You can use IMAP or POP3 protocol to configure your Gmail account in MS Outlook. However, after using IMAP account in Outlook for some time, many users want to change their mail settings from IMAP to POP. Today we will discuss how quickly you can change your IMAP configuration to POP3.


What is IMAP?


IMAP stands for Internet Messages Access Protocol. In an IMAP configuration, the email client keeps a copy of the mailbox on the local system without deleting it from the email server. The advantage in this case is that you can access your complete mailbox data through various devices (of course with proper IMAP configuration).


Advantages of IMAP


  • Quick and easy access to emails from different geographical locations.


  • In IMAP, any items deleted from the user system is still available on the server.


What is POP3?


POP3 is an abbreviation of Post Office Protocol version 3.  When your email application is configured with POP, then all your emails are downloaded to your email application. Then emails can (and should) be permanently deleted from the mail server.


Advantages of POP3


  • Your emails are stored on your system hard drive. Each time you configure POP3 on a new device, only the additional emails will be downloaded. This saves time in configuring the email account.
  • In POP, opening and accessing attachments are quick because all the attachments are already downloaded.


Step by step procedure to convert IMAP to POP


To start this process, open MS Outlook and start the below-mentioned steps:


  1. Click on File > Info > Account Settings.



  2. Then click on New to add a new account.



  3. Select Manual set up or additional server types and then click to Next.



  4. Now select POP or IMAP and then click to Next.



  5. Enter your POP details and then click on More Settings.



  6. Then move to the Advanced tab and enter POP and SMTP port numbers and click OK.

    Note: Here, you have an option to leave copy of messages on the server for a definite period.

  7. It will take few seconds, and your POP account is successfully added to Outlook.


Steps to remove IMAP account from MS Outlook


After successfully adding your POP account, you can remove your IMAP account from Outlook.


  1. Click on File > Info > Account Settings.


  2. Then select the IMAP account and then click on Remove button, your IMAP account is successfully removed
    .


Migrate IMAP to Cloud


Recently many users are migrating their IMAP email data to cloud emailing platforms like Office 365. This process is easy if you are using a third-party tool for migration.


Kernel for IMAP to Office 365 is a brilliantly developed and designed tool to migrate IMAP account to Office 365, hosted Exchange and on-premises Exchange. With this, you can quickly migrate those mailboxes which are configured with IMAP settings.


You can also migrate single as well as multiple mailboxes from IMAP email servers to Office 365. And this tool allows users to migrate emails to mailboxes, public folders and archive mailboxes in Office 365.

If you are a SharePoint user, you must know how tricky it is to perform SharePoint migration. A lot more practice, planning, evaluation, and then execution is needed to make sure that the data is safe and secure.

So, before you start the migration, let's have a look at the migration checklist that will help you ensure success in the whole process.

  • Analyze new environment configurations and then configure the required settings at destination environment. It is like planning and plotting new home.
  • Cordial communication with users 
  • Now you can start the migration 
  • You need to put the system in read-only mode until the migration process gets completed.
  • After the migration is completed, you need to review and make sure that everything works perfectly. 


So, a lot of things to do but do not worry, as Microsoft has been making the things easier for you.


Well, you no longer need to face challenges of SharePoint migration as Microsoft has introduced the SharePoint Migration Tool that allows you to migrate your files from SharePoint on-premises document libraries and shift them to SharePoint. If you are an Office 365 user, then you can move to OneDrive and Office 365.


Microsoft has developed software for migration purposes, and you are allowed to migrate from a single file to multiple file sets. The tool is using the latest technology; therefore, bringing your information to the cloud. It also takes up intelligence, latest collaboration, and security features with Office 365.


The software is completely free, and the best part is, you aren't bound to be a global admin or a SharePoint admin in Office 365 to operate the software. To migrate data by using this tool, you need the write access to the destination SharePoint Online site collection.


  • Download the tool by visiting SharePoint Migration Tool Version 1 if you want the current release or you may also visit SharePoint Migration Tool V2 Beta release if you want to use the newly released V2 beta version.
  • Check the check box to agree to terms of service and privacy policy and click the Install button.
  • Click Yes to allow the installation.

