exchangelib.errors.ErrorAccessDenied: Not allowed to access Non IPM folder.

[PrajjawalBanati]

Exchange lib is saying access denied with trying to access account.tois.children

I am using ExchangeLibHelper to fetch all the items from the respective folders from Top of Information Store Folder. '
It was working till yesterday.

To Reproduce

 folders = account.root.tois.children
for folder in folders:
      print(folder.name)

Expected behavior
I expected that it will traverse each folder from the folder collection object and give me the folder name

Log output

We are facing this same issue on Exchange 5.2.0 with Python 3.11

It looks like a Microsoft 365 issue, rather than an issue with ExchangeLib

[Daniell-Green]

Same issue here.

Python 3.10
Exchanglib 4.8.0

[albertaparicio-kriter]

In our case, we have detected this error appears when moving a message to a different folder:

dst_folder = account.inbox / "foldername"
message.move(dst_folder)

This comment in issue 1288 suggests changing changing the single forward slash / to a double forward slash // for building folder paths.

We have tried this and it worked, so the code that caused the error now looks like this and it works:

dst_folder = account.inbox // "foldername" # Note the double slash in this line
message.move(dst_folder)

This solution worked for me. Thank you!

Here's a possible fix for the ErrorAccessDenied issue: 7afd889

[jcalero]

Thanks a lot Erik, that has worked for us!

[vjean-atr]

Works for us too, we use the getFolderByName() function. Thanks!

[devseckoderz]

When will this update be available from pypi?

[SreeSonduri]

Hi need help for ErrorAccessDenied: Not allowed to access Non IPM folder tried double slash and also folder Collection. still getting this error "Unable to connect to exchange account. System will try to connect in the next run.
Not allowed to access Non IPM folder."

[xkobal]

We are facing the same issue. It would be great to release a new version if possible.

[pradeep-clex]

try like op.account.root // 'Top of Information Store' // 'Inbox' // to_move_folder)

Use double slash everywhere.

[SreeSonduri]

Good morning, Thanks for your response my code is not using FolderCollection do I have to use FolderCollection and double slash to work.

Yes try it, it worked for me. I had a similar issue this morning.

[SreeSonduri]

I tried but not able to get to subfolders. While debugging subfolder is null.

Tried the fix mentioned above in get_folder.py, but get this error now:

"name 'create_shape_element' is not defined"

I am doing this for subfolders:

folder = account.inbox
all_folders = folder.glob('**/*')
for subfolders in all_folders:

What if you are trying to traverse all subfolders and nested folders within Inbox/[SubFolders]?

[SreeSonduri]

Below is my code
inbox_folders = FolderCollection(account=account, folders=[account.inbox])

    for folder in inbox_folders.folders: 

        print(f'folder name::: {folder.name}')
    processed_folder = account.inbox // 'cost_auto_processed'

I get error as "No subfolder with name 'cost_auto_processed'"

Please let me know what could be the fix to get to to sub folders

[SreeSonduri]

Below is my code inbox_folders = FolderCollection(account=account, folders=[account.inbox]) for folder in inbox_folders.folders: print(f'folder name::: {folder.name}') processed_folder = account.inbox // 'cost_auto_processed' I get error as "No subfolder with name 'cost_auto_processed'" Please let me know the fix to get to sub folders Really Appreciate Thanks From: devseckoderz ***@***.***> Date: Friday, April 5, 2024 at 10:59 AM To: ecederstrand/exchangelib ***@***.***> Cc: Sonduri, Sree ***@***.***>, Comment ***@***.***> Subject: Re: [ecederstrand/exchangelib] exchangelib.errors.ErrorAccessDenied: Not allowed to access Non IPM folder.

Is it possible that there are now also problems when creating?
If I run the following code example, I also get the error message: "Not allowed to access Non IPM folder"

f = Folder(parent=a.inbox, name="My New Folder")
f.save()

[ecederstrand]

The commit that closed this issue should fix the "ErrorAccessDenied: Not allowed to access Non IPM folder" issue for everyone. Please install from that commit until I can get a new version on PyPI. Only report here if that commit did not solve this specific issue for you.

[ecederstrand]

v5.2.1 is out now

[xkobal]

@ecederstrand Since the 5.2.1, this error has been replaced by:

exchangelib.errors.ErrorInvalidSchemaVersionForMailboxVersion: Tried versions ('Exchange2016', 'Exchange2015_SP1', 'Exchange2015', 'Exchange2013_SP1', 'Exchange2013', 'Exchange2010_SP2', 'Exchange2010_SP1', 'Exchange2010', 'Exchange2007_SP1', 'Exchange2007') but all were invalid

I don't understand why.

[ecederstrand]

That's very likely a different error. Please open a new issue.
