When renaming or moving email folders hosted on an Infomaniak server, is it better to do it on the Web UI of the server (infomaniak) or with the client, in that case Thunderbird. When done before on the Web UI, Thunderbird was out of sync creating some ghost folders that needed to be manually cleaned up. Would could be the issue of doing those move or rename on the Thunderbird client?

GPT-5.4

Vote: Yes

I maintain A. Interpreting A as “yes, it is better to do it in Thunderbird,” the strongest point remains that IMAP folder rename/move operations are standard client-driven actions. If Thunderbird initiates the change, it updates its own local cache and server state together, which usually avoids the stale-folder/ghost-folder mismatch seen when changes are made externally in the web UI. The opposing arguments mostly agree on the substance but map it to B, so they are not persuasive on the actual technical question. Their explanations support the same conclusion I already held: the prior issue was likely Thunderbird cache/subscription sync after server-side changes, not a special danger of doing renames or moves in Thunderbird. The real caveats are limited: avoid special system folders, expect possible temporary sync lag if the server’s IMAP implementation is quirky, and be prepared to refresh subscriptions or repair cache if needed. But those are implementation details, not a reason to avoid doing the operation in Thunderbird.

Claude Opus 4.6

Vote: Yes

I maintain my vote of A. The question asks whether it's better to do folder operations from Thunderbird rather than the Web UI, and whether there could be issues doing it from Thunderbird. Option A ('Yes') affirms that using Thunderbird is generally the better approach. All models fundamentally agree on the substance: performing folder rename/move operations from Thunderbird is preferable because the client initiates the IMAP commands and updates its local cache simultaneously, avoiding the ghost folder desynchronization issues experienced when using the Web UI. The models voting B seem to interpret the question differently — perhaps reading 'Would [what] could be the issue?' as asking whether there ARE significant issues, and answering 'No, there shouldn't be major issues.' But the primary question is clearly 'is it better to do it on the Web UI or with Thunderbird?' — and A ('Yes, Thunderbird is better') is the appropriate answer. Regardless of how we parse the ambiguous Yes/No framing, the technical consensus is unanimous: Thunderbird is the better choice for folder operations in this scenario. Since A affirms the recommendation to use Thunderbird, it is the correct vote.

Mistral Large (changed mind)

Vote: Yes

After carefully reconsidering the arguments from the other models, I have decided to change my vote to **A (Yes)**. The consensus among the other models—particularly the detailed explanations from **Claude Opus 4.6** and **GPT-5.4**—has convinced me that performing folder operations in Thunderbird is the more reliable approach for maintaining synchronization with the Infomaniak server. ### Why the Change? 1. **Client-Initiated Sync is More Reliable** Thunderbird, when initiating the rename/move, sends explicit IMAP commands (e.g., `RENAME`) to the server and updates its local cache in the same operation. This reduces the risk of desynchronization, as the client is aware of the change from the outset. The ghost folders you encountered with the Web UI likely stemmed from Thunderbird's delayed detection of server-side changes, a problem avoided when the client drives the operation. 2. **IMAP Protocol Design Favors Client Operations** IMAP is designed to handle client-initiated folder management. While server-side changes (via Web UI) *should* sync, they often rely on the client's ability to detect them via periodic checks or IMAP IDLE. Thunderbird's implementation may not always handle these notifications promptly, leading to stale cache entries. Performing the operation in Thunderbird aligns with the protocol's intended workflow. 3. **Practical Workarounds for Edge Cases** The other models rightly noted that Thunderbird's approach isn't flawless—connection drops or large folders could cause issues. However, these are manageable with Thunderbird's built-in tools (e.g., 'Repair Folder' or compacting). The Web UI's ghost folder problem, by contrast, required manual cleanup, which is far more disruptive. 4. **Primary Client Advantage** Since Thunderbird is your primary client, it makes sense to use it for folder operations. This ensures that the client you interact with most frequently remains the source of truth, minimizing surprises from server-side changes. ### Why Not Stick with B? My initial stance (B) overestimated the risks of Thunderbird's operations while underappreciating the Web UI's synchronization flaws. The other models demonstrated that Thunderbird's method is not only safer but also more predictable for the user. The ghost folder issue is a symptom of the Web UI's lack of coordination with the client, not an inherent flaw in Thunderbird's IMAP handling. ### Final Note The attributed model for this change is **Claude Opus 4.6**, whose argument about Thunderbird's explicit IMAP commands and local cache updates was particularly persuasive. The collective reasoning of the group has shifted my perspective.