As a matter of fact, Outlook OST files are of much importance in relation to Exchange mailbox. OST files are independent as they are simply copy of data of a user’s mailbox on Exchange Server. Though, if the server’s status is changed or it is damaged, the OST files will not be affected. Due to these files any user can work uninterruptedly during the server downtime in offline mode. Later, when the server is online all the data gets synchronized automatically with the mailbox server.


After understanding the importance of an OST file, are you at a situation where OST file got corrupt and searching for an accurate and efficient solution? The best solution is OST to PST converter software that aims to provide solid results and proves to be helpful. Before moving towards detailed solutions, let’s discuss the errors and reasons behind them.


The regular users of Outlook might come across OST file corruption or accidental file deletion issues. This indeed is not a common problem, but if it takes place then it can be worse for the entire business. Due to the inaccessibility of OST files while launching MS Outlook, the user is indicated with several pop-up errors, indicating corruption.


The following errors occur when OST files gets damaged, corrupted or inaccessible:


  • Could not find YYYY.ost (business file) in Outlook storage
  • The YYYY.ost is not available in mailbox
  • Errors detected in YYYY.ost, therefore, to fix and repair the file try using Scanost.exe
  • File is not accessible is also an error
  • The OST folder is displayed
  • MS Outlook encounters a problem and exit suddenly


Before suggesting the fixes for the mentioned errors, let’s take a quick look at the primary reasons that may cause these error:


  • Outlook is suddenly terminated while synchronization with Exchange server
  • Sudden system shutdown during Exchange server synchronization
  • Corrupt file system
  • OST is attacked by virus


Repair techniques for OST file


There are many reasons for an OST file to get corrupted and the major errors may occur due to hardware, software and synchronization failures. Here are some repair techniques that can be applied to OST file.


  1. Replace with a backup copy: One of the best suggested techniques is restoring from a backed up copy. Unfortunately, this technique follows some limitations, say for instance, if the backup is not a recent one then all the data saved after the backup will be missing.
  2. Use inbuilt Inbox repair utility: ScanPST.exe and ScanOST.exe are two inbuilt utilities that are offered by Microsoft to help repair minor issues related to Outlook OST and PST files.
    There are some drawbacks with this technique. Firstly, severe corruption issues are not fixed by ScanOST.exe. Secondly, this utility is limited to Outlook version 2007. Hence, not available for above versions.
  3. Clean offline data and recreate: By removing the offline data of OST file, it will help you in eradicating the cause of corruption (up to a level).
    Therefore, clear the OST with the below mentioned steps:
    a. Find the OST file on your system.
    b. Select “Properties” by right clicking on the folder.
    c. Choose “Clear Offline Items”.
    d. Click “OK”. And, Outlook will be launched.
    e. From the Outlook 2010 ribbon click the Send/Receive tab and click “Update Folder”.
    Later, delete the OST file after completing the above steps and a new OST will be created and data will get downloaded to it within the Exchange mailbox. Overall this method is not a guaranteed one, but is very effective with minor data loss only in conditions where the OST gets corrupted before the merging of Exchange mailbox.
  4. Use OST to PST converter: This is the most reliable technique offered if none of the above techniques work. Data recovery tool is the most intelligent solution for all corruption issues related to OST file. The most efficient recommended tool by experts is Kernel for OST to PST converter – It is a third party tool that helps users in extracting  data from a OST file into PST format.


Final words


The files you backed on the fly always helps when you face any type of data crashes. Although, it is not a hundred percent solution to solve issues of crashes or corruption of OST files. In such cases, if the manual and free methods fails to work, try using  OST to PST Converter software which will effectively convert your corrupt and large size OST file into MS Outlook PST file format.

Why not just delete the OST file and let Outlook create it? It is only a cache file and not required for Outlook to operate. It will be rebuilt the next time Outlook is run.

