Cloud Drive Mapper v2.25

DOWNLOAD

Background:
Microsoft informed us of the upcoming removal of RPS from SharePoint on October 15th 2025. This will stop CDM 2.22 or below from being able to authenticate to Microsoft 365 and thus be able to map drives for users. We created a work-around to this problem in 2.24, and so we recommend all CDM V2 customers upgrade to 2.24 (or higher) as soon as possible to avoid disruption by Microsoft’s changes to RPS.

2.25 however is an optional incremental update to 2.24 that provides optimisations to Converged drives.

If you already have upgraded to 2.24, you do not need to upgrade to 2.25 unless you are experiencing performance issues with your Converged drive and are directed to upgrade to 2.25 by our support team.

If you have not yet upgraded to 2.24, and are still using 2.22 or below, you can upgrade straight to 2.25 and it will also protect you from the upcoming RPS changes.

Full Release Notes

Improvements

  1. Performance and efficiency improvements to the enumeration of the Converged drives and honoring of retries, which brings greater protection from API throttling.
  2. Reduced the number of calls by approximately 1/3 required to mount Converged Teams drives due to a more efficient use of ArchivedTeams
  3. Introduction of BrakeMode, which allows CDM to be set to a low-intensity mode where it reduces the number and frequency of requests to Graph API to reduce the likelihood of throttling with Converged Teams annd Converged SharePoint drives

BrakeMode

    • Reg key in HKLM or HKCU (HKCU Priority) “BrakeMode” set to = “true” or “false” (false is default if reg key is blank or doesn’t exist)
    • This setting will be checked during runtime, so it will take affect whilst CDM is running
    • This will change the settings below from their original values to new adjusted values with a description of what it does


rebuildTimeInMin

the frequency of the change detection (add/remove of teams and SPO Sites)
default: 220-235min
brakeMode: 650-765

cacheRebuildTimeInHours

how long on startup of CDM do we treat the cache data as valid
default: 25 hours
brakeMode: 72 hours

HttpMaxRetries

How many retries we will allow on throttle error from MS
default: 10
brakeMode: 5

ConcurrentHttpRequests

How many requests we allow to run concurrently
default: 5
brakeMode: 1

ConcurrentHttpRequestDelayInMs

How much of a delay between requests when they are queued