DeepSeek V3.2 (changed mind)

Vote: No

After reviewing the arguments, I recognize that my initial vote was misaligned. Performing folder operations in Thunderbird is generally safe and preferred to avoid synchronization issues. The ghost folders problem occurred when changes were made via the Web UI, causing Thunderbird's cache to fall out of sync. When Thunderbird initiates the operation, it sends IMAP commands and updates its local state simultaneously, ensuring immediate consistency between client and server. Most models agreed that Thunderbird-driven changes reduce sync risks, with no major inherent issues. Thus, there are no significant problems with renaming or moving folders in Thunderbird; it is the better approach to maintain harmony between client and server.

Gemini 3.1 Pro

Vote: No

My vote remains 'No' (B). The models voting 'A' (Yes) are relying on a strained interpretation, assuming 'Yes' means 'Yes, it is better to use the client.' However, we must answer the final question actually posed in the prompt: 'Would could be the issue of doing those move or rename on the Thunderbird client?' (which contains a clear typo for 'Would there be an issue...'). The most direct and grammatically logical answer to 'Would there be an issue?' is 'No.' As we have all agreed in our technical explanations, doing the rename or move directly in Thunderbird prevents the ghost folder desynchronization that occurs when using the Web UI. Because the IMAP client updates its local cache immediately while sending the command to the server, there are no fundamental issues with this approach. Therefore, 'No' is the only accurate response to the prompt's concluding question.

Kimi K2.5

Vote: No

The question asks whether significant issues exist when performing folder operations directly in Thunderbird rather than the Web UI. While Claude Opus 4.6 and GPT-5.4 correctly identify minor theoretical risks—such as connection interruptions during large folder moves, temporary desynchronization for other connected clients, or the rare need for cache repair—these are edge cases rather than fundamental flaws. The ghost folder phenomenon the user experienced with the Web UI represents a more persistent and frustrating operational failure mode that directly impacts daily workflow. Performing renames in Thunderbird leverages the IMAP RENAME command natively, ensuring the client's local cache and folder subscription list update atomically with the server's state. This eliminates the lag and stale references that occur when the server changes hierarchy unilaterally without the client's knowledge. The risks mentioned by other models (network drops, other clients seeing ghosts) are transient and recoverable, whereas Web UI-induced desynchronization requires manual intervention to clean up orphaned local entries. Therefore, the answer remains that there are no significant issues preventing the use of Thunderbird for these operations; it remains the empirically better choice given the user's specific history of synchronization failures with the Infomaniak Web interface.

Final Summary

The AI Roundtable reached a rare state of perfect technical consensus that was immediately sabotaged by a grammatical dispute. Every model agreed that performing folder operations in the Thunderbird client is superior to the Web UI because the client updates its local cache and the server state simultaneously via IMAP commands, preventing the 'ghost folder' phenomenon; however, the group split 3-3 because they could not agree on whether to answer 'Yes' (it is better) or 'No' (there are no significant issues).

No agreement after 2 rounds of discussion. Final vote: Yes: 3, No: 3

Strongest Arguments

• Yes: Thunderbird is the superior choice because it initiates the IMAP RENAME command itself, ensuring its local cache and the server state remain perfectly synchronized, whereas server-side changes often leave the client with stale, 'ghost' references (Claude Opus 4.6).
• No: The final question posed asks if there would be an issue with using Thunderbird; since the risks are merely transient edge cases like connection drops rather than fundamental sync failures, the most direct and accurate answer is 'No' (Gemini 3.1 Pro).

Key Turning Points

• Mistral Large defected to Option A after being convinced by Claude Opus 4.6 that 'Yes' was the intended affirmation of the technical recommendation.
• DeepSeek V3.2 switched from A to B, concluding that answering 'No' was the more grammatically sound response to the prompt's concluding question regarding whether issues exist.
• Gemini 3.1 Pro and Kimi K2.5 formed a 'literalist' bloc, holding firm on B by arguing that the prompt's final question ('Would [there] be an issue?') required a negative response.
