Why Thunderbird Inbox is Full, Can’t Hold any More Message Errors?
- If users have not cleaned their Thunderbird accounts up over time.
- Users have a significant quantity of messages, and the PC is no longer acknowledging new ones.
- Because Thunderbird mailbox directories never exceed the 4 GB limit, this may be an actual cause.
- Thunderbird storage files have been deleted or isolated by an antivirus or firewall.
- When there is an issue with the Thunderbird MBOX files.
Solving the Error: Thunderbird Inbox is Full & Can’t Hold More Messages
There are three main hotfixes through which the error can be solved.
Deletion
Sometimes, Installation and uninstalling hardly make any sense. The problem arises with mail files and for it, there is no need for installing/uninstalling Thunderbird. So, the best possible solution to solve this error Thunderbird inbox is full is a deletion of the overloaded emails or moving them to another location.
#1
The contents of the Inbox folder can be exported to any other folder in the list. The emails can be moved in batches in a single attempt. All the user needs to do is press the shift key from the first mail to the last one. Once it is completed, drag it to a new folder. Once you have moved all the messages, the Inbox is empty and there is plenty of space for the incoming emails.
#2
You can also directly delete the Inbox mailbox from the local storage. If you have a POP account, Thunderbird will save all the emails in the local system. Simply take a backup of this file and then delete it. Afterwards, restart Thunderbird and the new empty Inbox will not show the “Inbox is full” error anymore.
Renaming Mailbox
Even the file which holds Inbox as a name can be renamed too. If you are using Explorer, then, in that case, there is no necessity to delete the emails only you need to rename them. It makes the application work in a normal way. It can be treated as a quick fix to get the mail in flow again.
Users can even find out that in Explorer, each file is inclined to a file with a similar name having an extension as MSF. The files are index files that are inclined with folders and can be deleted if the name of the file is deleted or changed. Mozilla Thunderbird creates a new index file. It also keeps separating the index issues if they are deleted.
Compacting
If a single message has been deleted from Mozilla Thunderbird, they are retained as erased or deleted from the email file. To completely delete the files from Mozilla Thunderbird, you need to compact the folders. Compacting folders is a necessary task to do. If you do not compact the folder, it will keep on increasing and can lead to multiple problems. The users should compact folders on the regular basis of all the mailing programs. To ease the efforts, it can be done every week. But, if a user makes it a habit the work will become a quick process. If it is not done at all, the users will come across the Thunderbird Inbox as Full Error again.
Tracing Files
To trace the location where Thunderbird stores its mailbox files, do the following:
- Copy emails to a new folder
- Go to Tools >> Choose Account Settings
- Select Server Settings or Local Folders
- Copy the location details from the local directory from the right side
- Now open this copied location in a New Window.
- Make sure to close Thunderbird and do the steps mentioned above.
- Restart the Mozilla Thunderbird Program after completing all steps.
Contact the Email Service Operator
- Contact the email service providers to increase the mailbox size of the Thunderbird email account.
- Ask the email service Operator to remove a few emails from the server.
A Scenario-Specific Solution Worth Considering
In some situations, the error is not caused because of Thunderbird. But it happens due to your server storage limit. Take this user for example:
His issue was resolved by archiving the old emails from Yahoo itself. So in his case, the error “Inbox is full” became equivalent to something like “Not enough space in Inbox to retrieve emails on server”.
So you can also try to archive/move/delete the emails from the mail server (eg: Gmail, Yahoo, etc.) itself to get rid of the error.
Instant Solution:- If you want to recover deleted data files then try MBOX to PST Converter Software that will assist in restoring data from the MBOX file & extract it into the PST file.
Final Outline
The problem mentioned above happens because of limitations present on the Windows Platform. Maximum times, the file size is huge, even that can get users into problems. The folders or inboxes in Mozilla Thunderbird exceeds by size if it is not compacted or if it comprises of many mails. Henceforth, trying the recommended solution upwards will also be beneficial in solving the Thunderbird Inbox is Full and Can’t hold any more message Error.
