A customer reported that when accessing Teams chats after migration, users received the following error message:
“Please switch to a different chat where you'll have all your conversation in one place.”
The issue raised concerns that it might be linked to the chat migration process.
This problem is not caused by Quest On Demand Migration. Instead, it is a Teams client-side issue or may relate to Microsoft cross-tenant communication settings.
The error has been documented in Microsoft forums.
It can occur regardless of whether a Quest migration has taken place.
Since the issue is unrelated to Quest migration, customers should troubleshoot using Microsoft Teams guidance:
Check Teams in the web version – Often the chats are accessible via Teams on the web.
Update or reset the Teams desktop client – Ensure the latest version is installed. Try clearing the Teams cache if issues persist.
Review cross-tenant settings – Verify if external access or cross-tenant communication policies are causing the behavior.
Consult Microsoft resources – See the Microsoft Q&A thread for reference:
How do I resolve this error: "Please switch to a different chat where you'll have all your conversation in one place".
If the issue persists after following Microsoft’s steps, it should be escalated to Microsoft Support, as it is outside the scope of Quest migration tools.