Your step 2 is not relevant. ScanPST does not work on an OST file and ScanOST is no longer available: https://support.microsoft.com/en-us/help/983036/the-scanost-exe-tool-is-not-available-starting-with-outlook-2010

The pre-migration analysis is a highly beneficial feature which allows the administrator to evaluate the possible approximate time of migration. It gathers the information about the numbers of agents involved in the migration and the average network speed.


Agent configuration


Agent configuration accelerates the migration process with the configuration of any high-processing machine (if running idle), and helps the large-sized migration. It is also possible to  select a blackout time which will automatically pause the process at a point, and later it can be resumed from the same point easily. 


Easy migration with smaller jobs


Migrator for Exchange decreases the complexity of a large migration process by creating multiple jobs which migrate thousands of mailboxes in smaller batches. Each job can be assigned a migration start time efficiently. 


Web-based migration reports


The administrator can generate the migration report involving complete information of migrated mailboxes and their sizes. It also shows the remaining items and how much will it  require to complete. 


Real-time migration alerts and notifications


The tool constantly updates the user with real-time notifications and alerts either in the software console or directly in the user's mailbox. It provides a complete synopsis about the migration start time, migration end time, status, and migration success/failure information etc.

  • Removes the need of checking every assigned agent separately.
  • Pause the migration process at any point and later resume from the same point.
  • Requires fewer resources.
  • Rollback features to reverse the faulty migration.


How does Kernel Migrator for Exchange work?


Kernel Migrator for Exchange has a self-explanatory user-interface having categorized segments to easily understand each and every component of the migration from their dedicated tiles.


 The user can easily create new projects to migrate mailboxes and public folders.
 
After creating a new project, the tool allows to create a new job for the migration purpose.



Before starting the actual migration, the tool offers a pre-migration analysis which assess the approximate time required for migration based on total number of agents and network speed.


Pre-migration analysis  

Enter the Job type, job name, domain controller name/IP, username, password, network speed, and number of load agents.


The next window lets you select the number of mailboxes.



Then you can set the filters.


As soon as the tool analyzes the input data, it gives a detailed summary of how much time will it require to migrate a particular mailbox, total folder, total items, total size, and status.


SETTINGS

After pre-migration analysis, it is time to change the settings as per your migration needs. There are four types of settings – configure agents, report console settings, notification settings, and log settings.


Configure agents
 Agents are the extra system resources (RAM & Processors) within the same network which can be recruited to share the heavy load. There are four options to install agents – Manually, from active directory, scan and add, and from CSV.



Report console settings
This option provides login credentials to access report console to see details of migration job completed by the Migrator.


Notification settings
This option lets you configure server setting to receive notification alerts.

Log Settings
Log settings lets the user enable or disable the logging of mailbox migration jobs and mailbox synchronization jobs.


Mailbox configuration
It is the most important pre-migration function which lets the user set the migration limits, properties, and permission of user mailboxes and public folders from the source exchange server to destination exchange server. However, there are multiple prerequisite which must be fulfilled

  • The user must have the full administrative rights to create all migration jobs.
  • If you are going to update profile job, make sure that GPMC (Group Policy Management Console) is installed on system where Kernel Migrator for Exchange is installed.
  • To migrate to different language version of Exchange server, install the target language based Outlook on the same computer where the Migrator tool is installed.


GAL Synchronization


The Global Address List synchronization updates the Global Address List of Target Exchange with respect to the source migration objects.
In the GAL Sync wizard, enter the job name and its description.

 

 In the next window, enter the source domain details.


In the next window, enter the target domain details.



After a proper synchronization, it will give a complete GAL synchronization job details.



Add Project
After completing all the synchronization, it is time to add project to manage all migration jobs. To create a job under a project click Add button in toolbar and select "Add job for mailboxes".



After creating a job and providing a name to it, select the source.



After selecting the source mailboxes, employ the target exchange server.



After filtering the desired data and mapping target mailboxes to source mailboxes, you can start migrating data.

After a successful migration, the tool will provide a detailed summary of the whole procedure.


Click Finish to finalize the process.

However, it is recommended to first generate and activate the licenses to ensure smooth data migration throughout the process.
