TBSync loosing Ressources

[PotatoCarl]

Your environment

TbSync version: Current Thunderbird version: Suse Tumblweed

Expected behavior

Syncing with account with all Ressources

Actual behavior

Randomly TBSync looses Ressources (e.g. Calendar, Contacs). They are not displayed anymore. Account has to be deleted and reconfigured.

Steps to reproduce

Use TBSync for some time

[t0mcat1337]

Same for me.... suddenly after arbitary amounts of time ressources like contacts or calendars disappear. What helps is to deactivate and reactivate the affected account. After it had re-contacted the server "contacts" and "calendars" appear again.

Would like to provide a debug.log of tbsync but on every start of thunderbird it gets overwritten, so its hard to freeze the one when the error appears. Couldn't it simply be appended / rotated?

Hi there,

i figured out this happens after each thunderbird update. I am using four calendars (all on MS-exchange), but only the default-calendar is missing after each update. I dont use the contact syncing. This happens since more than one year, i figured out after each update to delete the TBsync account and add it again. This takes less than 1 minute, but doing this all 4 weeks is a bit frustrating.

System

• Manjaro
• Connected to MS active directory exchange-server

Status after updating thunderbird and before fixing TBsync

Status after fixing TBsync

[gituser789]

Update: To bring back the calendar it is enough to deactivate the synchronization account and then reactivate it.

A complete setup (delete and add again) is not necessary.

I'm also seeing this problem on several installs when updating Thunderbird, EAS ressources just get deactivated in TbSync.

Is there a workaround to prevent having to reactivate ressources after each update ?

I can confirm this faulty behavior as described above. However, I cannot observe:

1. that this is bound to TB-updates being performed. Actually, this happens almost every day overnight, even without any update activity. I am using TB sync in Thunderbird on multiple Windows (10 and 11) and an Ubuntu (20.04) devices and this occurs on all of them.
2. I cannot observe any true randomness in calendars that go missing. Rather, all the calendars from one particular EAS account will disappear – solution as described above.

There is no conclusive information to be found in the debug logs. Here are the log messages after booting for the first time after TBsync was last able to sync properly.

Hi, I am seeing the same issue.

The address book disappears and isn't even in the tbsync "available resources" list anymore. I have to disable and enable the EAS account in tbsync, then it comes back.

Saw this issue with an EAS connection to a Kopano server and to a SoGo server with different users on different Win10 Clients. One time with an installed TB and once with a TB portable I use for testing.

Also it just happened without any TB updates being applied. Just left TB open in my testlab client VM, came back the next day and the address book was gone.

cheers Michael

I can see the very same behaviour here as well. It sometimes looks like it might be connected to the same mail account (calendar und address book) being synced to Thunderbird sessions on three PCs. I don't see any connection to TB updates. The old TBSync addon before TB version 102 worked without issues.

The resource - it's always the calendar here - disappears and only shows up as soon as I untick the account from being synced and tick the sync box again: suddenly the calendar is back again, but it has to be re-configured in TB (custom colour and naming has been forgotten). Basically like @gituser789 described as well.

Using TBSync here with the Provider for Exchange ActiveSync, an Exchange mail account and TB 102.8.0 on three Windows 10 machines.

This is very strange, and I have no idea why. If a single resource is removed (but not others), then the server seems to not include that resource for whatever reason during an update request. I did fix an issue in the latest update from a few days ago, where TbSync forgot the entire EAS provider being installed. But I do not think these issues are related.

[t0mcat1337]

@jobisoft How can we give you more infos about this issue for tracking down what's going wrong here?

As I already mentioned above, perhaps it could make sense to let the Plugin write some sort of debug.log, which is always appended and never gets deleted / overwritten. The problem with this log currently is that it is overwritten on each start of thunderbird which makes it very hard to log the problem, as - at a plus - it occurs arbitary / suddenly. I could imagine such a log could clearify the behaviour and show the trigger which leads to this dissapearing of resources.

Indeed!

Sometimes, Thunderbird does start with the resource available as e.g. the calendar is still visible (discernable by the color I've assigned to it) in the daily preview. Only when the plugin seems to start up, the resource suddenly disappears. It also looks to me like the issue might occur mainly when I switch between Thunderbird instances on different Windows machines. When I re-add the resource to one Thunderbird install, it seems to disappear on the other one once I fire that one up...

[gituser789]

default calender lost today. deactivating and activating the TBSync synchronisation resolves the issue.

[wiraki]

The same just happened to me. Glad to find I am not alone. Workaround (de-activate re-activate account) also works. Let us know how could we provide more info.

[jlanza]

I'm having the same problem. I manage to synchronize it again by selecting the calendars. The issue here is if there is another way not to have to select the available resources and, besides, not to have to change the calendar color :( I have to really thank the developers... if you find a solution for that, great! ... if not I will continue doing the manual stuff ;)

[OneTwoBarbecue]

Any news on this one? Problem unfortunately still persists in in T 115.12.0 with TSync 4.8 and Exchange Provider 4.8. Calendar still vanishes and workaround is still necessary.

Kind regards, Marco
