                                I have multiple computers with outlook same account all set to offline cache and if I only use them the sync works fine.
                                I can view the emails on the web and see all emails in the folders I changed via outlook.

                                Were things break is the moment I make any changes even deleting an email the sync messages start flowing.
                                Where I first noticed it is in sent items I had did on the web were not in my outlook.

                                Another thing that happens is once the sync error occurs even is you delete the account or clear the cache for the offline folder outlook will not sync any of the mail into the folder only new items even if they are all on the server.

                                It seems like all the folders except the inbox seen to sync.

                                  I've noticed another pattern, perhaps not correlated to the webapp/offline sync issue.

                                  Most of the outlook offline cache sync problems I encounter are on accounts that open more than one mailbox (user mailbox + another user mailbox), or that are opened by multiple outlook clients.
                                  Most of the sync problems happen when a user moves emails between folders.

                                  Hope this helps the team to find the trigger the issue more easily.

                                  gromox 2.41.7 contains the fix. But the fix du not work as expected.

                                    WalterH Walter in what way does the gromox 2.41.7 fix for this sync issue not work as expected. Don't want to apply it and open more problems

                                    EDIT: It appears that this 'fix' was published before I updated my Appliance instances yesterday and I already have it installed and it certainly has not fixed the sync issues I am experiencing.
