MS Outlook Getting Stuck with Updating the Folder Problem

Problem

I am using MS Outlook 2016 as my mail client. Recently we had our domain changed and we need to move to the new domain. I moved more than 1000 of mails from the old domain folder to the new domain folder. Now the problem started.

• I am unable to get new mails

• When I clicked Update folder or Send All/Receive All button the status is shown as Updating the folder

This issue was there for more than 3 days.

Reason

MS Outlook 2016, which I used was working with “Cached Mode”. All the emails are stored locally and the Exchange server was synching up with the delta. Since the delta to sync up was huge, the outlook was stuck in the synchronization process and unable to update the local cache with new mails. Since the local cache is the master copy of the mails (some mails are not updated in the exchange server) more mails are in the cache and the server was lagging behind in the synchronization process.

Solution

One suggestion was to create a new ost file so that the mails are downloaded from the server. Only the mails from the server will be available in the ost file, but the mails which are available locally will not be present. Around 2 GB of mails were there in the Server. Even it may take another 2 days to download the mails with this solution and the given network speed and bandwidth.

Instead, I kept the ost file as it is and ran the Auto Archive with the latest date. Now all the files are Archived and put under a PST file. Then Compacted the pst files and ost files. Now all my old mails are available in the PST file. I added that pst file in the outlook to view my old mails which are required for my reference. Since the mails are archived to different files, there is no requirement for Synching my local cache with the Exchange server. My outlook is in sync with the Exchange server and nothing to update. Now I got the message “All folders are up to date” in the Outlook Status.
